0. 背景
- 在使用 pip install 命令安装第三方包的时候，有时会遇到安装失败的问题；
- 在这些问题中，有一种问题很让人头大，那就是安装包本身就有问题；
-- 比如下面的案例中，安装包中的代码就因为编码格式问题，导致安装失败； - 在这中情况下，我们往往就需要手动下载安装包，然后对安装包进行编辑，然后重新打包安装；
1. 环境
- windows 10；
- aiooss-0.1.2.；
2. 问题
- 使用 pip 安装 aiooss 包时出现如下报错：
Collecting aiooss
Using cached aiooss-0.1.2.tar.gz (16 kB)
ERROR: Command errored out with exit status 1:

3. 原因
- 通过分析，我们发现报错的原因是由于 setup.py 文件中的 readme = f.read() 读取文件失败导致的；
- 我们手动下载安装包，地址：https://pypi.org/project/aiooss/0.1.2/#files，解压之后使用文本编辑器打开 setup.py 文件，发现问题了问题是由于 README 文件格式不可读导致的；

4. 解决
- 手动下载第三方文件包，将安装包解压缩（和前面第三步的工作一样，此处不赘述）；
- 修改文件包，将上面图片箭头指向位置的代码，修改成下面的代码；
with open('README.rst', mode='r',encoding='UTF-8') as f:
readme = f.read()
- 找到 python 安装包 site-packages 路径，site-packages 就是 python 安装目录下的 Lib\site-packages；
where python # 查看 python 安装路径
- 下载 7z 压缩工具，下载地址：https://www.7-zip.org/，并安装；
- 使用 7Z 将前面修改好的文件包压缩成 tar 格式，并复制到 site-packages 目录中；
- pip 安装 tar 文件包。问题解决；
