python3安装xadmin出现 UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 3444

在学习 Django 时，需要安装 xadmin ，结果出现了一下错误

C:\WINDOWS\system32>pip install xadmin
Collecting xadmin
  Using cached xadmin-0.6.1.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "C:\Users\pinsily\AppData\Local\Temp\pip-build-xzvebsss\xadmin\setup.py", line 11, in <module>
        long_description=open('README.rst').read(),
    UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 3444: illegal multibyte sequence

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\pinsily\AppData\Local\Temp\pip-build-xzvebsss\xadmin\

网上搜索了一下，说是 python3 不支持 xadmin，结果还是找到了解决的方法

从错误中可以看到，是文件README.rst 出现了 Unicode 解码错误，这个文件时没有什么用处的，可以新建一个同名的空白文件替换掉

下载 zip 安装包

新建空白文件README.rst 压缩进 zip 中替换掉同名文件

使用管理员命令行界面进行安装
