Question

我已经把头发拉了大约整整24小时了。我一直在寻找解决方案。我已经尝试了一切我能找到的东西。

我想做什么： 为'knife'程序安装ec2插件;一个非常有用的工具，可以与Chef服务器进行交互。

会发生什么 一切都回来了彩虹和独角兽。 module installed。模块不可用，也无法找到任何成功安装的证据。

我的环境：详细信息在本文末尾。高级别：安装了OSX 10.9.2 w / BREW以及Xcode 5.1

最简单地展示我的问题：

尝试安装gem

bash-3.2$ sudo -E gem install knife-ec2
Fetching: knife-windows-0.5.15.gem (100%)
Successfully installed knife-windows-0.5.15
Fetching: knife-ec2-0.8.0.gem (100%)

Fanstastic！它已经安装好了。整齐。这很简单！ 哦，等等

bash-3.2$ knife ec2
FATAL: Cannot find sub command for: 'ec2'
The ec2 commands were moved to plugins in Chef 0.10
You can install the plugin with `(sudo) gem install knife-ec2

bash-3.2$ sudo knife ec2
FATAL: Cannot find sub command for: 'ec2'
The ec2 commands were moved to plugins in Chef 0.10
You can install the plugin with `(sudo) gem install knife-ec2

它不能以root或普通用户身份使用。

在更多阅读之后（部分见How to install knife-ec2），我尝试了不同的方法

bash-3.2$ sudo ./gem install knife-ec2

Answer 1

我遇到了同样的问题，但使用了不同的插件这让它对我有用：

knife无法找到插件，虽然它说它会寻找gem install“ed”的插件。我认为问题是rvm部分，并且宝石安装在一个完全不同的文件夹中：

~/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1/gems/

您可以使用gem env命令

进行检查

$ gem env
RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.23
  - RUBY VERSION: 1.9.3 (2012-02-16 patchlevel 125) [x86_64-darwin12.5.0]
  - INSTALLATION DIRECTORY: /Users/phil/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1
  - RUBY EXECUTABLE: /Users/phil/.rbenv/versions/1.9.3-p125/bin/ruby
  - EXECUTABLE DIRECTORY: /Users/phil/.rbenv/versions/1.9.3-p125/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-darwin-12
  - GEM PATHS:
     - /Users/phil/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1
     - /Users/phil/.gem/ruby/1.9.1
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - http://rubygems.org/

所以我将宝石链接到我的~/.chef/plugins/knife文件夹，如下所示：

$ ln -s ~/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1/gems/knife-digital_ocean-0.7.0 ./knife-digital_ocean-0.7.0
$ ln -s ~/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1/gems/knife-solo-0.4.2 ./knife-solo-0.4.2

现在knife可以找到插件了：

$ knife digital_ocean
FATAL: Cannot find sub command for: 'digital_ocean'
Available digital_ocean subcommands: (for details, knife SUB-COMMAND --help)

** DIGITAL_OCEAN COMMANDS **
knife digital_ocean droplet create (options)
knife digital_ocean droplet destroy (options)
knife digital_ocean droplet list (options)
knife digital_ocean image list (options)
knife digital_ocean region list (options)
knife digital_ocean size list (options)
knife digital_ocean sshkey list

也适用于ec2插件...

Answer 2

我安装了最新的厨师，然后运行了这个：

% sudo /opt/chefdk/embedded/bin/gem install knife-ec2



% knife ec2 server list                              
WARNING: No knife configuration file found
ERROR: You did not provide a valid 'AWS Access Key Id' value.
ERROR: You did not provide a valid 'AWS Secret Access Key' value.

这是预期的行为。设置正确的AWS凭证后，工作正常

Answer 3

如果你有宝石作为sudo或明确地从/opt/chef/embedded/bin/运行它，你只是依赖于你路径中的knife。

您需要确保gem命令和knife命令来自您认为来自的相同位置。

Answer 4

（跟进通过的人）

在安装gem之前，您可能只需要libxml标头：

$ yum -y install libxml2-devel # or apt-get install libxml2-dev
$ which knife
/usr/bin/knife
$ ls -l /usr/bin/knife
0 lrwxrwxrwx 1 root root 21 Jun  6 06:39 /usr/bin/knife -> /opt/chefdk/bin/knife
$ head -1 /opt/chefdk/bin/knife 
#!/opt/chefdk/embedded/bin/ruby
$ sudo /opt/chefdk/embedded/bin/gem install knife-ec2 --no-rdoc --no-ri

Answer 5

解决方案是使用虚拟盒并安装一个简单的ubuntu映像。
