無法安裝pyopenssl（python27）

Question

我是編程新手。 我正在按照要求我使用“ pip install pyopenssl”命令安裝pyopenssl的步驟進行操作，但由於出現錯誤vc9.0而失敗，我下載了VCfor python27的VC，但仍然出現錯誤。這是我在cmd中的日志

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

安裝適當的OpenSSL應用后。 版本，您應該復制所有標頭

C:\OpenSSL-Win32\include\openssl. 

至

C:\Pyhton27\inclide

和所有庫

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

Answer 2

C:\Python27\Scripts>pip install pyopenssl

我不確定，但看來您已經安裝了較舊的pyopenssl版本，可以使用

pip install pyopenssl --upgrade

卸載舊版本並安裝新版本。

如果您能告訴我輸入命令后會發生什么，也許我可以提供更多幫助

pip install pyopenssl 

現在在cmd窗口中。

Answer 3

pyOpenSSL取決於pyca / cryptography。 pyca / cryptography附帶了Windows編譯輪，它將繞過此問題（並消除了對編譯器/ OpenSSL標頭/庫的需要），但您需要將pip升級到最新版本。 python -m pip install -U pip將執行此操作（由於打開文件鎖定，在Windows上pip install -U pip有問題）

Answer 4

就我而言，以下策略對我有效。

pip uninstall pyOpenSSL
pip install pyopenssl --upgrade
