I've been having this problem recently that nothing related to npm is working for me except npm start.

npm install is giving this error:

$ npm install @material-ui/core
npm ERR! Object for dependency "@babel/generator" is empty.
npm ERR! Something went wrong. Regenerate the package-lock.json with "npm install".
npm ERR! If using a shrinkwrap, regenerate with "npm shrinkwrap".

First of all you need to make sure that your node and npm versions are up to date. if not please upgrade your node and npm packages to latest versions.

nvm install 12.18.3 // update node version through node version manager

npm install npm // update your npm version to latest

Delete your node_modules folder, package-lock.json and yarn file (if you have).

Force clean the entire NPM cache by using following and.

npm cache clean --force

Re-Install all the dependencies.

npm install

If above step didn't resolve your problem, try to uninstall yarn globally by delete the Yarn folder from global folder and then run.

npm uninstall -g yarn 

I met this problem after I tried to delete node_module unseccessfully. It didn't let me delete the rest of that directory, even part of it. from the file explirer I tried to delete, to remove - with no help So I renamed the directory (this is the only action left to do..) and then ran npm install that fixed the problem
