Webpack-dev-server: Permission denied, WTF???

Question

Node.js

Hello people)
Code at work and at home. Code on an external drive.
Once again I come home and continue to progat. But not at this time.
This time I was visited by the next misfortune.
I run webpack-dev-server and it throws an error:

I think: "Well lan, right now I'll write chmod 775 . -R" - Didn't help Oo
Then I deleted node_modules and npm cache clear && npm i - didn't help either. Ooooh
what kind of magic is that? How to solve this problem?
З,Ы, The disk is completely rw for the user.

Answer 1

I deleted the node_modules folder, then did npm install again and when I ran webpack ( npm run dev ) everything started fine, no error

Answer 2

Perhaps this problem is with mounting the disk (it was mounted without execution rights). Find your device in the list via the "mount" command and check the execution permissions (exec). Try to mount manually with mount -o exec
For other cases, you need to find where the webpack-dev-server file is launched from.
- To install webpack-dev-server locally (without the -g flag), go to the ./node_modules/.bin folder and make sure the folder contains file links and not executables. Find where the webpack-dev-server file is referenced (probably ./node_modules/webpack-dev-server/bin/webpack-dev-server.js) and set permissions to 0755 on this file. If instead of links there are executable files, then most likely the folder was moved from another location. Delete the entire ./node_modules folder and re-install the packages (npm install).
- To install globally, look for webpack-dev-server in ~/.npm/.bin and also set the appropriate permissions
- When running through webpack-dev, find its location (which webpack-dev), open it in a text editor and try to find the folder from where the webpack-dev-server file is launched
