回答1:
I had the same issue. I resolved it
by excluding package-lock.json file
npm i --no-package-lock
OR by manually deleting package-lock.json
回答2:
Run npm clean cache --force and perform an install.
回答3:
I had the same issue. I resolved it by remove nodejs@10 and install nodejs@8
回答4:
Ensure that you have a package.json file within the root of your angular project which should look something similar to this.
https://github.com/heroku/node-js-sample/blob/master/package.json
If the package.json file exists, you run npm install to get the packages saved to it and that will generate a node_modules directory for you.
However, if the file does not exist, it means you have to initialize npm into the project by running npm i -y which should automatically create a package.json file for you and as well allow you to install node modules.
NB: You have npm installed on your machine already so running npm install npm -g is not ideal.

I got this error when my package.json referred to a package using file:../(local path) and the directory didn't exist. Pointing it to the correct path resolved the error.
回答6:
In my case... none of the above worked. I then deleted my package-lock.json. When I ran an npm install I got an error that a certain package could not be found in the repository. When I removed that from package.json my npm install worked!
回答7:
I had the same issue. In my case it was caused by a syntax error within the .npmrc file, which was manually edited
回答8:
On Windows 10 running npm install gave me this error.
I solved this issue by doing so from within Administrator: Command Prompt.
