python - 安装 Mayavi : UnicodeEncodeError: 'charmap' codec can't encode character

Question

我正在尝试使用 Anaconda 3.6 在 Windows 计算机上安装 Mayavi。

不幸的是，我收到一个我不明白的错误。我仍在探索 Python。

我已经在互联网上查看过其他类似的问题，但找不到任何有效的方法。

你能帮我一下吗？

我也遇到了同样的问题。我的解决方案是从 https://www.lfd.uci.edu/~gohlke/pythonlibs/ 下载“mayavi-4.5.0+vtk81-cp36-cp36m-win_amd64.whl”直接 pip install mayavi-4.5.0+vtk81-cp36-cp36m-win_amd64.whl。
