回答1:
Step 1: Delete package-lock.json file from your project
Step 2: If your npm version is 5 and above. Then run the following command
npm cache verify
Step 3: Then run your parcel bunder
npm install -g parcel-bundler
or
npm install --save-dev parcel-bundler babel-preset-env
Hopefully it should work.

I have also faced the same issue ("Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning ETIMEDOUT: request to https://registry.npmjs.org/@angular%2fcli failed, reason: connect ETIMEDOUT 104.16.22.35:443")
Solution:
Step 1: Delete package-lock.json file from your project
Step 2: If your npm version is 5 and above. Then run the following command
npm cache verify
Step 3: Then run your parcel bunder
npm install -g parcel-bundler
Then finally, It was showing the "Network Connectivity" issue...!!!

If the answers above didn't help, please try also to run sudo npm install.
Sometimes you just don't have permission to write.
回答5:
Downgrade npm to v4.6.1.
npm install npm@4
Version >= 5 is unstable.

Step 1: Try to clear the cache first using
npm cache clear --force
Step 2: Try to install again
npm install -g @angular/cli
