在我的本地环境中 flake8 --verbose 工作，但是当我运行 pipenv run flake8 --verbose 时，我的 virtualenv 和结果是：

Segmentation fault (core dumped)

我无法获取 virtualenv 的核心转储日志。

flake8 版本：

3.7.8 (mccabe: 0.6.1, pycodestyle: 2.5.0, pyflakes: 2.1.1) CPython 3.7.0 on Linux

所有代码都在 docker 容器中运行，使用 python 3.7.0。

【问题讨论】：

flake8 --bug-report: ``` { "dependencies": [ { "dependency": "entrypoints", "version": "0.3" } ], "platform": { "python_implementation": " CPython”，“python_version”：“3.7.0”，“system”：“Linux”}，“plugins”：[{“is_local”：false，“plugin”：“mccabe”，“version”：“0.6.1 " }, { "is_local": false, "plugin": "pycodestyle", "version": "2.5.0" }, { "is_local": false, "plugin": "pyflakes", "version": "2.1 .1" } ], "版本": "3.7.8" } ```
我建议在项目问题跟踪器上报告错误，而不是在 StackOverflow 上。 gitlab.com/pycqa/flake8/issues
已经这样做了

标签： python-3.x virtualenv pipenv flake8

【解决方案1】：

根据flake8 repository中的问题，非官方python版本中存在一些无法解释的错误。我通过创建一个新的虚拟环境来修复它，使用 pyenv 构建的 python3.7.5。
