下面是我需要做的。
要运行规范，需要安装RSpec。首先，在项目的根目录下运行gem install bundler。然后，运行bundle install。要运行单个spec文件，可以运行如下命令:要一次运行所有规格，请运行bundle exec rspec。
所以，我在终端中输入gem安装捆绑器，并得到错误:
您没有/Library/Ruby/Gems/2.3.0目录的写权限。
这是在atom的项目文件中
source "https://rubygems.org"
gem "rspec", "~> 3.2.0"
我的问题是:
似乎终端给我的响应，因为我不应该改变ruby上的任何东西，我需要捆绑安装在原子?谁能告诉我如何使用原子或者在原子中运行任何东西?
当前回答
我使用参数——user-install运行以下命令:
gem install name_of_gem --user-install
Edit
There was one gem I still could not install (it required the Ruby.h headers of the Ruby development kit or something), then I tried the different version managers, but somehow that still did not really work as it was stated in the documentations how to just install and switch (it did just not switch the versions). Then I removed all the installed version managers and installed afterwards with brew install ruby the latest version and did set the PATH variable, too. (It will be mentioned after the installation of ruby from brew), which worked.

通常建议使用rbenv或rvm之类的版本管理器。否则，安装的Gems将作为根用户供其他用户使用。
如果你知道你在做什么，你可以使用sudo gem install。

Mac解决方案
安装/更新最新ruby版本的RVM \curl -sSL https://get.rvm.io | bash -s stable 安装打包机 Gem安装捆绑器
这两个命令之后(sudo) gem安装....开始工作
我试了一下，效果很好 导出路径= / opt /组装/ opt / ruby / bin: / opt /组装/ lib / ruby /珠宝/ 3.0.0 / bin:美元的道路 出口LDFLAGS = " - l / opt /组装/ opt / ruby / lib” 出口CPPFLAGS = " - i / opt /组装/ opt / ruby /包括” Gem安装ffi
如果您不是默认的Ruby开发人员，那么所有这些答案对您来说都是陌生的。
将所有这些与nodejs中的nvm关联起来
