I am trying to run my cypress tests when building a project through Travis CI. I am installing cypress fine, however, I was then getting the following error:
I have looked online and in cypress official documentation and the method that they recommend fixing this issue by adding the following into my package.json:
"test:ci": "start-server-and-test http://localhost:3000 cy:run"
cy:run in this case being cypress run. However, when I run this, it does build the server however it then does not seem to run the tests afterwards. It just freezes on the build.
I then call this script within my travis.yml file as shown:
- npm run test:ci
I also have the following as my before_install and install object:
before_install:
- npm i -g npm#5
- npm i -g firebase-tools
- npm i -g #angular/cli
- npm cache verify
install:
- npm i
- npm ci
To clarify - the desired results is that when running Cypress through Travis, the local server (my baseUrl) is run and then the tests are carried out.
Use "baseUrl":"http://host.docker.internal:3000" in your cypress.json

I have been trying to install some packages and libraries like react-dom and react-icons but I have not been able to get any luck.
Every time I run an npm install command such as:
npm install react-icons --save
or:
npm install react react-dom
All I get is a blank line in terminal and my install doesn't go through.
This is irregardless of whether I add --save or not.
It is also irregardless of whether I use something like an integrated terminal in VS Code or my native terminal application.
npm start works and such so I'm thinking its just my install command that is failing.
It might be the case npm is not istalled? Do you have Node.js installed? NPM is included with Node.js installation. In order to check open your terminal and type npm -v. If it's installed you are going to see something like v8.10.0.
I installed npm-run-all and also configured the environment variable (which may or may not be not required) on my Windows machine but am getting an error:
'npm-run-all' is not recognized as an internal or external command,
operable program or batch file
I am trying to build my current project with npm run build which includes the script where the error is thrown:
npm-run-all -p build-css build-webpack
Do I have to do any additional things to make it run?
Make sure the npm-run-all is in your package.json devDependencies.
If npm-run-all is present in your package.json, run npm i
If not present install it, run: npm i npm-run-all -D
If error is still present, follow these steps:
Remove node_modules folder: run rm -rf node_modules
Install all dependecies: run npm i
Hope this helps!
You may just need to run the following command first (from the directory with the package.json file)
npm install
Please do that like this.
npm i npm-run-all -g
And then this issue will be fixed.
You have a couple of options here, besides installing npm-run-all as a global package as suggested by #Vaibhav in the comments:
1) Create an NPM script
The package.json file has a scripts section which can used to define shortcuts for anything you need to run while you're working on your app. There are some pre-defined scripts, like run or test than can be executed with simply npm start/npm test or you can define anything you like and then run it with npm run my-script-name. You could try:
{
"scripts": {
"start": "npm-run-all -p build-css build-webpack"
}
}
Any NPM module referenced here "just works" (i.e. the path to the executable is resolved under the hood by NPM)
2) NPX
In newer versions of NPM (i.e. >= 5.2 or so), the "NPX" executable is provided. This has a similar effect to running commands inside an NPM script. You would run:
npx npm-run-all -p build-css build-webpack
Again, the path would be automatically resolved.
If you have an older NPM install, you can also install it separately:
npm install -g npx
npm install -g npm-run-all
Works for me.
Double check if npm-run-all is in your package.json devDependencies.
I had same problem while using code editor Brackets.
To resolve the error, I did the following steps.
Add nodejs new system variable to your PC under Control Panel -> System -> Advanced System Settings
;C:\Program Files\nodejs\
After that, re-run command:
npm
I don't know if this would help anyone, but I got this error because I was doing nodemon server.js instead of nodemon server/server.js. I wasn't in the right folder!
Did you reopen the terminal after you installed node?
If you have installed npm with the current terminal window open. Your terminal window will not have loaded the latest path settings (with npm location) to find the npm application to run the command. In this case try below steps .
Try closing the current terminal session.
Reopen a new session.
Try the command again ( will pick up the new path settings with npm installed)
This worked for me.
npm audit fix --force
Also you can try downgrading your autoprefixer, seems version 10.0.0 doesn't work well with postcss
npm i autoprefixer#9.8.6
I am trying to create a new react-app and start it, I have created react apps before with no errors but this time when i npm start i get this error
There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix
locally.
The react-scripts package provided by Create React App requires a
dependency:
"webpack-dev-server": "3.1.14"
Don't try to install it manually: your package manager does it
automatically.
However, a different version of webpack-dev-server was detected higher up
in the tree:
C:\Users\ashraf\node_modules\webpack-dev-server (version: 3.1.9)
Manually installing incompatible versions is known to cause hard-to-debug
issues.
If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to
an .env file in your project.
That will permanently disable this message but you might encounter other
issues.
To fix the dependency tree, try following the steps below in the exact
order:
1. Delete package-lock.json (not package.json!) and/or yarn.lock in your
project folder.
2. Delete node_modules in your project folder.
3. Remove "webpack-dev-server" from dependencies and/or devDependencies in
the package.json file in your project folder.
4. Run npm install or yarn, depending on the package manager you use.
In most cases, this should be enough to fix the problem.
If this has not helped, there are a few other things you can try:
5. If you used npm, install yarn (http://yarnpkg.com/) and repeat the
above steps with it instead.
This may help because npm has known issues with package hoisting which may
get resolved in future versions.
6. Check if C:\Users\ashraf\node_modules\webpack-dev-server is outside
your project directory.
For example, you might have accidentally installed something in your home
folder.
7. Try running npm ls webpack-dev-server in your project folder.
This will tell you which other package (apart from the expected react-
scripts) installed webpack-dev-server.
If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in
your project.
That would permanently disable this preflight check in case you want to
proceed anyway.
P.S. We know this message is long but please read the steps above :-) We
hope you find them helpful!

i have tried all the steps in detail in the error log but its still not working, any thoughts on what is causing this error? Thanks in advance
It seems like you want to depend on webpack-dev-server inside your local project.
Perhaps you need to run npm install in your project, instead of your ~ home directory?
from your output, notice these lines.
However, a different version of webpack-dev-server was detected higher up
in the tree:
C:\Users\ashraf\node_modules\webpack-dev-server (version: 3.1.9)
...
6. Check if C:\Users\ashraf\node_modules\webpack-dev-server is outside
your project directory.
For example, you might have accidentally installed something in your home
folder.
so I would
cd ./my-project
npm i
Did you install webpack-dev-server on its own? It seems it has been installed either by you or by another project install. Webpack is for your local development environment so the other install is close enough to your project to interfere with the copy that react is trying to install in your project folder. Steps 1-4 in your error message should resolve your issue. If you have done that and its still not working, did you get different error messages with your next attempt to install your react package?
I have faced the same issue and this method worked for me.
Do follow the steps:
Start terminal from the desktop and write this command:
npm uninstall webpack-dev-server
This will uninstall webpack-dev-server package globally from you node modules.
Go back to you the terminal of your project and install webpack-dev-server package:
npm install webpack-dev-server#version
Note: The version part (above) should equal the versions asked for in the error message.
npm install webpack-dev-server
Now start npm:
npm start
This error mostly occurs when you have created your project using the
npx create-react-app command instead of the npm create-react-app command.
I am getting this error while installing any JS package , I have done lots of search but no luck. So please let me know where i am making mistake.
npm ERR! request to https://registry.npmjs.org/node-modules failed,
reason: error:0906D06C:PEM routines:PEM_read_bio:no start line
WebServer : Apache2(xampp)
Node : v9.3.0
NPM : 5.5.1
I think that first you need to start prompt as an administrator, then run npm cache clean -f then try to run npm install, by this command the npm will install the packages listed in package.json.
Or
You can run npm config set registry http://registry.npmjs.org/ so you can run npm install -g node-modules. Read more in this answer.
I faced the same problem and finally I was able to solve the exact above error by doing the following steps:-
check version of your npm with npm -v
run npm -g install npm#<version> This step is important as npm is getting installed globally here.
Now run the command where you want to install something globally using npm. In my Case the command was npm install -g #angular/cli#6.2.9 which worked fine after these changes
If you are still facing the problem, I would recommend to follow the instructions about installing nodejs perfectly from here https://docs.npmjs.com/try-the-latest-stable-version-of-npm#upgrading-on-windows
I am running the following:
PS D:\app> karma run
It shows the error:
[2013-11-29 17:39:54.297] [DEBUG] config - Loading config D:\app\karma.conf.js
There is no server listening on port 9876
How do I fix this?
You should use karma start command to execute karma test suite from command line.
They changed the delivery model for Karma recently
To install Karma itself, as you have already done:
npm install karma -g
But then you need to install drivers for testing frameworks. For example for QUnit
npm install karma-qunit --save-dev
Next you have to install launchers for the different browsers. For example Chrome and IE
npm install karma-ie-launcher --save-dev
npm install karma-chrome-launcher --save-dev
And now you should be good to go.
Now simply launch karma by using the start command with the config file as an input
karma start path/to/tests/karma.conf.js
