Python Version=2.6.6

好的，所以这个让我难过。

首先，这是我尝试安装时的回溯。在这种情况下，我跑了：pip install requests 作为根。注意：我知道这是pip版本7.0.3。最新版本的pip会出现相同的回溯。

AttributeError: '_socketobject' object has no attribute 'set_tlsext_host_name'

然后我使用pip uninstall pip卸载了pip并确认删除了egg和二进制文件。然后我使用easy_install pip重新安装它但没有运气。我也尝试了这个，但使用了最新版本的pip和版本7.0.3。同样的事情。

此外，安装get-pip.py会产生这种回溯，这与奇怪的相似：

让我感到困惑的是追溯的最后4行。在分析了追溯之后，我潜入了蛋。

显然，从回溯中，错误来自ssl_wrap_socket函数，该函数在connection.py中调用。追溯说ssl_wrap_socket调用{urlib3_path}/contrib/pyopenssl.py在45-50中定义，但是，在查看connection.py的行# connection.py from .util.ssl_ import ( resolve_cert_reqs, resolve_ssl_version, ssl_wrap_socket, assert_fingerprint, ) 时：

ssl_wrap_socket

{urllib3_path}/util/ssl_.py应该从不包含有问题的代码行的pyopenssl导入，但是根据不是正在发生的回溯。

我不知道发生了什么但是假设这是一些我不知道的关于python的巧妙。如果有人有任何线索请告诉我。

编辑：新发展！

当从github绊倒this bit of the requests code时，似乎请求库实际上将pyopenssl注入到urllib3库中，该库解释了回溯。但是我仍然不确定如何解决这个问题。

Edit2：解决方案！

原来urllib3库被注入了错误的pyopenssl！在我发现请求将urllib3注入pyopenssl.py库后，我检出了def inject_into_urllib3(): 'Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.' connection.ssl_wrap_socket = ssl_wrap_socket util.HAS_SNI = HAS_SNI 并找到了此功能：

ssl_wrap_socket

pyopenssl.py在OpenSSL.SSL中定义，并依赖于pyOpenSSL-0.15.1-py2.6.egg。

我跳到site-packages文件夹中的0.15.1，只是为了确保检查版本>>> import OpenSSL.SSL as ssl >>> ssl.__file__ 。经过一番思考后，我打开了解释器并运行了

lib64/python2.6/site-packages

其中告诉我，我在OpenSSL中有一个OpenSSL目录被引用而不是pyOpenSSL鸡蛋中的0.10目录，它只是版本instance_double！这当然是什么导致原始错误被抛出。删除该目录后，Pip似乎没有问题。

答案 0 :(得分：0)

我尝试使用devunt的easy_install代码行，但它没有用。它拒绝访问一堆冲突的python 2.7文件。我基本上和pip有同样的问题。我在Mac OSX上遇到了点数7.0.3并且得到像scikit，numpy和scipy这样的东西，我需要升级到7.1.0。我在Python 2.7.6上，在我尝试下载mysql-python后跟踪错误消息后，我收到了一条错误消息，如图所示，并跟随它来源，这是一个错误消息，因为一个不稳定的系统https＆＃39;的SSL安全性（即Python 2.7.6）。我的错误信息是：

You are using pip version 7.0.3, however version 7.1.0 is available.

因此，据我所知，这个错误是由与Python 2.7.6上Mac OS X捆绑在一起的不兼容性驱动的。因为Mac上的brew是我过去用来升级python的东西，所以我使用＆＃34; brew update＆＃34;当brew更新时，我去了＆＃34; brew install升级python --upgrade python＆＃34;完成后我检查了我的版本，如下所示：

John-Mulhalls-MacBook-Pro:Python_DataBase_Project jmulhall$ brew --version
0.9.5
John-Mulhalls-MacBook-Pro:Python_DataBase_Project jmulhall$ python --version
Python 2.7.10
John-Mulhalls-MacBook-Pro:Python_DataBase_Project jmulhall$ pip --version
pip 7.1.0 from /usr/local/lib/python2.7/site-packages (python 2.7)
John-Mulhalls-MacBook-Pro:Python_DataBase_Project jmulhall$

我解决此错误的经验教训是将python升级到2.7.9（我读过有关Pip的先前版本中的错误）或更高版本。 Pip将捆绑Python 2.7.10作为Pip 7.1.0。我成功安装了＆＃39; brew install mysql-python＆＃39; 当回到数据科学，决策树和python时，将会安装颠簸，scipy和scikit。希望这有助于兄弟们...... ..
