问题

为了在mac中使用tmuxinator，按照网上的教程使用rvm升级了系统的ruby版本，ruby升级完成后却发现执行colorls相关命令时，报了如下错误：

解决办法

在终端执行以下命令：

xcode-select --install
brew install rbenv
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc
echo 'export LDFLAGS="-L/usr/local/opt/openssl/lib"' >> ~/.zshrc
echo 'export CPPFLAGS="-I/usr/local/opt/openssl/include"' >> ~/.zshrc
echo 'export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"' >> ~/.zshrc
sudo gem pristine --all #that produced a permissions error, but i don't care everything worked
sudo gem install colorls

如果执行xcode-select --install时提示

1
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

可以忽略。
