我有一个 click 项目，它在任何地方都不使用/不需要 Django，但在运行 prospector 作为静态分析的一部分时会抛出这个奇怪的错误
命令
prospector -I __init__.py --strictness veryhigh --max-line-length 120 src/
错误
Line: 1
pylint: django-not-available / Django is not available on the PYTHONPATH
项目/代码中的任何地方都没有 django 的引用。我对 python 相当陌生，我在这里遗漏了一些明显的东西吗？

最佳答案
正如我在评论中所说，我认为探矿者和 requirement-detector 有一个错误.
我只需在空的 virtualenv 中安装 prospector 1.1.7 就可以重现该问题:
$ pip freeze
astroid==2.2.5
dodgy==0.1.9
isort==4.3.21
lazy-object-proxy==1.4.3
mccabe==0.6.1
pep8-naming==0.4.1
prospector==1.1.7
pycodestyle==2.3.1
pydocstyle==4.0.1
pyflakes==1.6.0
pylint==2.3.1
pylint-celery==0.3
pylint-django==2.0.10
pylint-flask==0.6
pylint-plugin-utils==0.6
PyYAML==5.1.2
requirements-detector==0.6
setoptconf==0.2.0
six==1.13.0
snowballstemmer==2.0.0
typed-ast==1.4.0
wrapt==1.11.2
然后创建一个虚拟代码:
$ cat src/__init__.py
print('something')
运行探矿者时我遇到了同样的错误:
$ prospector src/
/home/sma/.pyenv/versions/3.7.3/envs/58918408_so/lib/python3.7/site-packages/pycodestyle.py:113: FutureWarning: Possible nested set at position 1

自 prospector issue 245和 pylint django PR 137 Django 成为 pylint-django 的额外依赖项。
但是在没有安装 django 的情况下运行它仍然会返回一条消息:
$ pylint --load-plugins pylint_django src
************* Module src
src/__init__.py:1:0: C0111: Missing module docstring (missing-docstring)
src/__init__.py:1:0: F5101: Django is not available on the PYTHONPATH (django-not-available)
------------------------------------------------------------------
Your code has been rated at 0.00/10 (previous run: 0.00/10, +0.00)
我的猜测是探矿者捕获该消息并在直接运行时返回它，即使用依赖项自动检测。
对我来说，这似乎是两个库之间的错误/集成问题，但需要来自项目之一的贡献者/维护者的确认。
否则@Thaveedu，解决方法是禁用依赖项自动检测，因为在您的情况下，您可能不关心 django、flask 或 celery:
$ prospector --no-autodetect src/
/home/sma/.pyenv/versions/3.7.3/envs/58918408_so/lib/python3.7/site-packages/pycodestyle.py:113: FutureWarning: Possible nested set at position 1
