使用PIP和setup.py安装Python加密包失败

当我试图通过pip install Cryptography或从他们的网站下载包并运行Python setup.py安装Python密码学包时，我得到以下错误:

我发现了其他egg_info错误帖子(这里和这里)，但那里提供的解决方案不能解决我的问题。另外，我可以通过PIP安装其他包。

PIP版本1.5.4 setuptools版本2.2

用命令点赞更新PIP版本:

easy_install -U pip Python-m PIP install——升级PIP

只需选择一个来更新。

我也犯了这个错误。在安装openSSL后仍然出现这个错误，我最终尝试从https://pypi.python.org/pypi/cryptography/0.2.2#downloads的wheel文件安装。它工作!

2014-05-29 20:41:57

升级pip版本解决了这个问题

PIP安装——升级PIP(适用于mac/linux发行版)

2021-10-14 12:53:17

这两个命令帮我解决了问题:

brew install openssl
brew link openssl --force

在埃尔卡皮坦，这招很管用

brew install pkg-config libffi openssl
env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography
