我无法使pip install scrypt正常工作，经过一轮阅读之后，我尝试安装Visual Studio 2017，但没有成功，然后我尝试遵循Windows Compilers的示例
MinGW-w64是另一种C / C ++编译器，可与所有3.4以下的Python版本一起使用。
Install Win-builds into C:\MinGW_w64.
Open Win-builds, switch to install at least binutils, gcc, gcc-g++, getext, mingw-w64, win-iconv, winpthreads, zlib, and click Process.
Add C:\MinGW_w64\bin to the PATH environment variable.
Create a distutils.cfg file with the following contents in the folder \Lib\distutils in Python install directory :
[build] compiler=mingw32
[build_ext] compiler=mingw32
产生了这个新错误，

它默认为REEE的其他错误消息！ “仅将此标题与Microsoft Visual C ++编译器一起使用！”当我“重新安装” disutils.cfg时。 令我震惊的是，我已经将所有这些库安装在已使用大约6年的系统上，并且炸毁了，而我只需要构建新的库即可。我知道它可以安装，我只是不记得我是如何将其拔出的。
答案 0 :(得分：0)
我建议尝试python -m easy_install scrypt。过去，每当出现错误failed with error code 1时，我都会使用easy_install而不是pip，它可以正常工作。
答案 1 :(得分：0)
pip install scrypt==0.8.11 :)
在.11上方还会显示出类似这样的错误。
安装Win64OpenSSL-1_1_1c.msi..
当我为ida 7安装keypatch时收到了类似的错误
