React-native removed when use npm install

Question

I don't understand why my npm make that and i'm new with react-native.

Here is the description of my "bug" on Windows 10 :

I can use react-native command for run android or create react-native app like that react-native init TestApp

When i go into my app folder with cd TestApp and i run react-native link or other react-native command everythings work fine.

But if i install a new package like fbsdk with npm like that npm install react-native-fbsdk --save i saw after installation this message :

added 1 package and removed 639 packages in 22.207s

And after that, if i would like use react-native command i have this message :

Command link unrecognized. Make sure that you have run npm install and that you are inside a react-native project.

For this message, i have entered react-native link command.

You know why npm remove all my packages ?

Are you using npm 5 ? As per the [documentation](http://blog.npmjs.org/post/161081169345/v500), `npm install` will save it automatically to a `package-lock.json` file. — Val Berthe, Jun 07 '17 at 16:51
@Ksyqo yes i use npm 5. I have see a package-lock.json. It's possible symlink is the problem. — Shinix, Jun 07 '17 at 16:57
It seems like dropping a `npm install` erases the content of `package-lock.json`. Try to install without the `--save` flag. — Val Berthe, Jun 07 '17 at 16:59
This issue made me start using yarn instead of npm. It looks like the issue started when I upgraded to npm 5. — Nicolas Meienberger, Jun 14 '17 at 15:05

I got the same problem.

However I solved the problem by deleting the package-lock.json and then running npm install.

Using npm 5.0.3, removing the package-lock file seems to work for me too – gianni Jun 24 '17 at 16:01

I also noticed recently that npm install doesn't do what I expect, but that may be because I'm newbie.

However yarn install is a good replacement and is working fine for me. I used it to upgrade/downgrade things by directly editing packages.json, and it also solved the npm link problem that I faced.

Edit: downgrading to npm 7 solved all my issues
