为什么安装 npm 包会重新安装我所有的其他包？

Question

I have this annoying issue where when I try to install a new package with npm it starts installing all my other packages, often breaking something and forcing me to reinstall my node modules. What could be the problem and how could I fix this?

Answer 1

It does not install all your other packages, what it does is it just installs all the dependencies in order to actually install the gatsby-source-contentful .

You can see the dependencies of the package in the dependencies tab. Of course, those dependencies might have more dependencies so it's just a chain of installations and updates.

For example the gatsby-source-contentful package, there is a dependency called gatsby-source-filesystem which has a dependency on the file-type so that's why it tries to update that.
