我想用Mayavi.

情况

• 我使用MacBook Air,OSX 10.7.3.
• 我使用Python 2.7.2
• 我virtualenv安装了.但我没有用它来安装.

我手动安装了它的所有依赖项,包括VTK.

因为VTK,我按照其安装指南并安装了python包装器.

现在,如果我打开一个新的终端窗口并打开python,我可以导入vtk而不会出现任何错误.

问题

我尝试使用以下命令安装Mayavi:

pip install mayavi

但是发生以下错误:

它表明[SSL:CERTIFICATE_VERIFY_FAILED].如果requests一个人可以使用verify=False,但在这里做什么.

更新:

在Mac OS X 10.7.5上使用NLTK 3.0的Python 3.6上仍然存在此错误:
