这是我第一次尝试使用pip-compilefrompip-tools。

Django 项目的基本设置在main/settings/base.py. 我将此部分添加为pip-tools：

install_requires = [
    'django-oscar>=3.0.2,<4.0.0',
    'boto3==1.17.27',
    'psycopg2-binary==2.8.6',
    'pycountry==20.7.3',
]

pip-compile当我尝试使用它时会爆炸。这怎么可能解决？

$ pip-compile main/settings/base.py

更新 1：我在本节中遇到相同的错误：

install_requires = [
]

更新 2：我制作了一个文件，requirements.in如下所示：

django-oscar>=3.0.2,<4.0.0
boto3==1.17.27
psycopg2-binary==2.8.6
pycountry==20.7.3

...并requirements.txt正确生成：

pip-tools解析是否损坏setup.py？
