I have a monorepo using Lerna that I trying to build with Gitlab CI. Running lerna run build locally builds everything successfully.
The Dockerfile that Gitlab tries to execute looks a bit like this:
FROM node:16 AS common
WORKDIR /usr/src/app
RUN yarn global add lerna
COPY . .
RUN lerna bootstrap --include-dependencies
RUN lerna link
RUN yarn
# yarn build === lerna run build
RUN yarn build
Which results in the following errors:
Cannot find module '#project/common' or its corresponding type declarations.
import { SomeClass } from '#project/common';
Is there any step I am missing? Thanks in advance!
What version of lerna is being used locally? Amend your question to include the output of learna info.
yarn global add learna will install the latest version, which currently is v4.0.0.
I was able to fix this issue by changing the Dockerfile. Running yarn before running lerna bootstrap and removing yarn build resolved the errors.
My Dockerfile now looks like this:
FROM node:16 AS common
WORKDIR /usr/src/app
RUN yarn global add lerna
COPY . .
RUN yarn
RUN lerna bootstrap --include-dependencies
I can definitely attribute the errors to my limited knowledge of Lerna, but I hope this answer can still help others with similar issues.

I have a project that I am using yarn for. I've installed all my packages using yarn, I run yarn dev and so on. Now I'm following a tutorial that requires me to use npx to set up a package. - I'm wondering if I can just go ahead with this or if I will end up mixing things up here, as npx, as far as I know, is related to npm ?
Yes. npx will run the executable from your node_modules directory if it is installed there. If it is not, it will install the executable into a different location. It will not interfere with yarn operations.
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 tried to run npm install and npm start but both does not work. I reinstalled the nodejs but still the same. How to resolve it?
If you're trying to install the dependencies of an existing project (which the context implies), you need to run the command npm install in the directory where the package.json file of the project is.
If you've created a new and empty project folder, you need to first run npm init to create a package.json file which is used to manage the dependencies of your project.
Are you sure you're in the head directory? For example, if your project is in:
$ Documents/Projects/JS-Projects/Work/Client-Management-App/
Then that's the folder you need to be in: the Client-Management-App/ directory, because that's where the package.json file and the /node_modules/ folder will be created.
Also, have you run npm init? That might be another reason why.
I'm new and I need to use node for off-line use so, I'm trying to understand how the install modules work.
It's the same if I use npm install express or included it in the package.json?
The way a package is installed will be the same whether you manually type npm install express or put it in your package.json and then do npm install. The difference comes when you try to install your Node project elsewhere.
For example, if your code was checked into GitHub and you didn't include a package.json with all of the dependencies listed, then when the project was downloaded you would have to manually re-install all of the dependencies on the command line in order for it to work. But if you had checked in a package.json with the code, then you could run npm install to install all of the dependencies at once, and not have to remember which ones were necessary.
In addition, the package.json allows you to specify an "approximate version" of a dependency to use. This way if a few packages in your project share a dependency and they all specify similar "approximate versions", only one version will be installed and it will be shared between packages. This saves some install time.
Nothing actually. But you don't want to do that again and again. So you might as well put your module dependencies in your package.json
