Question

是否有一些魔术来获取pipenv来安装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"

我尝试添加并删除pyscopg2-binary的安装，但这没有什么区别。我在运行OSX 10.14.4的Mac上。

这是我运行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!

我尝试了推荐的命令，例如pipenv clean，甚至尝试从头开始在新目录中进行所有操作，没有尝试Pipfile，但是没有运气。当我尝试直接通过pipenv install pyscopg2安装psycopg2时，结果相同。

Answer 1

对于我来说，要在WSL2下运行Ubuntu 20.04，我必须遵循here

的说明。

sudo apt install python3-dev libpq-dev

然后我运行pipenv shell来启动我的环境。

然后运行：pip install psycopg2没有问题。

Answer 2

您无法构建它。尝试安装此软件：https://pypi.org/project/psycopg2-binary/

Answer 3

我只是遇到了这个确切的问题。我必须删除当前的virtualenv并重建它。

pipenv --rm
rm Pipfile.lock
pipenv install

Answer 4

扩大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，但首先跳过通过pipenv install --skip-lock创建的锁定文件，然后使用pipenv lock重新创建锁定文件

pipenv始终无法安装pyscopg2
