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：
Defaultin g 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 req ui re TLS/SSL, however the ssl module in Python is not av ailable.

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：

p art1：

首先进入 ‪E:anacondaLibsite–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

右击此电脑>高级系统设置>高级>环境变量>添加环境变量

———————————————————————————————————————————

修改了文件夹的读写权限之后，报错内容为

p art2：WARNING: pip is configured with locations that requi re TLS/SSL, however the ssl module in Python is not av ailable.

PS C:Usersfanch> pip install you-get

即缺少了SSL模块，进入 Win32/Win64 O penSSL Installer for Windows – Shining Light Productionshttps://slp roweb.com/products/Win32OpenSSL.html

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

PS C:Users> pip install you-get
Requirement already satisfied: you-get in e:anacondalibsite-packages (0.4.1620)
PS C:Users> you-get

+ ~~~~~~~

然后重新运行 pip install you-get 命令就可以正常使用了
