我一直试图在Windows 10机器上安装apache-airflow，但我做不到。最初，我收到“缺少Microsoft Visual C ++ 14.0”错误，然后通过Visual Studio安装程序安装了它。现在我遇到了一些新的错误：

我尝试重新安装Visual Studio，仍然没有运气，我不知道该怎么办。您能提出一些解决方案吗？
答案 0 :(得分：1)
对于只是通过谷歌搜索找到此Stack Overflow帖子的人，Apache Airflow当前支持Python 3.7（但最初询问此问题时不支持）。
要解决上述“需要Microsoft Visual C ++ 14.0”错误，您需要安装Windows 10 SDK for Desktop C++ as mentioned here。不要忘记关闭/重新打开终端，或者之后再运行refreshenv命令。
