总所周知 ujson 要比 json 模块高效,可是安装也太麻烦了。之前在 Windows7 中使用 Python2.x 的第三方模块 ujson ,使用pip install ujson 安装时没有问题的,换成 Windows10 的时候报错了。

报错如下:

C:\>pip install ujson

大体意思就是缺少编译ujson的C++编译工具,经过查阅得知:

Python 2.7需要Microsoft Visual C++ 9.0的库
Python 3.6需要Microsoft Visual C++ 14.0的库

很显然,解决方案只有两种了:

  • 下载whl文件直接安装(Python2和Python3适用)
    下载地址:https://www.lfd.uci.edu/~gohlke/pythonlibs/
    在这里可以搜索你想要的库!!!
    使用 pip install xxx.whl 安装即可。
  • 下载Microsoft Visual C++ Build Tools(Python3适用)
    下载微软的C++编译工具,CSDN上下载竟然花钱,气死我了...我特么还是学生呢...在这里下载吧,免费的:http://down.51cto.com/data/2452424
    下载完成使用管理员权限打开,安装Windows10SDK和.NET框架即可!!!
