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

当前回答

如果你正在dockerizing你的python应用程序，你的Dockerfile需要有这样的东西:

从python 3.7高山

执行apk add——update alpine-sdk && apk add libffi-dev openssl-dev

运行pip install cryptography

2020-09-10 19:12:32

其他回答

如果您正在使用python3，则需要安装python3-dev。这解决了我的问题sudo apt-get安装python3-dev。

2016-09-12 20:03:42

这适用于El Capitan与MacPorts:

$ sudo port install openssl
$ env LDFLAGS="-L/opt/local/lib" CFLAGS="-I/opt/local/include" pip install cryptography
2016-09-27 10:12:22

在运行安装之前，必须升级PIP

2021-04-08 17:29:00

显然，在OSX的最新版本中，这可能是由于苹果发布了他们自己的OpenSSL版本，它不能与加密库一起工作。

最新版本的密码学库附带了它们自己的本机依赖项，但要获得它们，您需要升级pip，可能还需要升级virtual env。所以对我来说，解决方案是:

pip install --upgrade --force-reinstall pip virtualenv
2016-03-08 12:37:15

我如何解决“无法清理加密的构建目录” (我从谷歌来到这里导致这个错误。)

注意:使用virtualenv

TL; diana:

我的文件/etc/apt/sources.我的debian 8的列表配置不正确。

解释:

我想安装paramiko。 Paramiko需要密码学。

我得到了这些错误: 首先用PIP安装密码:

(...)
  ----------------------------------------
  Failed cleaning build dir for cryptography

    ----------------------------------------
Command "/home/myuser/pyenvs/testo/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-HXWKAO/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-WjqY6V-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/myuser/pyenvs/testo/include/site/python2.7/cryptography" failed with error code 1 in /tmp/pip-build-HXWKAO/cryptography/

然后用sudo apt-get install build-essential:

Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 build-essential : Depends: libc6-dev but it is not going to be installed > or
                            libc-dev
                   Depends: gcc (>= 4:4.4.3) but it is not going to be installed
                   Depends: g++ (>= 4:4.4.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

(与OP的错误不完全相同，但我最终会在这里提供帮助)

解决:

在测试了几乎每个帖子的每个命令后，我最终决定继续下去 https://wiki.debian.org/SourcesList 并复制粘贴我足够的配置文件/etc/apt/sources.list

然后:

须道资质更新

然后

Sudo apt-get install build-essential libssl-dev libffi-dev python-dev

然后

PIP安装密码
