安装mayavi时安装顺序为PyQt4-->Traits-->VTK-->Mayavi

不要直接在windows的命令窗口下运行直接网络安装的命令，一定要去网站上（ https://www.lfd.uci.edu/~gohlke/pythonlibs/#mayavi ）直接下载相关的whl类文献（版本跟参考中的不太一样，因为网站中没有VTK-8.1.1-cp36-cp36m-win_amd64.whl、mayavi-4.6.1+vtk81-cp36-cp36m-win_amd64.whl的文件）

PyQt4-4.11.4-cp36-cp36m-win_amd64.whl

traits-4.6.0-cp36-cp36m-win_amd64.whl

VTK-8.1.2-cp36-cp36m-win_amd64.whl （VTK 可以通过pip3 install VTK安装，也可以知道需要安装的whl版本）

mayavi-4.6.2+vtk81-cp36-cp36m-win_amd64.whl

即可完美解决。

 

如果找不到VTK-8.1.2-cp36-cp36m-win_amd64.whl，也可以下载VTK-8.2.2-cp36-cp36m-win_amd64.whl，但是对应的mayavi需要下载mayavi-4.6.2+vtk82-cp36-cp36m-win_amd64.whl的版本。
