$ bundle install

An error occurred while installing http_parser.rb (0.6.0), and Bundler cannot continue.

In Gemfile:
  jekyll was resolved to 4.2.1, which depends on
    em-websocket was resolved to 0.5.2, which depends on
      http_parser.rb

打开错误日志

"pkg-config --exists openssl" 
 package configuration for openssl is not found

原因：没有正确设置PATH导致的问题

mac 使用默认的ruby 版本，要更新最新版本 ruby 并且覆盖

解决方法:

$ brew install ruby

$ brew link --overwrite ruby

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

For compilers to find ruby you may need to set:
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"

在 .zshrc 加入 'export PATH="/usr/local/opt/ruby/bin:$PATH"'

$ source ~/.zshrc
