我已经安装了Python 3.5并且在运行时
pip install mysql-python
它给了我以下错误
error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
我在路径中添加了以下行
C:\Program Files\Python 3.5\Scripts\;
C:\Program Files\Python 3.5\;
C:\Windows\System32;
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC;
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC
我的PC上有64位win 7设置.
什么是解决此错误和正确安装模块的解决方案pip.
我刚刚运行了"pip install -U steem"命令,安装工作正常,直到它无法安装pycrypto.之后我做了"pip install cryptography"命令,因为我认为它是缺少的包.所以我的问题是,如何在没有pycrypto-error(或者另外还有pycrypto-package)的情况下安装steem,以及如何卸载我不需要的cryptography-Package.(我使用的是Windows 7和Python 3)
