This is the error
events.js:160
throw er; // Unhandled 'error' event

I don't get why this error is happening, I've been working on this project for a while and now only with this project is giving to me this error, I've tested with other project that I had made and it serves OK, I've read about ENOENT but I don't get why I have to add code on my project if NEVER I've changed libraries or something.
Note: I'm runing a Windows 10
I solved this issue by:
1. clearing npm cache , run the following commands:
npm cache clean -f
npm install npm -g
Then:
2. catch the exceptions on your code, it also thrown when there is un-catched exceptions.

I'm trying to start a React application, with npm but I get this error:

I'm using node version 10.16.3 and npm 6.13.6. I've cleaned npm cache and install npm again, but I'm getting always the same error
I suggest doing these three steps:
npm install -g npm#latest to update npm because it is sometimes buggy.
rm -rf node_modules to remove the existing modules.
npm install to re-install the project dependencies.
the problem is fixed , i've installed another version of "react-scripts" , because the actuel version is not stable , so i use to overwrite it with the given version, so use this command to install :
npm install react-scripts#2.1.8
Once the installation is completed your can run your reac app :
npm start

I have tried clearing the npm cache, rebooting, and nothing seems to work.
There seem to be two versions of node.js installed:
node -v ==> v10.15.3
nodejs -v ==> v11.15.0
Both these versions are probably the result of trying to upgrade node.js to a newer version than what comes with Ubuntu, though I don't know why or how. I upgraded following the instructions on this webpage - https://github.com/nodesource/distributions:
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs
When that didn't work I tried again with vers 11.x.
My version of npm is: 6.9.0
Why are there two versions of node.js? Could this be the problem?
What should I do to get npm start to work? If clearing everything and starting over is the best approach, I am all for it. This is my first time using node.js, so I am totally lost here. BTW, downloaded electron apps (e.g. VS Code) seem to be working just fine if that's any help.
Solution 1: Try to find the exacly npm/node version your project are using to install.
Better use a npm version manager like nvm.
Solution 2: On linux bash execute:
sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p
The reason?
the OS have a max handle files count. You need to increase this.
Why?
did you realize how many files the node_modules folder has on the smallest/simplest project you have? Now, try to imagine on medium/large project.
NPM start throwing the following error
events.js:160
throw er; // Unhandled 'error' event

Error: Error watching file for changes: EMFILE

I have tried
rm -rf node-modules/
npm install
npm run build
but the error still occurs.
This looks to be a similar issue with the same solution as that for which I answered here
You have to install watchman with brew install watchman.

How do I fix this?
This should be fixed in React Native CLI 0.1.9. To update your CLI:
npm uninstall -g react-native-cli
npm install -g react-native-cli
There was a regression in 0.1.8, reported here: https://github.com/facebook/react-native/issues/5169
Check if the gradlew.bat file is present in the android folder if it is not there then simply copy gradlew.bat file from another project.
react-native-cli#0.1.8 error
Rollback react-native-cli#0.1.7
everything is ok.
To fix this, Reinstall NodeJS https://nodejs.org/en/
Then
npm install -g react-native-cli --vebrose
react-native init App --verbose
If it still fails, try installing Python 3 https://www.python.org/ and repeat the process.
When I run the hello example from SpookyJS, it fails with the following error:
$ node examples/hello.js
events.js:72
throw er; // Unhandled 'error' event

Error: spawn ENOENT
at errnoException (child_process.js:998:11)
at Process.ChildProcess._handle.onexit (child_process.js:789:34)
In fact, all examples that I tried result in this error. I'm stuck, as I cannot interpret the error message even when looking into the source code. Do you have any ideas?

Solution: npm install -g casperjs
I assumed that it is enough to call npm install locally, but casperjs must be in the path. After I installed casperjs globally, the example worked fine.
