As you can see from the log, it was able to load until zone.js. If failed upon loading opn@4.0.2. Why is opn blocked? Beeing a Nodejs package, it should have only Javascript files.


I’m unable to reproduce this (opn downloads and installs just fine for me). Is it possible that you’re using a corporate proxy that’s doing the blocking? I would note that it includes a rather large shell script, in addition to the JS.


Yes, when I try to download the opn zip file from github (https://github.com/sindresorhus/opn/archive/master.zip), I get the following error:

It seems that the coporate proxy blocks shell scripts.
