我在使用 python 2.7.9-2 amd64 的 Debian 8 系统上遇到问题:
marius@pydev:/usr/lib/python2.7/dist-packages/urllib3/contrib$ pip search doo

我检查了lib并尝试修补/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/contrib/pyopenssl.py

_openssl_versions = {

有人可以启发我如何解决这个问题吗?如果有人有线索,那就太棒了。我用谷歌搜索了这个问题,只发现不完整的补丁,而且很乱。一旦这个问题得到修复,也可能是错误跟踪器的一个案例。我对所有 Python 包都有这个问题。
