    安装 Ruby

    我看本机 yum install ruby 默认安装的是 2.5 版本。
    但是我想安装 3.0 版本的 ruby。

    > dnf module reset ruby -y
    > yum install @ruby:3.0
    > ruby --version
    ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-linux]

    换国内源镜像

    执行 bundle install 时,会发现卡住不动了,猜测大概率是国内直连 rubygems 源网络不行。
    所以尝试更换国内源:

    bundle config mirror.https://rubygems.org https://gems.ruby-china.com
    

    果然速度快多了。

    如果是 gem install 卡住,配置:

    gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
    

    参考:https://gems.ruby-china.com/

    安装 ruby-dev or ruby-devel 依赖

    虽然 bundle install 可以顺畅的执行了,但是报错:

    An error occurred while installing strscan (3.0.5), and Bundler cannot continue. Make sure that gem install strscan -v ‘3.0.5’ –source ‘https://rubygems.org/’ succeeds before bundling.

    手动执行:

    gem install strscan -v '3.0.5'
    

    报错:

    Fetching strscan-3.0.5.gem
    Building native extensions. This could take a while...
    ERROR:  Error installing strscan:
    ERROR: Failed to build gem native extension.

    You might have to install separate package for the ruby development
    environment, ruby-dev or ruby-devel for example.
    extconf failed, exit code 1
    Gem files will remain installed in /usr/local/share/gems/gems/strscan-3.0.5 for inspection.
    Results logged to /usr/local/lib64/gems/ruby/strscan-3.0.5/gem_make.out
    

    看起来是需要安装 ruby-dev 或 ruby-devel。执行:

    yum install ruby-devel
    

    确认确实安装的是 ruby-devel 3.0.

    再次执行 bundle install 就可以正常安装依赖了。
