如何在 Django 項目中創建 requirements.txt 文件？

Question

我一直在嘗試從 Pycharm 終端創建一個 requirements.txt 文件，但它也添加了所有不必要的包。 我應該怎么做才能只顯示使用過的包？ 謝謝，requirements.txt：

Answer 1

看看這個蛇食

特別是在 python 項目中查找並列出導入語句的命令sfood-imports

所以它不取決於您的環境，而是取決於您編寫的代碼

Answer 2

pip freeze > requirements.txt

Answer 3

安裝freeze ：

python -m pip freeze 

並創建文件：

pip freeze > requirements.txt
