How to fix Ruby gem not being found?

syssunn · 2019-02-10 15:09:24

I installed Ruby from Arch repositories. After, following Arch Wiki instructions on Ruby, I edited my ~/.profile adding:

PATH="$PATH:$(ruby -e 'print Gem.user_dir')/bin"
export GEM_HOME=$HOME/.gem

Then, following AsciiDoctor guide on installing asciidoctor-pdf, I did run gem install asciidoctor-pdf --pre, and successfully installed it and its dependencies. But when I try to run asciidoctor-pdf, it outputs the following:

Traceback (most recent call last):
	2: from /home/user/.gem/ruby/2.6.0/bin/asciidoctor-pdf:23:in `<main>'
	1: from /usr/lib/ruby/2.6.0/rubygems.rb:302:in `activate_bin_path'
/usr/lib/ruby/2.6.0/rubygems.rb:283:in `find_spec_for_exe': can't find gem asciidoctor-pdf (>= 0.a) with executable asciidoctor-pdf (Gem::GemNotFoundException)

How can I fix that?

My gem env:

Works flawlessly for me, plus there's utterly no need to set GEM_HOME as it is already the default. As of a minute ago, the wiki no longer recommends setting this.

Why is your GEM_PATHS completely screwed up? It doesn't list the system dir at all.

I've removed it from my .profile

I don't really know, maybe because I also had set gem PATH to my .zshrc, but I just removed it from there and source ~/.zshrc && source ~/.profile

Now, my gem env outuputs the following:

  - GEM PATHS:
     - /usr/lib/ruby/gems/2.6.0
     - /home/user/.gem/ruby/2.6.0

Also, now asciidoctor-pdf isn't found and when I try to run asciidoctor I have the following output:

$ asciidoctor
Traceback (most recent call last):
	1: from /usr/bin/asciidoctor:23:in `<main>'
/usr/bin/asciidoctor:23:in `load': cannot load such file -- /home/user/.gem/ruby/2.6.0/gems/asciidoctor-1.5.8/bin/asciidoctor (LoadError)

Though my reply does not answer your question directly, but quarry ruby gem repo contains ruby-asciidoctor-pdf that lets you install the package easily.
