uninitialized constant Gem::Command (NameError) when building extension

[jamesgecko]

I get a compilation error when installing this CLI gem.

I'm using an M1 MacBook running macOS 12.2.
Ruby 3.1.0p0 (installed via MacPorts).

Try #34

[EeveeEuphoria]

Getting the exact same issue here on Manjaro Linux, latest version of ruby. I'm not familiar with ruby so I don't know how to utilize #34.

Same on Windows 10 with "gem install neocities" and "gem install --no-document neocities". Full Ruby devkit install (tried it with 64 and 32 versions) with "gem update --system" "gem install rake". Also tried the older version of neocities down to 0.0.11

#34 does fix the problem for me. Here's a terminal session showing how to install it. I'm using GitHub CLI on macOS.

For anyone else having this issue, I spent hours trying to get the neocities CLI to work using Ruby 3.1 and kept getting this same error no matter what I tried, using #34 , using the instructions given by Jamesgecko, everything. I finally decided to do a fresh install of Ruby for version 2.7.5 with the devkit, and just simply using "gem install neocities" worked like a charm on the first try.

Use Ruby 2.7.5 without any problem

[kyledrake]

I merged #34 which will hopefully solve this.
