Question

嘗試安裝 package，例如pytorch

pip install torch / pip install -U torch

    -----------------------------------------

正如我所相信json-server的入口點導致了這個問題。 據我所知， json-server不是 python package 而是 CLI 工具。

我假設- in json-server=json-server.cli:main來自我從這篇文章中讀到的內容

我能做些什么呢？

Answer 1

package 有兩個問題。

1. 主要的可導入目錄名為json-server 。 這是一個錯誤， -在 Python 名稱中被禁止。 它必須重命名為json_server 。

2. 該腳本是使用該禁止模塊聲明的。 它必須固定為

[tool.poetry.scripts]
json-server = "json_server.cli:main"

請報告這些錯誤。
