python - pipenv 始终无法安装 psycopg2

Question

是否有一些魔术可以让 pipenv 安装 psycopg2？

我的 Pipfile 看起来像这样:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
django = "==2.1.3"
psycopg2 = "*"

[dev-packages]

[requires]
python_version = "3.6"

我试过添加和删除 pyscopg2-binary 的安装，但没有任何区别。我在运行 OSX 10.14.4 的 Mac 上。

这是我在运行 pipenv install 后得到的输出:

An error occurred while installing psycopg2==2.8.3 --hash=sha256:128d0fa910ada0157bba1cb74a9c5f92bb8a1dca77cf91a31eb274d1f889e001 --hash=sha256:227fd46cf9b7255f07687e5bde454d7d67ae39ca77e170097cdef8ebfc30c323 --hash=sha256:2315e7f104681d498ccf6fd70b0dba5bce65d60ac92171492bfe228e21dcc242 --hash=sha256:4b5417dcd2999db0f5a891d54717cfaee33acc64f4772c4bc574d4ff95ed9d80 --hash=sha256:640113ddc943522aaf71294e3f2d24013b0edd659b7820621492c9ebd3a2fb0b --hash=sha256:897a6e838319b4bf648a574afb6cabcb17d0488f8c7195100d48d872419f4457 --hash=sha256:8dceca81409898c870e011c71179454962dec152a1a6b86a347f4be74b16d864 --hash=sha256:b1b8e41da09a0c3ef0b3d4bb72da0dde2abebe583c1e8462973233fd5ad0235f --hash=sha256:cb407fccc12fc29dc331f2b934913405fa49b9b75af4f3a72d0f50f57ad2ca23 --hash=sha256:d3a27550a8185e53b244ad7e79e307594b92fede8617d80200a8cce1fba2c60f --hash=sha256:f0e6b697a975d9d3ccd04135316c947dd82d841067c7800ccf622a8717e98df1! Will try again.

我已经尝试了推荐的命令，例如 pipenv clean，甚至尝试了在新目录中从头开始的所有操作，没有 Pipfile，但没有成功。当我尝试通过 pipenv install pyscopg2 直接安装 psycopg2 时，结果相同。

扩展 heemayl 的评论，我最终需要运行:

brew unlink openssl && brew link openssl --force

然后设置一堆环境变量:

echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

然后删除 Pipfile.lock 并重新安装所有内容，但最初通过 pipenv install --skip-lock 跳过锁定文件创建，然后重新创建锁定文件pipenv 锁
