pylint and astroid AttributeError: 'Module' object has no attribute 'col_offset'

Question

使用失败 pylint version 2.9.0 and 2.9.3. With version 2.8.3 但它仍然有效。

请参阅提供的 link 下的 GitHub-issue。

本测试环境的requirements.txt - 文件包含：

astroid
src/packages/project/requirements.txt
pycodestyle
pylint
pylint_junit
pytest
pytest-cov
yapf

with src/packages/project/requirements.txt 包含：

awswrangler==2.8.0
babel==2.9.1
boto3==1.17.77
botocore==1.20.77
category-encoders==2.2.2
joblib==1.0.1
markdown==3.3.4
matplotlib==3.3.4
openpyxl==3.0.7
pandas==1.1.5
pyarrow==4.0.0
pytz==2021.1
requests==2.25.1
scikit-learn==0.24.2
simple_salesforce==1.0.0

编辑产生相同错误的不同尝试：

1. 正在安装pylint=2.9.3
2. 正在安装 astroid 和 pylint（最新版本，无版本说明）
3. 安装 astroid 和 pylint 并在构建过程中通过 pip install --upgrade astroid（建议here)

Answer 1

看来你在pylint2.9中发现了一个bug/crash，你可以开一个issuehere。您可以在修复期间降级到 2.8.3。

Answer 2

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

在证明以下 pylint - 和 astroid - 版本的组合可以很好地协同工作而不会产生 OP 错误后，已对 GitHub-project 进行新的提交以解决问题：

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 应该不会再出现这个问题。但是，如果问题 returns，我会在这里通知您。
