pylint 和 astroid AttributeError: 'Module' 对象没有属性 'col_offset'

如何解决pylint 和 astroid AttributeError: 'Module' 对象没有属性 'col_offset'

使用 pylint 版本 2.9.0 和 2.9.3 时失败。使用版本 2.8.3 它仍然有效。

请参阅所提供链接下的 GitHub-issue。

src/packages/project/requirements.txt 包含：

awswrangler==2.8.0

simple_salesforce==1.0.0

对产生相同错误的不同尝试进行编辑：

1. 安装pylint=2.9.3
2. 安装 astroid 和 pylint（最新版本，无版本规范）
3. 在构建过程中（在 AWS test-buildspec.yml 中）通过 astroid 安装 pylint 和 astroid 并将 pip install --upgrade astroid 升级到最新版本（建议 {{3} })

解决方法

您似乎在 pylint 2.9 中发现了错误/崩溃，您可以打开问题 here。您可以在修复期间降级到 2.8.3。

,

感谢@Pierre.Sassoulas 的工作，此问题已得到解决（请参阅 here）。

在证明 pylint - 和 astroid - 版本的以下组合可以很好地协同工作而不会产生 OP 错误后，对 GitHub-project 进行了新的提交以修复问题：

pip install pylint==2.9.3
pip install git+git://github.com/PyCQA/astroid.git@c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid

从这里开始，安装最新版本的 pylint 和 astroid 应该不会再次出现问题。但是，如果问题再次出现，我会在此处通知您。
