I suggest you to use Long Path Tool Program to solve your problem.

What npm version do you run? Since v3 this shouldn't be a problem because of a flat installation. If this is installed with an older version, delete the top node_modules folder and run npm i again.

Yes, node and windows have this little issue with paths.

At first, IDK why you want to copy the folder including node_modules , is better to only copy YOUR files and your package.json file and do a npm install in your new folder.

In any case, I have a similar issue trying to delete completely de node_modules folder and reinstall all dependencies again; this for I created this simple PowerShell script to do it. It uses windows robocopy.aspx). You can modify it to instead of replacing the node_modules folder, you copy all your project to other location. If you don't use PowerShell this .bat file is for you.

Let me know if it works!
