Pipenv 无法使用 psycopg2-binary 锁定

Question

我正在尝试为 Django 开发创建一个虚拟环境。我能够在另一个项目中成功安装 psycopg2-binary，但无法重现成功的安装。

环境：

Python 3.8.1
Pipenv版本2018.11.26

安装步骤：

mkdir test && cd test
pipenv install django psycopg2-binary==2.8.4

上运行:

Installing psycopg2-binary==2.8.4…
Adding psycopg2-binary to Pipfile's [packages]…
Installation Succeeded
Pipfile.lock (24bc11) out of date, updating to (a6086c)…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Locking Failed!

有没有人遇到过类似的问题？我倾向于它是我如何尝试解决 pipenv 锁定的问题，因为我昨天没有遇到这个问题。

Answer 1

我使用这个线程解决了这个问题：https://github.com/pypa/pipenv/issues/3468

普遍认为 pipenv 不支持 3.8.1，我已经降级到 3.7.6 并将使用它直到提供支持。

Answer 2

在尝试安装之前先安装 postgresql 和 postgresql-contrib psycopg2-binary/psycopg2 解决了我的问题。值得一试。

sudo apt install postgresql postgresql-contrib

Pipenv 无法使用 psycopg2-binary 锁定
