安装请求[security]后Pip断开

Question

运行后pip install requests[security]运行任何pip命令都会输出以下错误。我尝试过删除和重新安装python pip以及python pyopenssl。想知道是否有人有建议或遇到过这个问题？我不能升级python或Debian，我想让pip重新工作。

Debian 6.0.10
Python 2.6.6
python pip 1.5.6

$ pip --version

Answer 1

不幸的是，sudo apt-get autoremove并没有神奇地删除。当然，我也尝试了标准的pip uninstall ndg-httpsclient，但首先运气不佳。

最后，我不得不进入python程序目录并强行将其删除

$ cd usr/local/lib/python2.7/dist-packages
$ sudo rm -rf ndg_httpsclient-0.3.3-py2.7.egg-info
$ sudo rm -rf ndg_httpsclient-0.3.3-py2.7-nspkg.pth
$ sudo rm -rf ndg

Answer 2

只需执行以下操作即可解决此问题： sudo apt-get autoremove

Answer 3

请在此处引用此错误：https://github.com/cedadev/ndg_httpsclient/issues/5

我怀疑问题是Ubuntu上的pip使用的是ndg_httpsclient，而当前的ndg_httpsclient与旧的pyasn1，所以pip在安装过程中会断裂。

无论如何，可以选择的pyasn1的有效版本是：0.0.9a0，0.0.10a0、0.0.11a0、0.0.12a0、0.0.13a0、10.0.13b0、0.0.13、0.1.1、0.1.2、0.1.3、0.1.4、0.1.5、0.1.6、0.1.7、0.1.8、0.1.9

我找到了一个半合理的解决方法。

但是0.0.13没有安装在Python 3上，所以我认为最低应至少为0.1.1。

然而，我看到密码学需要pyasn1>=0.1.8，所以它是很可能大多数人很快就会使用它。
