The "path" argument must be of type string. Received type undefined

Hi,

I'm executing following steps to install nvs on Docker image with ubuntu 18.04LTS

export NVS_HOME="$HOME/.nvs"
git clone https://github.com/jasongin/nvs "$NVS_HOME"
. "$NVS_HOME/nvs.sh" install

The last command ends up with an error:

The "path" argument must be of type string. Received type undefined

Should I update any config file to make it work?

Hmm, I haven't seen this before, and I don't know exactly where that error is coming from. Can you set this variable before the install step?

export NVS_DEBUG=1

Then it should print a stack trace with the error, that will hopefully pinpoint the problem.

Ahh, so the problem is a missing SHELL environment variable. Normally that would be set to the path to your preferred shell, e.g. /bin/bash.

The install process tries to detect the user's preferred shell so it can choose to add nvs to either .bashrc or .zshrc or .profile. But probably it should skip that step (and print a warning) if the SHELL environment variable is not set, or is set to some unknown shell.
