我正在遵循“学习使用Ruby进行游戏编程”教程，并且难以设置工作空间。我在Windows计算机上使用AWS的cloud9 IDE。我已按照linux安装说明进行操作...
安装Linuxbrew
$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
然后我将以下内容复制并粘贴到命令行中（一次粘贴一次）
$ test -d ~/.linuxbrew && PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"
$ test -d /home/linuxbrew/.linuxbrew && PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:$PATH"
$ test -r ~/.bash_profile && echo "export PATH='$(brew --prefix)/bin:$(brew --prefix)/sbin'":'"$PATH"' >>~/.bash_profile
$ echo "export PATH='$(brew --prefix)/bin:$(brew --prefix)/sbin'":'"$PATH"' >>~/.profile
然后使用
检查它是否正确安装$ brew doctor
我安装了必需的库
$ brew install sdl2 libogg libvorbis
然后尝试安装Gosu gem
$ gem install gosu
但出现以下错误

Building native extensions. This could take a while...

我已确保我使用的是Homebrew / linuxbrew而非rvm的ruby安装版本
$ brew unlink ruby && brew link ruby
我也尝试过
$ gem install gosu --platform=ruby
该错误提及“请参见以下站点的列表： 我尝试遵循的https://github.com/gosu/gosu/wiki/Getting-Started-on-Linux'在尝试安装这些库时出现以下错误。
$ sudo apt-get install build-essential libsdl2-dev libsdl2-ttf-dev libpango1.0-dev \ libgl1-mesa-dev libopenal-dev libsndfile-dev libmpg123-dev \ libgmp-dev

我相信sdl2，libogg和libvorbis已取代了上述库
我不知道如何将Gosu gem放入cloud9
