我已经在 Windows 7 上安装了 Python 3.4.1，包括 pip，并且在安装过程中选择了将 python.exe 添加到 PATH。

运行 pip install requests 时我得到:

    C:\Python34>pip install requests
Requirement already satisfied (use --upgrade to upgrade): requests in c:\python3
4\lib\site-packages

During handling of the above exception, another exception occurred:

我想知道这些异常是什么意思？

是否真的像日志中给出的那样成功安装了软件包，它们是否运行良好，或者我做错了什么。

为什么会出现异常以及如何摆脱它们？

最佳答案

所有的权限异常意味着你的命令提示符没有管理员权限。

以管理员身份运行命令提示符(在开始菜单中搜索 cmd，右键单击，以管理员身份运行)。如果这不起作用，请尝试重新安装 pip；文件权限可能以某种方式搞砸了。
