To Solve npm ERR! code ELIFECYCLE Error You Just need to Clean cache and Node_module and some other stuff inorder to resolve this error. First of all Just clean cache with this command: npm cache clean –force Then, Delete node_modules folder from your project. Now, Just delete package-lock.
To solve the Missing script: "start" error, make sure to add a start command to the scripts object in your package. json file and open your shell or IDE in the root directory of your project before running the npm start command.
It's basically saying it fails to spawn your process not due to permission but to an error in your script. Source
You don't have any problem executing NODE_ENV=production node app.js ?
One might think this is because outdated versions of npm and node, but it's not the case.
Just as Pierre Inglebert says, if you look into the source you can see that End of lifecycle means the program unexpectedly stopped. This can have various reasons. So it's not a syntax error and not an expected exception/error.
The error appeared to me when a different tool was already using the http port (3000) defined in my node scripts. When you run your node app on port 80, make sure you have stopped Apache webserver (as an example).
In my case, it was because of low RAM memory, when a photo compression library was unable to process bigger photos.
While working on a WordPress theme, I got the same ELIFECYCLE error with slightly different output:
npm ERR! Darwin 14.5.0 npm ERR! argv "/usr/local/Cellar/node/7.6.0/bin/node" "/usr/local/bin/npm" "install" npm ERR! node v7.6.0 npm ERR! npm v3.7.3 npm ERR! code ELIFECYCLE npm ERR! [email protected] postinstall: `bower install && gulp build` npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the [email protected] postinstall script 'bower install && gulp build'. npm ERR! Make sure you have the latest version of node.js and npm installed. npm ERR! If you do, this is most likely a problem with the foundationsix package, npm ERR! not with npm itself. npm ERR! Tell the author that this fails on your system: npm ERR! bower install && gulp build
After trying npm install one more time with the same result, I tried bower install. When that was successful I tried gulp build and that also worked.
Everything is working just fine now. No idea why running each command separately worked when && failed but maybe someone else will find this answer useful.
If you came here like I did, after receiving a similar error when trying the React Getting Started guide, you might like to know that the problem could have been caused by not having installed Watchman. Download it here, or install it with Homebrew with brew install watchman and try again: https://facebook.github.io/watchman/docs/install.html
PS: You might want to do a brew update first.
