Question

当我试图导入pylint.checkers时，会得到以下错误：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-3-d869f1bd3d2f> in <module>
----> 1 pl.checkers

AttributeError: module 'pylint' has no attribute 'checkers'

当我尝试dir(pylint)时，我得到：

In [8]: dir(pylint)
Out[8]:
['__all__',
 '__builtins__',
 '__cached__',
 '__doc__',
 '__file__',
 '__loader__',
 '__name__',
 '__package__',
 '__path__',
 '__pkginfo__',
 '__spec__',
 '__version__',
 'run_epylint',
 'run_pylint',
 'run_pyreverse',
 'run_symilar',
 'sys']

另一个bug :我在安装pylint时遇到了以下警告：

astroid 2.4.2 requires lazy-object-proxy==1.4.*, but you'll have lazy-object-proxy 0.0.0 which is incompatible.

你能帮帮我吗？

Answer 1

问题解决了。我不知道为什么，但是：

>>> import pylint.checkers
>>> dir(pylint.checkers
... )
['BaseChecker', 'BaseTokenChecker', '__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', 'base_checker', 'initialize', 'register_plugins', 'table_lines_from_stats']
>>>

重新启动可能是必要的。
