Python 失败：导入错误（没有名为'；bunch'；的模块）

我尝试使用以下命令运行一些python测试：

nosetests -e --process-timeout=1200 mytests.functional.test_1234

当我这样做时，我会出现以下错误：

======================================================================
ERROR: Failure: ImportError (No module named 'bunch')

接下来，我尝试通过PyCharm安装bunch，这似乎已经成功，但当我运行

pipshowbunch

时，没有返回任何内容

有人知道我做错了什么吗？

我想你可以在pip安装中添加pypi.python.org作为可信主机。尝试：

sudo pip install --trusted-host pypi.python.org bunch

sudo pip install --trusted-host pypi.python.org bunch
