Jekyll安装

安装ruby

Mac自带的ruby，默认为2.6.0，无法满足要求，需要安装3.0以上版本

   brew install ruby

注：版本号可通过 ruby -v查看，若命令无法识别，查看是否在环境变量中配置

安装Jekyll

gem install jekyll bundler

注：验证gem是否安装正确，可以查看对应目录

❯ ls  ~/.gem/ruby/
2.6.0 3.0.0
❯ ls ~/.gem/ruby/3.0.0/bin
bundle  bundler jekyll
  

设置环境变量

echo `export PATH=$PATH:$HOME/.gem/ruby/3.0.0/bin` ~/.bash_profile
source ~/.bash_profile
  

注：无.bash_profile自行创建，或者创建软链到该目录，或者直接切到该目录执行(如果不嫌麻烦)。

验证

❯ jekyll -v
jekyll 4.3.1
  

可能遇到的问题

gem安装扩展失败

cannot load such file – webrick

注：ruby配置脚本说明

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH run:
  echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile

For compilers to find ruby you may need to set: 编译中使用
  export LDFLAGS="-L/usr/local/opt/ruby/lib"
  export CPPFLAGS="-I/usr/local/opt/ruby/include"

For pkg-config to find ruby you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"
