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?

When installing modules in a freshly cloned git repo using npm install on npm version 5.0.0, I get the weird behavior of the node_modules folder having the wrong owner. Using ls -la I can see the following info is returned:

drwxr-xr-x 372  502 dialout 12288 May 28 11:16 node_modules/

When starting the application, I get several dependency errors. When installing the dependency that is reported to be missing, another entry appears.

When doing the same using npm at version 4.6.1, I get the following output:

drwxr-xr-x 373 root root 12288 May 28 11:19 node_modules/

Which is expected behavior, and no packages are missing

Note: The missing dependencies seem to be devDependencies from a few of the packages I depend on. There is something mentioned in the Breaking changes section of the NPM update changelog, but not about these packages not being installed when running npm install

How can the CLI team reproduce the problem?

npm install -g [email protected]
cd /path/to/your/repo
npm install
ls -la

There is no npm-debug.log file, as there are no errors reported.

I'm positive I'm running npm as root:root.

root@node1:~# whoami
root
root@node1:~# groups
root
