pip 为加密包构建轮子时出现错误。
错误:
LINK : fatal error LNK1181: cannot open input file 'libssl.lib'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x86\\link.exe' failed with exit status 1181

我已经安装OpenSSL和设置环境变量中所建议的这个帖子却问题依旧。我的设置细节:

TLDR;
尝试使用 cryptography==3.1.1
细节:
这发生Python 3.9.0在Windows 10PC上。我在requirements.txt中有以下内容
cryptography==2.8
Run Code Online (Sandbox Code Playgroud)
我删除了这个版本,只在如下的requirements.txt文件中保留了密码学
cryptography
Run Code Online (Sandbox Code Playgroud)
保存了requirements.txt然后我跑了
pip install -r requirements.txt
Run Code Online (Sandbox Code Playgroud)
它安装成功。然后我通过运行以下命令冻结requirements.txt
pip freeze > requirements.txt
Run Code Online (Sandbox Code Playgroud)
然后requirements.txt得到更新cryptography==3.1.1

也有这个问题。如果您使用的是 alpine,请确保已安装加密的所有依赖项。在我的情况下,货物包裹丢失并导致了问题。
sudo apk add gcc musl-dev python3-dev libffi-dev openssl-dev cargo

在我的情况下(Windows 10 + conda)更新 pip 解决了这个问题:
python -m pip install --upgrade pip

我在 macOS Monterey(版本 12.2.1)Apple M1 Pro 上遇到了这个问题。我遵循了加密安装文档,它帮助我解决了问题。
brew install openssl@1.1 rust
env CRYPTOGRAPHY_SUPPRESS_LINK_FLAGS=1 LDFLAGS="$(brew --prefix openssl@1.1)/lib/libssl.a $(brew --prefix openssl@1.1)/lib/libcrypto.a" CFLAGS="-I$(brew --prefix openssl@1.1)/include" pip3 install cryptography

您可以使用最新版本
python3 -m pip install --no-use-pep517 cryptography

在arm32v7上使用ubuntu:18.04为我工作(而不是按照错误消息的建议安装完整的rust编译器和构建必需品,或升级pip(对我的armbian上的ubuntu:18.04没有影响))
碰到这个问题,解决方法其实就在pip尝试在加密前安装openssl时的消息中:
generating cffi module 'build/temp.linux-x86_64-3.7/_openssl.c'
running build_rust

只需运行 pip update 命令似乎对我有用:
pip install -U pip
