I have a working react app that I had hosted on a linux environment, but the client has switched their hosting provider and now I have to run the app on a Windows environment. I personally am unfamiliar with Windows and having some serious issues getting my app to work now.
After loads of debugging and testing I now can get my app to run, but when I start it, it will throw some errors which will results in a broken app in the browser.
So when I run npm start it will start up the app and spit out this error:
Screenshot of the terminal error 1/2
Screenshot of the terminal error 2/2
It seems to spit out some complaints when using npm run watchJS which runs this command babel src --watch --out-dir lib.
I am completely lost at this point and have no idea where to go from here.
I can provide as much detail as anyone needs after looking at the question, I just don't know what else to add to this issue and don't want to fill up this question with irrelevant info.
Thanks in advance for any help
It is likely a bug with the version of npm you are using.
See this thread:
https://github.com/npm/npm/issues/18380
Try rolling back your version of npm to 5.3
The issue appears to be exclusive to windows with babel packages.

Hello i am not really sure how to explain my problem or how to ask for help.
But am going to try it anyway lately when i create a react app it installs like normal.
But from the moment i use npm start i get this error (npm start error terminal).
Which says it has nothing wrong with node js/npm so i suspected it was something about the react app dependency that was wrong. When i downgrade to a older version of react scripts it works but the newest version 16.13.1 doesn't work even tho i use this version of react on my windows laptop. In case it helps to solve my issue here is the error log that npm generates (error log npm) i hope this helps to solve my issue
I have found the solution for my problem by setting the path value for system32.
You can do this by the following steps
Goto > Control Panel\System and Security\System\Advance system setting\Enviroment variable and set system variables path C:\Windows\System32\ variable and restart your System.
After i have done these steps it seems to work
I am not sure where to start looking for the issue here.
I recently updated from angular 5 to angular 8. The application runs fine after the update. I don't know if this is related.
All of the sudden, my Node JS scripts stop seemingly at random. Sometimes they run, usually they don't. This is any script.
By "Stopping" I mean the console, mid execution, leaves the last line it wrote up, and on the next line, I am able to write more commands.
Example:
C:\location\> npm start
ng serve --aot
** Angular Live development server is listening on .....*
12 % building 22/23 modules 1 active ...somefile.ts
C:\location\>
There is no error, even when I run --verbose. Also, if I have multiple windows up or multiple servers running, they all stop at the same time. It is happening regardless of the application or package, including http-server, Angular, and installing dependencies.
I couldn't find anything related online. Has anyone ever seen this?
Update:
The issue is caused by my lack of CPU.
I thought I fixed it by updating, but that didn't work.
----------- (previous reply, not a solution)
It appears some of my installed dependency versions conflicted with package.json. Basically something did not fully update as expected.
I resolved the issue by running npm install.
We have two instances of our Node-Express app: one for development, and one for production. We are implementing PM2 process manager. This is for a Windows Server 2012 environment.
For some baffling reason, PM2 (with pm2-windows-service) worked fine when set up in our dev environment, but won't even run node in our Prod environment. What could be the cause?
Log files reveal nothing helpful
If you look at my related question, you can see that PM2 appears to be launching node, but is not (or it instantly crashes).
All we can conclude is there is some difference in settings between these two servers. Any clue what difference in settings might be causing PM2 to fail like this?
This is related to a more specific question I have out there about issues we're having implementing PM2.
Thank you!
Ok, I got the answer after posting an issue to the pm2 github issues page.
Sharing it here in case anyone else finds themselves in this situation:
https://github.com/Unitech/pm2/issues/4113
(basically pm2 3.2.5 introduced a bug that causes this issue in Windows. My QA install was 3.2.4. The issue was resolved by reverting to 3.2.4. Simple process, see instructions at link above.)
It may be not really pm2 issue, bit more npm. On the server where pm2 doesn't work please try that command in PowerShell:
Get-Command pm2
Does it return the correct version(not 0.0.0)? If not, there is an issue diring installing that package, so as an option it's possible to install that manually. Also we asked familiar question in that ticket last month:
https://github.com/Unitech/pm2/issues/3964
Like it described in a ticket above you can try to check other npm package with familiar issues:
npm install mocha -g
And that try to reach mocha-cli
I am in progress of making a simple Electron app. When I boot the app from the console on my Win10 PC (using the classic npm i && npm start), it boots the modules and works like a charm. When I bring it to an iMac running High Sierra for testing for its deployment, it crashes when I try to use the app with the error of Cannot find module {insert module here}. I've tried clearing the cache (recommended here), but it has been to no avail. I have my package.json, index.js, and downloader.js all linked below for ease.
Edit: Sorry for not linking before! The repo is here (it's pretty easy to find the package.json and index.js, the downloader.js is in the js/)
I'm open to any and all help! Thanks in advance for, like I said, any and all help!
I have a project from other developer and I try to add to it few components. But I still cannot run it.
I've installed all dependences using yarn install, than I've executed npm run dev and when I execute npm run hot, there aren't any error in console on my localhost:8081, I see clear white screen.
Can you help me please, give me an idea where to look for a problem? Thank you.
It was amazing stupid error. I have XAMPP installed on my PC and Tomcat works on port 8080, so npm run hot started server on 8081, but additional javascripts was loaded from 8080. ...
It wasn't only one reason, I don't remember how it becames to show me those js-files. First, they wasn't called from script any time.
