运行时出现错误:
vagrant@vagrantup:~$ sudo gem list
ERROR: Loading command: list (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::ListCommand
即使我不使用 sudo，我也会收到相同的错误消息。
它在 Ubuntu 10.4 上，我已经安装了 zlib 库:
vagrant@vagrantup:~$ sudo aptitude search zlib

我正在使用http://www.vagrantup.com我安装了rvm后出现错误。
问题可能是什么？
最佳答案
Ruby 是如何安装的？如果安装 Ruby 时没有 zlib 支持，那就会出现问题。
你可以阅读我的文章here在 Ubuntu 上安装 RVM。在编译 Ruby 之前，您必须安装 zlib 和 zlib-dev 软件包(以及 Ubuntu 中的一些其他软件包)。您可能只需要安装这些并重新编译 Ruby。
关于ruby - 无法运行 "gem list"!，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3578592/
