这次准备用pip安装一下you-get这个包，出现上面报错：
报错内容一：
Defaulting to user installation because normal site-packages is not writeable
这里提示我们包无法正常读入，没有书写权限
报错内容二：
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
这里提示我们缺少openssl模块
下面我们分别来解决这两个问题：
part1：
首先进入 E:\anaconda\Lib\site-packages 这个指定位置，修改用户的读写权限
-----------------------------（在这之前，还应当把这几条路径加入环境变量）----------------------------------
已添加则忽略该部分

修改了文件夹的读写权限之后，报错内容为
part2：WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

选择 Win64 OpenSSL v1.1.1q Light 的 MSI进行下载点击安装即可
这之后 you-get命令还是不能使用，一方面你需要返回第一步，改写相关的几个文件夹Lib和script的读写权限，另一方面需要删除 e:\anaconda\lib\site-packages下原有的安装文件

然后重新运行pip install you-get 命令就可以正常使用了
