我使用 pip freeze > requirements.txt 创建了 requirements.txt。一些模块显示@file.....而不是版本#。这是什么意思，为什么会显示？
conda :4.8.3
这是 requirements.txt 的结果。例如astroid、flask-admin、matplotlib 在下方显示“@file”

最佳答案
这是从 VCS 存储库安装软件包的特殊语法(自 pip 19.1 起受支持):
package_name @ git+https://githost/<repo>.git@<commit_id>
关于python - 为什么 pip 需求文件包含 "@file"而不是版本号？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62586878/
