ImportError:无法使用PIP导入名称HTTPSHandler

Question

使用pip安装python包时遇到HTTPSHandler错误,以下是堆栈跟踪,

我以前编辑Modules/setup.dist文件并取消注释SSL代码行并重新构建它,参考以下主题:http://forums.opensuse.org/english/get-technical-help-here/applications/488962-opensuse -python-的OpenSSL 2.HTML

Answer 1

OSX +自制软件用户:

您可以获得配方的最新更新:

brew reinstall python

但是如果你仍然遇到问题,例如你可能已经升级了操作系统,那么你可能需要先获得最新的openssl.您可以从以下位置查看使用的版本和位置:

openssl version -a
which openssl

要获得最新的openssl:

brew update
brew install openssl
brew link --overwrite --dry-run openssl  # safety first.
brew link openssl --overwrite

这可能会发出警告:

bash-4.3$ brew link --overwrite --dry-run openssl
Warning: Refusing to link: openssl Linking keg-only openssl means you may end up linking against the insecure, deprecated system OpenSSL while using the headers from Homebrew's openssl. 
Instead, pass the full include/library paths to your compiler e.g.: 
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

附注:此警告表示对于其他应用,您可能需要使用

export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include

然后重新编译python:

brew uninstall python
brew install python --with-brewed-openssl

或者对于python 3

brew uninstall python3
brew install python3 --with-brewed-openssl

Answer 2

如果需要SSL支持,则需要在构建Python之前安装OpenSSL头文件.在Debian和Ubuntu上,它们位于一个名为的包中libssl-dev.您可能需要更多依赖项,如此处所述.

这可能是由于升级到小牛队造成的.这就是我修复它的方法.

更新OpenSSL

#make a copy of the existing library, just in case
sudo cp /usr/bin/openssl /usr/bin/openssl.apple

# update openssl 
brew update
brew install openssl
brew link --force openssl

# reload terminal paths
hash -r

重新安装Python

Python 3

brew uninstall python3

brew install python3 --with-brewed-openssl

Python 2

brew uninstall python

brew install python --with-brewed-openssl

这个答案整合了我发现的所有Stack Exchange答案和评论,主要基于Apple Stack Exchange的答案.

Answer 4

您需要在make之前安装OpenSSl并安装Python来解决问题.

在Centos上:

yum install openssl openssl-devel -y

^资源

Answer 5

即使在确认我的PATH等之后,我在Mac OSX上遇到了这个问题.

做了一个; 点击卸载virtualenv然后安装virtualenv它似乎现在有效.

当时我强迫brew连接openssl,取消关联它和virtualenv似乎仍然有用但也许那是因为它最初是在我重新安装时链接的.

Answer 6

对我来说这个问题的另一个症状是,如果我进入我的virtualenv的python控制台并且import ssl它会错误.原来我的virtualenv没有使用brewpython版本,只是我机器上的默认安装.不知道为什么默认安装突然停止工作,但这是我如何修复它的问题:

• rmvirtualenv myvirtualenv
• brew update
• brew reinstall python
• mkvirtualenv -p /usr/local/Cellar/python/whatever_version_number/bin/python myvirtualenv
