wskdebug cannot install on mac os mojave

[tania-m]

I tried to install wskdebug on mac os mojave (with root privileges) using node version 12.

The installation keeps failing with following errors:

/usr/local/bin/wskdebug -> /usr/local/lib/node_modules/@adobe/wskdebug/index.js

It seems strange to me that accesses are missing. Any idea what could really go wrong?
Do I need to install ngrok locally as pre-requisite? If so, where?

Your local user might not have full write permissions on /usr/local/node_modules. I and others have seen this before on osx or also in containers. Seems like a general issue with global npm installs, if the OS or file system permission setup by default doesn’t allow the user to install global things.

This is what we do in a circle CI script - replace the circleci user id with yours:

sudo chown -R circleci /usr/local/ && chmod -R u+x+w /usr/local/

@tania-m Let me know if the above command doesn't fix the issue and we can reopen.

It seems the culprit is at least ngrok which installs something extra: inconshreveable/ngrok#429

The permission change workaround is mentioned there as well, or the (crayz) command

sudo npm i -g wskdebug --unsafe-perm=true --allow-root
