git cloneした後のbandle installできない奮闘記

git cloneしたファイルをbundle！おりゃ！

$ bundle install --path vendor/bundle

つらつら〜と表示された後

An error occurred while installing ffi (1.10.0), and
Bundler cannot continue.
Make sure that `gem install ffi -v '1.10.0' --source
'https://rubygems.org/'` succeeds before bundling.

まぁ何か起こる予感はしてたので、、

書かれてる通りコマンドしてみる
$ gem install ffi -v '1.10.0' --source'https://rubygems.org/'

ERROR:  While executing gem ... (OptionParser::MissingArgument)
    missing argument: --source
zsh: no such file or directory: https://rubygems.org/

そんなもんねぇよと怒られてるっぽい。。

ってことで先人様の知恵を拝借

Post-install message from rubyzip:
RubyZip 3.0 is coming!
**********************

The public API of some Rubyzip classes has been modernized to use named
parameters for optional arguments. Please check your usage of the
following classes:
  * `Zip::File`
  * `Zip::Entry`
  * `Zip::InputStream`
  * `Zip::OutputStream`

Please ensure that your Gemfiles and .gemspecs are suitably restrictive
to avoid an unexpected breakage when 3.0 is released (e.g. ~> 2.3.0).
See https://github.com/rubyzip/rubyzip for details. The Changelog also
lists other enhancements and bugfixes that have been implemented since
version 2.3.0.
Post-install message from sass:

Ruby Sass has reached end-of-life and should no longer be used.

* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
  primary implementation: https://sass-lang.com/install

* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
  sassc gem: https://github.com/sass/sassc-ruby#readme

* For more details, please refer to the Sass blog:
  https://sass-lang.com/blog/posts/7828841

Zipがどうこう出てるけど一旦起動するか確かめる。
