我想使用pip为python安装jnius库。我在安装过程中遇到错误。这是发生的事情：
C:\Users\Janka\AppData\Local\Programs\Python\Python35-32>python.exe -m pip
install jnius

我无法解决的第一个错误： 可能，我没有setup.py文件。我可以通过pip以某种方式安装吗？或者我该怎么办？也许我有它，如果是的话，我在哪里可以找到它或我如何检查它？

答案 0 :(得分：0)
您需要安装Visual Studio 2015.在安装过程中勾选Languages--> C++.的方框
您还可能需要设置环境变量
GYP_MSVS_VERSION = 2015
或者你可以在这里下载Python 2.7的C ++编译器 https://www.microsoft.com/en-us/download/details.aspx?id=44266
