Checkov 错误：AttributeError：类型对象“Lark”没有属性“_load_from_dict”

问题描述

我在运行 checkov 时遇到了一些问题，我不熟悉 python 库，谁能给我一些提示？

这在某些机器上工作正常，但在这台机器上尤其如此......

在 CentOS 中运行：

$ checkov --directory cdk.out

Traceback (most recent call last):
  File "/usr/local/bin/checkov",line 2,in <module>
    from checkov.main import run
  File "/usr/local/lib/python3.6/site-packages/checkov/main.py",line 22,in <module>
    from checkov.terraform.plan_runner import Runner as tf_plan_runner
  File "/usr/local/lib/python3.6/site-packages/checkov/terraform/plan_runner.py",line 11,in <module>
    from checkov.terraform.context_parsers.registry import parser_registry

    from checkov.terraform.context_parsers.parsers import *

    import hcl2
  File "/usr/local/lib/python3.6/site-packages/hcl2/__init__.py",line 5,in <module>
    from .api import load,loads
  File "/usr/local/lib/python3.6/site-packages/hcl2/api.py",line 4,in <module>
    from hcl2.parser import hcl2
  File "/usr/local/lib/python3.6/site-packages/hcl2/parser.py",line 53,in <module>
    hcl2 = Lark_StandAlone(transformer=DictTransformer())
  File "/usr/local/lib/python3.6/site-packages/hcl2/lark_parser.py",line 8,in Lark_StandAlone
    return Lark._load_from_dict(DATA,MEMO,**kwargs)
AttributeError: type object 'Lark' has no attribute '_load_from_dict'

解决方法

将 python 从 3.6 升级到 3.8 并重新安装 checkov 后，它工作得很好。
