这个烂方法不能用
sudo chmod 777 /Library/Ruby/Gems
sudo chmod go-w /usr/local/bin
来安装一个homebrew
https://docs.brew.sh/Homebrew-on-Linux
sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
继续按照官方说的做，基本上都是环境的问题。
test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv) test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv) test -r ~/.bash_profile && echo "eval $($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile echo "eval $($(brew --prefix)/bin/brew shellenv)" >>~/.profile
安装完毕测试一下
brew install hello
安装了完整版居然好了。。。。好吧
sudo apt-get install ruby-full
如果没好，那就继续
brew install ruby
不知道homebrew的不要问我，因为我也不知道是什么鬼。应该和忍者影分身一种鬼东西。
安装完毕看一下版本号
继续安装sass(我叫他洒洒水)
安装成功，查看一下是否安装成功
landv@Desktop201712556489:~/node$ sass -v
bash: sass: 未找到命令
landv@Desktop201712556489:~/node$
悲惨呀，又是环境问题，明明已经安装成功了
换一条路
npm install -g sass
一样的问题，找不到命令
FUCK～～～～
难道只有Deepin是酱紫～～～
好吧曲线救国，直接吧npm下载到的node-sass加入环境变量
综上所述，那就是卸载ruby再进行安装配置，如果还不行那就再卸载一边。
ERROR: While executing gem ... (Errno::EACCES) Permission denied @ rb_sysopen - /Library/Ruby/Gems/2.3.0/gems/fuzzy_match-2.1.0/.gitignore
报这个错误就执行
sudo gem install cocoapods-core
然后再安装sass
记住千万不要用deepin自带的ruby
重要的事情不怕多说
sudo apt-get install ruby-full
Linux用流了，要比Windows配置快。
Deepin Linux 绝逼是环境的问题，虽然它不背锅吧。
