Question

我一直在尝试更新cocoapod。在这之间，我更新了Ruby和RVM。现在，当我在新的ios项目中尝试pod init时，显示以下内容

Traceback (most recent call last):  
2: from /usr/local/bin/pod:23:in `<main>'
1: from /usr/local/Cellar/ruby/2.5.1/lib/ruby/2.5.0/rubygems.rb:308:in `activate_bin_path'
/usr/local/Cellar/ruby/2.5.1/lib/ruby/2.5.0/rubygems.rb:289:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) with executable pod (Gem::GemNotFoundException)

我检查了以下内容，

ruby --version

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin16]

rvm list rubies

=* ruby-2.5.1 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

Answer 1

请使用以下命令将cocoapods安装到/usr/local/bin中，而不要安装到/usr/bin中：

sudo gem install -n /usr/local/bin cocoapods

您应该先删除cocoapods，然后再重新安装：sudo gem uninstall cocoapods

Answer 2

您可能会通过将cocoapods gem安装到当前RVM安装的Ruby中来解决此问题：

由于您正在使用RVM，因此无需使用gem install cocoapods来安装或更改有关Ruby的任何命令。使用sudo安装gems时，是将其安装到系统的Ruby安装中，而不是RVM Ruby中。这可能会导致RVM环境与系统Ruby之间的交互出现问题。

Answer 3

我遇到了同样的错误。但是卸载和sudo gem install -n /usr/local/bin cocoapods对我不起作用。

所以我尝试了rvm list rubies并发现警告：

Warning! PATH is not properly set up, '/Users/xxx/.rvm/gems/ruby-2.1.3/bin' is not at first place,
         usually this is caused by shell initialization files - check them for 'PATH=...' entries,
         it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
         to fix temporarily in this shell session run: 'rvm use ruby-2.1.3'.

我不知道发生了什么，所以我关注了这个问题：Warning! PATH is not properly set up, usually this is caused by shell initialization files

我做了rvm reset和rvm version。警告消失了。

然后我运行sudo gem install -n /usr/local/bin cocoapods

这解决了我的问题。如果有人遇到类似情况，请将其张贴在这里。

Answer 4

尝试

$ sudo gem install cocoapods

Answer 5

如果您已经安装了 cocoapods 并且您最近删除或移动了当前文件夹，请再次尝试重新输入路径。也许终端不知道你在哪里了。这解决了我的问题。

Answer 6

请使用以下命令将 cocoapods 安装到 /usr/local/bin 而不是 /usr/bin 中：

sudo gem uninstall cocoapods
sudo gem install -n /usr/local/bin cocoapods

无法在iOS Project中安装Pods
