I set up my project with the Express generator and everything was fine when creating the repository on GitHub and I was able to clone it to my desktop and generate the folder structure. When I did a lot of work on my app (Pug, node, express) I wanted to add all the files in my project with "git add ." and I get this error in my console:
error: open("node_modules/.bin/acorn"): Invaliid argument
error: unable to index file node_modules/.bin/ac/acorn
fatal: updating files failed
As I can't add the files I can't commit or push them either.
I'm running windows 10.
edit: If I try to move the files to a new file in windows explorer I get this error https://snag.gy/T1dI3M.jpg so I guess it's something to do with the acorn package but I don't know if I can delete it.
It is recommended that "node_modules" must be kept in ".gitignore" file. So that while performing push operation node_modules folder will get ignored and updated to git.
