Python pip安装赢得'；不要安装在我的机器上

因此，我正在尝试将Django版本升级到1.4.2，但当我执行

pip install Django==1.4.2-vvv时，我得到：

有什么想法吗？
我可以通过这样做来解决它：

pip安装——冗长https://pypi.python.org/packages/source/D/Django/Django-1.4.2.tar.gz#md5=6ffecdc01ad360e1abdca1015ae0893a

问题是，首先我仍然不知道问题的原因
django 1.4.2在pyPi上可用吗？是的：什么是
/tmp/pip vRFtxt build
。你能看一下吗？为什么你要升级到两年前的版本，而不是最新的（1.6）？是的@DanielRoseman我需要1.4版这可能意味着搜索出错，而不是实际的d/l安装。正如我所说的，如果您可以查看创建的tmp文件的内容，它可能会告诉您下载了什么而不是实际的存档。
