Ruby中缺少Gem错误

我在Ubuntu 13.04上运行一个木偶安装的Sensu客户端，它反过来执行check procs.rb。。它失败于：

Ubuntu测试 它在那里，但不在宝石清单上。还请注意，“semver”包含在错误的“中间”列表中

如果有必要的话，Sensu还有一个“嵌入式Ruby”，其中也包含一系列宝石。在这方面，两台服务器似乎几乎完全相同

[root@either-vm]# ls -l /opt/sensu/embedded/lib/ruby/gems/2.0.0/gems/

..... lots more .....

任何帮助都将不胜感激！谢谢。

sensu是使用默认的ruby运行还是使用sensu的嵌入式ruby？ 我的默认chef安装使用/opt/sensu/embedded/bin/ruby来运行，因此我的所有检查命令都是/opt/sensu/embedded/bin/ruby check_procs.rb等

我认为这是更好的，因为它保持你的系统ruby如果安装干净，保持sensu只在sensu的嵌入式ruby

您是否使用rvm/rbenv？请显示ruby-v命令的输出，哪个gem，哪个ruby，哪个bundle，如果安装了bundler gem，还显示bundle json
