Permission denied error on npm start

[sojharo]

I cloned the application and then after installing all the dependencies, I got following error when I tried to run the application using "npm start" command.

Looks like you have a problem in your npm installation. Did all went well with npm install?

[cassiozen]

Hi @sojharo. I'll close this for inactivity, but if you're still having problems please feel free to reopen it.

Hi, I have the same issue, I cloned the repository from my GitHub account, it works on Window, not in Linux

It's weird, I have another repository on the same machine and it does works...

[cassiozen]

Hi @Rolando-Barbella It's really weird. Have you tried installing webpack and webpack-dev-server globally? npm install -g webpack webpack-dev-server

[Rolando-Barbella]

Hi @cassiozen , Thanks for the answer, I pretty much rewrote the webpack-config.js file, deleted the node_modules folder, installed the dependencies again and it works, is something to do with webpack I think

[dloret]

Hi, I got this issue also in this precise configuration:

• I created the project repo in my dropbox, on Windows 10 (professional) laptop
• I installed the npm dependencies and created package.json + webpack.config.js on Windows 10
• I loaded the project on Visual Studio Code on Linux and ran "npm start" from Fedora 25 (personal laptop)

It could be related to the fact the config (global versus local) installation of some packages is not the same in the 2 environments (windows vs linux). After simply deleting the node_modules folder, without changing the config files, everything was back to normal again.

[martin-martin]

Had the same issue. Simply deleting /node_modules and running npm install again resolved it.

[russellsean]

I get this error a lot using Vagrant, rsync includes /node_modulesif it already exists on the host machine. @martin-martin is correct, delete it from the guest machine and run npm install

[mclovinxie]

I have the same issue like this: sh: 1: webpack: Permission denied npm ERR! code ELIFECYCLE npm ERR! errno 126 I solved this problem by chmoding node_modules/.bin/webpack: sudo chmod 777 ./node_modules/.bin/webpack

Hi, same issue. What i do : npm init react-app my-app ---> npm start ---> ok npx create-react-app todo-list ---> npm start ---> error ELIFECYCLE

I deleted todo-list, and retry with : npm init react-app my-list ---> npm start ---> error ELIFECYCLE

Did i break something ? my-app is still working

in my case i update file scss-->vendor--> _variables.scss i change the line:

@import "node_modules/@coreui/coreui/scss/bootstrap-variables";

to

@import "node_modules/@coreui/coreui/scss/variables";

and than i delete my node_module and run : yarn install yarn start

*i recommend u to using yarn

[YanCallier]

Thanks R1zZ, Yes I solved it when I delete my node_module and run npm install to re-built it. I guess I would see the benefits of yarn in time

Hi @Rolando-Barbella It's really weird. Have you tried installing webpack and webpack-dev-server globally? npm install -g webpack webpack-dev-server

This solved my issue, no other operation needed in my case!

[limeandcoconut]

Not helpful for those of us who aren't planning on npm i -g webpack and other deps though 😕

if u have the same problem in the discussion,u just change css style on folder css in react project ..

[yashmalik23]

All you need to do is delete the node_modules folder and run npm install

[epiphanizer]

chmod recursively helped in my scenario, where npm installing again caused a problem. I ran into this while dealing with an old artifact and pulling its node modules over.
