【问题描述】：
通过 pip 安装 pandas 后，我尝试按照 these instructions 运行 pd.test()，我收到的错误似乎表明缺少模块。安装了 pytest 和 moto 来解决前两个问题，看起来 google-compute-engine 将是它正在寻找的下一个模块。是否有运行pd.test() 的必要模块列表？
也许有更好的方法来解决这个问题。通常我只会安装一个 anaconda 环境，但这是服务器上现有的 python 环境。
谢谢。

【问题讨论】：
-
您应该向我们展示您遇到的错误。
-
是的，我也在 Ubuntu 17.10 FWIW 上得到了这个，即使测试没有运行，它也能正常工作
-
已更新错误和当前安装的软件包。 @maxymoo pandas 也适用于我，至少对于我现在使用它的用途。如果可能的话，希望测试能够运行。
