警告：“news”是 pyproject.toml 中定义的入口点，但它没有作为脚本安装。你可能会得到不正确的`sys.argv[0]`

Question

• 我正在尝试使用 docker compose 在 docker 中运行我的基于诗歌的 python 项目
• 当我运行该应用程序时，它可以工作，但它给了我这个警告

ch_news_dev_python          | Warning: 'news' is an entry point defined in pyproject.toml, but it's not installed as a script. You may get improper `sys.argv[0]`.
ch_news_dev_python          | 
ch_news_dev_python          | The support to run uninstalled scripts will be removed in a future release.
ch_news_dev_python          | 
ch_news_dev_python          | Run `poetry install` to resolve and get rid of this message.

有人可以告诉我如何摆脱这个警告吗？

更新1

即使删除 --no-root 后仍收到警告

Answer 1

该错误与诗歌中声明的入口点有关 在你的文件 pyproject.toml 中：

[tool.poetry.scripts]
news = "news.__main__:app"

声明入口点后，必须执行命令

poetry install

在您的终端中

Answer 2

项目中 src 目录的名称应与 toml 中的名称相同（pyproject.toml 的第 4 行）

所以你应该将你的 src 目录重命名为“news”。或者（作为一个选项）您可以将 toml 第 4 行中的 'name = "news"' 更改为 'name = "src"'。这对我有用。

Answer 3

您的 docker 文件显示，您正在使用

poetry install

标志运行

--no-root

。入口点是包的一部分，因此只有在安装包时才会安装它们。您必须在没有

poetry install

标志的情况下运行

--no-root

。

我看不出你有什么理由使用

--no-root

。在不安装项目本身的情况下，您的

import

语句能够正常工作只是运气好。
