Npm removes packages (a lot)

[maieonbrix]

I'm opening this issue because:

• npm is crashing.
• npm is producing an incorrect install.
• npm is doing something I don't understand.
• Other (see below for feature requests):

What's going wrong?

I encounter this bug only when I develop using react-native. When I use the cli to init a new project (react-native init) everythings works fine, and then, every single time when I try to install a new dependency using npm here is its output :

added 2 packages, removed 652 packages and updated 11 packages in 5.944s

How can the CLI team reproduce the problem?

Use the react-native-cli@2.0.1

• react-native init test
• cd test/
• npm install --save react-native-fetch-blob

supporting information:

• npm -v prints: 5.2.0
• node -v prints: 8.1.2
• npm config get registry prints: https://registry.npmjs.org/
• Windows, OS X/macOS, or Linux?: macOs
• Network issues:
  • Geographic location where npm was run:
  • I use a proxy to connect to the npm registry.
  • I use a proxy to connect to the web.
  • I use a proxy when downloading Git repos.
  • I access the npm registry via a VPN
  • I don't use a proxy, but have limited or unreliable internet access.
• Container:
  • I develop using Vagrant on Windows.
  • I develop using Vagrant on OS X or Linux.
  • I develop / deploy using Docker.
  • I deploy to a PaaS (Triton, Heroku).

Thanks for your great work !
