Installation hangs on MacOS

I am on MacOS 10.13.4. Here are my settings.

• npm 6.0.1
• node 10.0.0
• python 3.6.4
• conda 4.5.3
• pip 10.0.1
• jupyter 4.4.0 (from jupyter --version)
• jupyter 1.0.0 (from pip list | grep jupyter)
• jupyterlab 0.32.1 (pip list)

I followed the installation instructions jupyter labextension install jupyterlab-drawio and the for development (clone the repository, then npm install, ....). However, I seem to always get stuck on downloading or processing some tgz file. I have no idea what this file is. Using the dev installation method, which I thought would avoid downloading anything since I think it's building from source, it hangs here

If I hit ctrl-c to break out of this, then I see the following, which is not helpful either.

I cleared the pip and npm caches.

• rm -fr ~/Library/Caches/pip/wheels
• rm -fr ~/Library/Caches/pip/http
• npm cache clean --force

None of this helped.

Any ideas on what's going wrong here?

I've had the same issue on Ubuntu where it gets stuck in the same step. Using Node 8 instead of Node 10 fixes it, possibly due to this issue: https://github.com/jupyterlab/jupyterlab/issues/4585

Same issue here:

$…  sudo jupyter labextension install jupyterlab-drawio                                                                                                                                                                                                                                                                                                                                                                  15.4m < Wed May 30 17:33:54 2018
