cppjieba_rb のインストール失敗により、開発環境のセットアップができない

[nsuchy (Nathaniel Suchy)]

Hi,

I am attempting to setup a development enviroment for Discourse.

When running bundle install based on the instructions at Beginners Guide to Install Discourse on macOS for Development I get an error.

An error occurred while installing cppjieba_rb (0.3.0), and Bundler
cannot continue.
Make sure that `gem install cppjieba_rb -v '0.3.0' --source
'https://rubygems.org/'` succeeds before bundling.

I follow the suggestion and get the following output

$ gem install cppjieba_rb -v '0.3.0' --source
ERROR:  While executing gem ... (OptionParser::MissingArgument)
    missing argument: --source

What am I doing wrong and how can I fix the issue?

[sam (Sam Saffron)]

Can you try the docker based dev env, it is way simpler

[nsuchy (Nathaniel Suchy)]

I just checked my system and realized some dependencies and the ruby version manager thing needed to be configured . That might be while bundler is installing.

That said Docker does sound simpler, I intend to submit pull requests to Discourse, is the Docker environment still right for me? If so could you link me to information on it? Thanks

[sam (Sam Saffron)]

Yes it is perfect for that, search for docker development environment, there is a howto

[nsuchy (Nathaniel Suchy)]

The only thing I could find was Setting up Docker in Virtualbox for 'production' testing which looks terribly outdated considering it’s use of Ubuntu 13. Could you link me to exactly the thread you’re talking about?

[featheredtoast (Jeff Wong)]

Sam’s talking about this one: Beginners Guide to Install Discourse for Development using Docker

[nsuchy (Nathaniel Suchy)]

Thanks, and turns out - since I tried to install while on system Ruby rather than the correct version, future bundle installs were trying to use system rather than correct bundler. Deleting discourse and recloning solved the issue.

[nsuchy (Nathaniel Suchy)]

And I can now start making changes and creating new bugs

[Kids_Unleashed]

Im getting the same error. I am running ubuntu on vagrant. Any know how to get passed this? @sam

[Falco]

Vagrant is not a supported dev environment, please follow one of the supported Developer Environment guides:

• Docker (Ubuntu & macOS)
• Ubuntu (Linux)
• macOS
• Windows 10

同じ問題が発生しています。このソフトウェアをテストするためのローカル Discourse 環境を構築するのがこんなに難しいなんて、少し悲しいですね。

[Stephen]

どの問題ですか？もう少し具体的に教えていただけますか？

$ gem install cppjieba_rb -v ‘0.3.0’ --source ERROR: While executing gem …

I can’t seem to get the environment to set up correctly due to this cppjieba_rb library

Tried to fix by: sudo gem install cppjieba_rb -v '0.3.3' --source 'https://rubygems.org/'

Here was it’s output:

make: *** [internal.o] Error 1

Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/cppjieba_rb-0.3.3 for inspection.
Results logged to /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/cppjieba_rb-0.3.3/gem_make.out

An error occurred while installing cppjieba_rb (0.3.3), and Bundler cannot continue.
Make sure that `gem install cppjieba_rb -v '0.3.3' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  cppjieba_rb

FYI: Xcode version info:

The Google God has yielded no solutions or fruit. There was tangential GitHub issue which suggested:

Try running gem install rake and then running bundler again. If that doesn’t work, there are a few other solutions listed in the above post.

.. however, this yielded nor any fruit and the error remains even if I start the cloning process from scratch again.

更新:

この問題は、関連する TLDR: Mac に標準搭載されている Ruby を使用しないでください によって解決されたようです。

参照: xavi- 氏が 2019 年 5 月 16 日 にコメント

彼の（xavi の）指示に従い、rbenv に切り替えて bundle install が実行できましたが、まだ確認が必要です……

更新 2:

確認済み: rbenv に切り替え、現在の PATH 環境変数 ~/.rbenv/shims を設定することで、この問題は解決しました。

export PATH=~/.rbenv/shims:$PATH

[deepu256 (Sandeep Kalidindi)]

@neounix

export PATH=~/.rbenv/shims:$PATH

このエラーで詰まっていたのですが、あなたが提案されたこと（PATH に rbenv を設定すること）が私の場合にも機能しました。

本当にありがとうございます。
