pip安装requests异常和pip安装beautifulsoup4异常

Question

我在Windows 7上安装了Python 3.4.1，安装时选择了把python.exe添加到PATH里，并且pip也包含在内。

当我运行命令pip install requests时，出现了以下内容：

    C:\Python34>pip install requests
Requirement already satisfied (use --upgrade to upgrade): requests in c:\python3
4\lib\site-packages
Cleaning up...
  Exception:
Traceback (most recent call last):

    os.unlink(fullname)

\\Temp\\pip_build_User\\pip\\pip\\_vendor\\distlib\\w32.exe'

During handling of the above exception, another exception occurred:

C:\Python34>

我想知道这些异常是什么意思？

这些包真的像日志中显示的那样成功安装了吗？它们能正常运行吗，还是我做错了什么？

为什么会出现这些异常，我该如何解决它们？
