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

Rbenv global 2.6.3帮助我解决了这个问题。

其他回答

运行这个

$ rbenv init
# Load rbenv automatically by appending
# the following to ~/.zshrc:

eval "$(rbenv init -)"

按照说明,(在我的例子中,添加到~/.zshrc);)


同样重要的是:更改只有在重新启动控制台时才生效。两个选项

输入source <modified file> 关上再打开

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.

这在Mac上很管用

sudo chown -R $(whoami) $(brew -prefix)/*

我使用下面的命令删除了这些目录

sudo rm -rf \
  /Library/Ruby/Gems/2.6.0/{build_info,cache,doc,extensions,gems} \
  /Library/Ruby/Gems/2.6.0/specifications/*.gemspec \
  /Library/Ruby/Site

然后安装可可豆荚使用sudo宝石安装cocoapods 这对我很有效。谢谢

请小心使用sudo !!!!!!只有当你知道你在做什么!!!!!!!!!!!!

在安装macOS Catalina后,我也遇到了同样的问题。我尝试下命令和它的工作。

sudo gem update
