I have got a Nodejs app on AppFog and want to connect to a ftp-server with this.
I did install it with npm install ftp using "Ruby Command Prompt"
This is the only code line:
var FTPClient = require('ftp');
Trying to start the app, it throws an error:
Skipping npm-support: npm-shrinkwrap.json is not provided
Which kind of server should I use or what's the problem?
Still doesn't start:
Starting Application 'test007': .
Error: Application [test007] failed to start, logs information below.
====> /logs/staging.log <====

Installing ftp#0.2.9 from local path

But no error is shown.
Thanks in advance
The quick fix is to type npm shrinkwrap, which will provide an npm-shrinkwrap file.
A shrinkwrap file fixes the exact versions of your dependencies, and the exact version of their dependencies, and so on. Without it, each usage of npm install could install different versions of the packages -- sometimes, just different bugfix versions (1.4.2 vs 1.4.3), but sometimes much greater differences. There's no guarantee that your code will work with different dependency versions (in fact it is not uncommon to break), so shrinkwrapping is a great idea for any production-level code.
If you want to 'unshrinkwrap', just delete the npm-shrinkwrap.json. You can re-shrinkwrap at any point.

I'm on windows 10
When I run:
npm run start
or
npm start
I get an error:
npm start
> app-test#0.1.0 start
> react-scripts start
'react-scripts' is not recognized as an internal or external command,
operable program or batch file.
What I already tried:
npm ci
remove node_modules and reinstall project
npm audit fix
run command from elevated PowerShell (as admin)
Uninstall Node v.18 win NVM and reinstall common Node installation LTS v.16
Check if react scripts is on dependencies section in package.json - and it's of course there.
Recreate project itself and also create a fresh new React project with npx create-react-app
Clearing npm cache
Nothing's helped me.
BUT This project runs fine WHEN I explicitly tell the node path to subfolder with a script:
app-test> node node_modules/react-scripts/scripts/start.js
Compiled successfully!
You can now view app-test in the browser.
Local: http://localhost:3000
On Your Network: http://192.168.91.1:3000
Note that the development build is not optimized.
To create a production build, use npm run build.
webpack compiled successfully
What's interesting that an old React projects also resided in the parent folder starts normally even I renew node_modules in these projects doing them npm i or npm ci
But any time I try to create and start new React app command npm start fails
UPD1: Tried to create-react-app on any other drive or folder. And it's running ok.
So culprit seems permissions policies in my common working directory ?
UPD2:
I resolved a problem though still have no clear idea who was actually the really culprit of this bug.
I copied all my parent developer folder with all code examples to another drive, then tried to create react app there and out of the blue it worked fine at then new location.
Also I removed this original folder from the drive where it used to be. And do git clone "..." at this directory< recreating the exact structure as it was before all experiments.
Then I tried create-react-app exactly at that location as I've unsuccessfully tried before swapping folders and it was OK !
Tried couple of time with different folder location within parent directory and all sill working fine now !
I remembered now I already have such bug before. And I had to reinstall Windows that time.
I also want to mention that I also have another machine with Windows, another one with Linux and had also laptop with an OSX so I can ( or could) push to this very git repository from any of these computers.
Suggestion of somebody who have any idea, why this bug was happening repeatable would be highly appreciated.
Thanks.
I'm new to js and trying to setup a simple project with express and nodemon via npm.
However, installing these packages does give me multiple errors (see below).
I am on Win 10, using the PowerShell & Atom IDE. Project is saved on Google Drive.
"Calc.js" is simply the name of my project.
I have node & npm installed and restarted pc multiple times before.
Then I set up the npm init
I begin to install the first package and get this error:
I try to install express, but get the same result, adding -g also does not make a difference. Now I install "ci", which works for some reason.
Now I have the node modules folder in my project, try to install express again, and it seems to kinda work (got the files in the node_modules folder).
However when I try to run the calc.js via "node calc.js" it
does not work.
Already tried out many things and even accidentally made it work, then tried to reproduce it and failed. Would be super happy for some help.
I am new to react-native and have found an error that makes absolutely no sense to me.
I am trying to include a calendar library: https://github.com/wix/react-native-calendars
I have included the dependency for that library in my package.json file and run npm install
The project was running fine and as expected. I have simply added one line of code to the project:
import { Calendar, CalendarList, Agenda } from 'react-native-calendars';
Nothing else. However now I am getting a red error message when the app loads on device and this is what my console is saying:
error: bundling failed: Error: While trying to resolve module xdate
from file
/Users/Alex/Documents/workspace/mobile/node_modules/react-native-calendars/src/index.js,
the package

(/Users/Alex/Documents/workspace/mobile/node_modules/xdate/src/xdate.js.
Indeed, none of these files exist:

However I have checked in the directory and in fact /Users/Alex/Documents/workspace/mobile/node_modules/xdate/src/xdate.js does exist. However I do not see any of this part: (.native||.ios.js|.native.js|.js|.ios.json|.native.json|.json)`
As to how /Users/Alex/Documents/workspace/mobile/node_modules/xdate/src/xdate.js/index can exist, that doesn't make sense because xdate.js is not a directory.
Any help?
It Usually happens if you try to install a module while your packager is open.
Try to delete node_modules folder and close the packager.
Then reinstall everything by npm install in your project directory.
First close your JavaScript bundler (Metro bundler in my case) and restart the application. This will create fresh dependency graph. This should solve the issue.
Just restart the bundler - no need to delete the Node Modules folder
I came across this issue when adding and using react-native-elements when using VS Code and Android Studio emulator on Linux Mint
In VS Code I had a terminal running Expo with Metro Bundler via 'npm start' command. After installing the react-native-elements in the folder (using 'npm install --save react-native-elements') and adding the import into the .js file I got the "However, this package itself specifies a main module field that could not be resolved" error.
In my case, this just involved a ^C in the terminal session to stop the Metro bundler and then running 'npm start' again. There was no need to delete the node modules folder at all.
If you're still getting the error even after deleting the ./node_modules folder and running npm install again, try doing the install with the --update-binary flag, i.e npm install --update-binary. This should clear out and rebuild any previously built packages on your machine.
Please don't delete the node modules folder.
The bundler has least to deal with node modules folder.
Instead close all the terminals. If using VS-code close that also.
Close all the local host server ports and if possible restart the system.
This might solve the issue.
If anyone have same issue, and remove node_module not working. Then you can try remove all node_module, package lock and using yarn to install node_module instead npm. Hope this help
None of the solutions above helped me except for restarting my MacBook. Wasted 30 minutes trying to fix this issue as I couldn't believe restarting my computer could be a solution.
I am using cheerio module for web scraping . It require htmlparser2 module , after installing htmlparser2. it gives following error-
Error: Cannot find module 'entities/lib/decode_codepoint.js'
Use this in your terminal:
npm install grunt-contrib-jshint --save-dev
Seen here:
https://www.npmjs.com/package/grunt-contrib-jshint
Below is applicable to Windows environment only, not Linux.
I received the same error when I tried to build jquery from source on Windows. It turns out that jsdom and/or grunt-contrib-jshint (both of which depend on htmlparser2) require gyp and for gyp to work you need a c++ compiler and python. I thought that I had them but turned out, that python need to be version 2.x not version 3.x. If it is 3.x it gives you a proper error on the first run (that I missed) and on subsequent runs you are getting the error in the question above which makes you wonder what's going on.
So I uninstalled python 3.x, installed python 2.x (don't forget make sure that python.exe is in your path), then deleted the node_modules folder in the project root and ran the build again.
This time around it worked. I'm not sure if this solves the OP question, but I hope it helps someone.
I am trying to reinstall node. I was screwing around a little bit trying to download a newer version.
So to uninstall I cleared out the node and node_module parts inside usr/local/bin/ and usr/local/src
Following these instructions
https://github.com/joysent/node/wiki/Installing-Node.js-via-package-manager#ubuntu-mint
When I run
xx.x#x:~/src/node-v0.10.18$ checkinstall
I get
dpkg: regarding .../node_0.10.18-1_i386.deb containing node:
nodejs conflicts with node
node (version 0.10.18-1) is to be installed.
node provides node and is to be installed.
dpkg: error processing /home/hassan/src/node-v0.10.18/node_0.10.18-1_i386.deb (--install):
conflicting packages - not installing node
Errors were encountered while processing:
/home/hassan/src/node-v0.10.18/node_0.10.18-1_i386.deb
(END)
I am not sure what else I should be doing. I tried a few other things.
:(

OH I solved it! I deleted all of the node related files through synaptic !! :D!
You may be able to use my pre-built packages which are available here:
https://launchpad.net/~chris-lea/+archive/node.js
They install a /usr/bin/nodejs binary and then create a symlink from that to /usr/bin/node.
If you are going to use these, be sure to remove any vestiges of any previous installs so that the system is using the correct binaries.
