我正在尝试在cygwin中安装psycopg2但还没有成功.错误是: -

我一直在关注文档，直到我安装了 requirements.txt 文件。尝试安装第 6 行“psycopg2==2.5.3”时总是失败。这是消息——

我的项目正在运行 postgreSQL，在我将系统升级到 ubuntu 16.04 并再次克隆该项目后，我无法安装特定的包。

我也尝试清除 postgresql 和 psycopg2 但无法安装它

我在我的旧笔记本电脑上设置了一个项目，并在本地安装了 Postgresql，并使用 Poetry 作为包管理器。现在我搬到另一台笔记本电脑上。在这一项上，我想使用 Docker 中的 Postgres，所以我没有安装它。但是当我运行poetry install从文件设置项目时poetry.lock，它无法安装 Psycopg2 并出现错误：

Error: pg_config executable not found.

据我搜索，它需要在本地安装 Postgres。那么，如何使用 Docker 中的 Postgres 从锁定文件安装 Psycopg2？

在 Ubuntu 22.04 上看到这个，它有 python 3.10

• pipenv 安装 psycopg2
• pip 安装 psycopg2
