I am trying to build my react and node.js web app but fail to build ever since fixing packages.
i get the following error
Module not found: Error: Can't resolve 'fs' in 'my-app/node_modules/dotenv/lib'
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! my-app#0.1.0 build: `react-scripts build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the my-app#0.1.0 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
I have tried to clear the cache of node_modules, remove package-lock.json, re install with npm and re-build, but nothing works.
Does anyone know how to solve this please?
Node Core Modules like fs won't work in the browser because they require binaries that aren't present in the browser. It apparently has been stubbed out of create-react-app, as per this Github issue.
The web doesn't have a filesystem, so it makes sense it won't ever work. Unfortunately for you, it means you should find a workaround. What were you trying to achieve with fs ?
This may be a short hand fix, but i removed the dotenv package and loaded my env variables into the Azure config variables.
I am new to react-native and whenever I try to write a command relating to npm, it returns an error (usually one that says EISDIR). I have tried looking at the answers to similar questions of mine, but am confused by the jargon about PATHS and issues with directories.
I have tried uninstalling and reinstalling node, and still when inputting npx create-react-app my-app it returns something along the lines of this:
npm ERR! code EISDIR
npm ERR! syscall read
npm ERR! errno -21
npm ERR! EISDIR: illegal operation on a directory, read
npm ERR! A complete log of this run can be found in:
npm ERR!
/Users/username/.npm/_logs/2021-08-03T20_29_31_976Z-debug.log

Can someone explain a solution in a simple way for this? Please ask questions for more information if I left something out.
Thank you!
I've been using create-react-app without issues for some time, but recently, after running it, I cannot start the development server. After running npm start, I get the following error:
sh: react-scripts: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! js-calculator#0.1.0 start: `react-scripts start`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the js-calculator#0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
Scripts appear to be in the correct location and correctly configured in the package.json file.
Also, npm start throws me the same error if I run it in other react-apps folders that used to work before.
I tried various suggestions I found here on stackoverflow:
installing create-react-app globally;
reinstalling dependencies (npm install);
reinstalling react scripts (npm install react-scripts --save);
updating node and npm;
but none of the above worked.
Any suggestions?
I've also a more detailed .log file, in case anyone wants to have a look at it.
After many tries and more reading of related issues here on SO, I found the cause. One of my react-app parent folders (five levels above) name was "example/example"; naming it to "example-example" solved the problem.
I've gotten this same error on two different npm packages and haven't seemed to be able to figure it out. I've checked this answer and I don't have any other servers running. I've also tried deleting my module_packages folder, cleaning npm cache clean and then reinstalling using npm i as many threads have suggested, but I still get the same error.

Any ideas on what might be causing the error would be helpful.
I have good and bad news for you. The good news first: Everythings fine with your computer.
The bad news: The module you would like to install is incompatible with windows operating systems. Have a look at the first line of your error message:
Unable to download libstorj for platform: win32 and arch: x64
There is already an open issue for this problem on GitHub, see: https://github.com/Storj/node-libstorj/issues/43
As mentioned in this issue there are multiple problems:
download/unzip not working
not compiling because some linux-only functions being used (access function)
not linking (it seems nettle and some other link fails)
So you have two options: Wait until this issue gets fixed - or - switch your operating system ;-)
I was getting a "code ELIFECYCLE" error trying to run "usemin" and "imagemin" node-modules via script entries in package.json. These script entries were given in a Coursera "Full Stack Developer" course:
"imagemin": "imagemin img/* -o dist/img/ &&
"usemin": "usemin index.html -d dist -o dist/index.html",
The first line should have read:
"imagemin": "imagemin --out-dir=dist/img/ img/**/*.{png,jpg,git}"
And the issue with usemin giving a "code ELIFECYLE" error was finally traced to the fact that I had installed the API version ("npm install usemin") rather than the cli version ("npm install usemin-cli).
Hope the above helps some other nubbie avoid what now look like an obvious pair of mistakes!
What does ELIFECYCLE mean?
Here's my app code: https://gist.github.com/samholmes/388ca4552c5936b52c5d
When I run the 'blast-emails' command, it will run for a while until shortly crashing with the error:

I'm looking for one of two answers: What does ELIFECYCLE mean? (or) Why am I getting the error in my application code?
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! 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.
When running Webpack build I was getting similar error because node doesn't understand async await keywords on older versions. I added webpack babel-plugin-transform-async-to-generator and it was solved. This replaces them with promises.

I have the same issue here is how I got solved finally!

I was using mlab for my database and under the file .env i forget to properly put the user name and password. When I correct that I works.

So it might be good to look any data connection we made in our code if we have.
I had the same error after I installed new packages or updated them:
...
npm ERR! code ELIFECYCLE
npm ERR! errno 1
...
It helped me to run installation command once again or a couple of times.
After that, the error disappeared.
I had this issue when I was running two projects that had the same set up and I already had one running. This meant that the other project couldn't use that port number. As soon as I stopped the other project running I had no issues.
This issue can also occur when you pull code from git and not yet installed node modules "npm install".
The Windows solution is the same as the Linux sudo answer. Run the npm start (or whatever) as Administrator. I had added a new module to my project. Worked on some machines but on others that were more locked down, not so much. Took a while to figure it out but the new module needed access to "something" that wasn't available without administrator permissions.
I had the same error code when I was running npm run build inside node docker container.
Locally it was working while inside a container I had set option to throw error when there is a warning during compilation while locally it wasn't set. So this error can mean anything that is connected with stopping the process being done by NPM
In my case I generated a similar error when I copied the project over from another directory. some hidden files, like the critical .babelrc, were missing. SO ahhh... make sure you copy all the files!
:)
For me it was a ternary statement:
It was complaining about this line in particular, about the semicolon:
let num_coin = val.num_coin ? val.num_coin || 2;
I changed it to:
let num_coin = val.num_coin || 2;
Likewise, I saw this error as a result of too little RAM. I cranked up the RAM on the VM and the error disappeared.
I found the solution here - https://javahowtos.com/guides/124-docker/418-npm-exit-status-137-when-building-a-docker-image.html
It says - The cause of this specific npm error status usually means that Docker is going out of memory. So, when this happens, the Linux kernel just kills the process.
if you are running on ubuntu, please check your nodejs version. please update the version to the latest and clear the cache and reinstall the modules (npm install) and build.
or otherwise
please upgrade your RAM size and try again. it'll work sure.
First, you will have to remove the npm cache and upgrade to the latest version of the node and npm will resolve the issue.
sudo npm cache clean -f
sudo npm install -g n install n
sudo n stable
The first command will force clean the npm package manager's cache, After the second and third commands, a stable version of the node and npm will be installed. then you can execute npm i and npm run build for creating an optimized production build.
This solution worked for the same error on the npm run build command in nextjs.
