ruby – 如何在Mac OS X上安装没有sudo的gem_语言综合

概述我读了很多帖子,但到目前为止还没有人做过这个伎俩. 我怎么能在OSX(El Capitan Beta)上为我自己的用户安装一个gem？帖子建议例如指定-user-install但我不能在没有sudo的情况下调用gem,因为它会抛出权限错误. 我跟着“Install gem as user on OSX 10.10 Yosemite”但仍然不能打电话给宝石. 我按照上面的指南安装了Homebrew, 我读了很多帖子,但到目前为止还没有人做过这个伎俩.

我怎么能在OSX(El CAPItan Beta)上为我自己的用户安装一个gem？帖子建议例如指定-user-install但我不能在没有sudo的情况下调用gem,因为它会抛出权限错误.

我跟着“Install gem as user on OSX 10.10 Yosemite”但仍然不能打电话给宝石.

我按照上面的指南安装了Homebrew,安装了rbenv,安装了一个带rbenv的Ruby版本,检查它是否正确加载,但指南的最后一步是调用gem install,我仍然无法做到.

安装rbenv后调用gem会导致：

/Users/Me/.rbenv/versions/2.1.5/lib/ruby/2.1.0/rubygems/stub_specification.rb:71:in `initialize': Permission denIEd @ rb_sysopen - /Users/Ne/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/speci

rbenv env转储：

RBENV_VERSION=2.1.5RBENV_ROOT=/Users/Me/.rbenvRBENV_HOOK_PATH=:/Users/Me/.rbenv/rbenv.d:  /usr/local/etc/rbenv.d:  /etc/rbenv.d:  /usr/lib/rbenv/hooksPATH=/Users/Me/.rbenv/versions/2.1.5/bin:  /usr/local/Cellar/rbenv/0.4.0/libexec:  /Users/Me/.rbenv/plugins/rbenv-env/bin:  /Users/Me/.rbenv/shims:  /usr/local/heroku/bin:  /usr/local/sbin:  /usr/local/bin:  /usr/local/share/npm/bin:  /Applications/Atom.app/Contents/Resources/app/apm/bin:  /Users/Me/.bin:  /Applications/Atom.app/Contents/Resources/app/apm/node_modules/atom-package-manager/bin:  /usr/local/bin:/usr/bin:  /bin:  /usr/sbin:/sbin:  /opt/X11/bin:  /usr/local/MacGPG2/binRBENV_DIR=/Users/Me/.rbenv/plugins

“@L_419_1@”似乎有关,虽然除了使用我可能要做的其他方法之外没有解决.

解决方法如果你不能使用没有sudo的gem,听起来你没有正确初始化rbenv因为垫片不可用.

这些步骤来自the documentation.确认您已完成所有 *** 作：

Add ~/.rbenv/bin to your $PATH for access to the rbenv command-line utility.

$echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile

Ubuntu Desktop note: Modify your ~/.bashrc instead of ~/.bash_profile.

Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.

Add rbenv init to your shell to enable shims and autocompletion.

$echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

Same as in prevIoUs step,use ~/.bashrc on Ubuntu,or ~/.zshrc for Zsh.

Restart your shell so that PATH changes take effect. (opening a new terminal tab will usually do it.) Now check if rbenv was set up:
