npm package seems to be corrupted

Question

I am getting these warnings and then errors at the end. What is the fix?

npm WARN deprecated [email protected]: core-js@<3.0 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.
npm WARN deprecated [email protected]: One of your dependencies needs to upgrade to fsevents v2: 1) Proper nodejs v10+ support 2) No more fetching binaries from AWS, smaller package size

Solution 1

Try removing package-lock.json and then npm install. This worked for me:

cd <your-project-directory>
rm package-lock.json
npm install 

Solution 2

1. Remove package-lock.json

2. Remove node_modules,

3. and then install packages using npm install.

This resolved issue for me.

Solution 3

You need to disable your antivirus software and run cmd as an administrator. Don't forget disabling the windows firewall. As for the deprecated Core-js 2.6.10 I'm facing the exact same issue but at least it's a warning you can ignore. I've tried reinstalling Angular cli and manually updating Core-js to the latest version using npm install -g core-js@latest unfortunately neither worked. Also fsevents seems to be Mac related and nothing to worry about.
