我正在安装一台新的Windows 10 PC。在尝试为Python 3.7.3安装vtk 8.1.2时遇到了问题，这是PC上唯一的版本。
这就是我尝试使用pip 19.1.1和wget的方法：
C:\Users\staff>pip install vtk
Collecting vtk
ERROR: Could not find a version that satisfies the requirement vtk (from
versions: none)
ERROR: No matching distribution found for vtk
C:\Users\staff>wget https://files.pythonhosted.org/packages/6b/55/.../vtk-8.1.2-cp37-cp37m-win_amd64.whl

出于格式化目的，我省略了完整的wget link。 为了避免混乱，我宁愿让PC没有虚拟环境和多个Python版本。你有什么建议吗？
