无法安装pyopenssl（python27）

Question

我不懂编程。 我是按照下面的步骤要求我使用“pip install pyopenssl”命令安装pyopenssl，但是失败了，错误是vc9.0 required我下载了vcforpython27，但我仍然收到一个错误

C:\Python27\Scripts>pip install pyopenssl
You are using pip version 7.0.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip'         `command.`

Answer 1

pyOpenSSL依赖于pyca/加密技术。pyca/cryptography为Windows提供了编译的轮子，它可以绕过这个问题（并且不需要编译器/OpenSSL头/库），但是您需要将pip升级到更新的版本。python -m pip install -U pip将完成此操作（pip install -U pip在Windows上由于打开文件锁定而出现问题）

Answer 2

C:\Python27\Scripts>pip install pyopenssl

我不确定，但似乎您已经安装了旧版本的pyopenssl，您可以使用

^{pr2}$

卸载旧版本并安装新版本。在

如果你能告诉我如果你输入命令会发生什么，也许我能提供更多帮助

pip install pyopenssl 

现在在cmd窗口中。在

Answer 3

安装适当的OpenSSL应用程序后。应该从中复制所有标题的版本

C:\OpenSSL-Win32\include\openssl. 

到

^{pr2}$

所有的LIB

C:\OpenSSL-win32\lib to C:\Python27\Lib.
