npm start 和 npm run build 因 npm ERR 失败！ 代码生命周期

Question

I have had this issue for 3 days now. I used to get this error occasionally and it would just start working after a few troubleshooting commands, now npm start is not working at all and I keep getting this error.

Host Details:

Ubuntu server 18.04 LTS
Node v8.10.0
npm 6.10.2

I have tried the following in this order:

rm -rf node_modules
rm package-lock.json
npm install -g npm
npm install
npm start
sudo npm start

Then:

npm install create-react-app
npm install react-scripts
node node_modules/react-scripts/scripts/start.js

Also tried deleting the entire folder, making the directory and pulling from github again. Just to try it chown ubuntu project_folder

Nothing is working.

The app was created using create-react-app and it works fine on my desktop and my laptop.

Starting the development server...

The build failed because the process exited too early. This probably means the system ran out of memory or someone called `k
ill -9` on the process.

Any help is greatly appreciated.

Answer 1

I have had this error many times. After npm install create-react-app , check if create-react-app has been installed with the command create-react-app . It will show you that create-react-app has not been installed because you are not installing create-react-app on the folder where your project is. You just have to install create-react-app in right directory . Or you can install it globally with

npm install -g create-react-app

If you don't want to install it globally, go to the folder where your project is and then install create-react-app in that folder.

Basically, you are getting this error because create-react-app is not installed on your directory. This should fix your problem.

If this does not help, you can do the following:

Note: You'll need to have Node >= 8.10 and npm >= 5.6 on your machine. Go to a desired folder. Then,

ngx create-react-app my-app
cd my-app
npm start

This is in the official documentation of create react app, So, this should work.

Thanks everyone for the replies. Looks like user error.

updated nodejs following this thread: How do I update Node.js?

and the project loads just fine, I guess with Arch being on the bleeding edge of software and the ubuntu repos being behind got to me.
