我在Windows上的Wing IDE内部运行PyLint。我有一个子目录(包)在我的项目和包内，我从顶层导入一个模块，即。
__init__.py
myapp.py
one.py
subdir\
__init__.py
two.py
在two.py中，我导入了一个，这在运行时工作得很好，因为顶层目录(myapp.py从其中运行)在Python路径中。然而，当我在two.py上运行PyLint时，它会给我一个错误:
F0401: Unable to import 'one'
我怎么解决这个问题?
当前回答
我找到了一个很好的答案。编辑pylintrc并在master中添加以下内容
init-hook="import imp, os; from pylint.config import find_pylintrc; imp.load_source('import_hook', os.path.join(os.path.dirname(find_pylintrc()), 'import_hook.py'))"
其他回答
关键是将你的项目目录添加到sys。路径而不考虑env变量。
对于使用VSCode的人，如果你的项目有一个基本目录，这里有一个简单的解决方案:
[MASTER]
init-hook='base_dir="my_spider"; import sys,os,re; _re=re.search(r".+\/" + base_dir, os.getcwd()); project_dir = _re.group() if _re else os.path.join(os.getcwd(), base_dir); sys.path.append(project_dir)'
让我来解释一下:
re.search (r”。+\/" + base_dir, os.getcwd()).group():根据编辑文件查找基目录 Os.path.join (os.getcwd()， base_dir):添加CWD到系统。满足命令行环境的路径
供你参考，这是我的.pylintrc:

我发现这在我的本地.pylintrc文件和pipenv虚拟环境中工作得很好:
[MASTER]
init-hook='import site; sys.path += site.getsitepackages()'

I have been struggling with this a lot and eventually found out something that was not described here. Here are my 2 cents to this issue: I am using VS Code on Windows, using virtual env. For some reasons, the pylint executable is called epylint and not pylint. In my script or from CLI prompt, I was running pylint ./xxx and the system was launching a pylint it found somewhere else but not the appropriate one. I just added an e in my shell script and my 'Unable to import' issues eventually vanished.
首先，进入VS Code，然后按“ctrl + shift + p”
然后搜索settings.json
然后将下面的代码粘贴到设置中。我希望问题能够解决。
{
"python.pythonPath": "venv/bin/python",
"python.linting.pylintPath": "venv/bin/pylint"
}
在这两个目录中都有一个空的__init__.py文件来让python知道dirs是模块吗?
当你不是从文件夹中运行时(比如可能从pylint的文件夹中运行，尽管我没有用过)，基本的大纲是:
topdir\
__init__.py
functions_etc.py
subdir\
__init__.py
other_functions.py
这就是python解释器如何在不引用当前目录的情况下感知模块，因此如果pylint从它自己的绝对路径运行，它将能够以topdir的身份访问functions_etc.py。Functions_etc或topdir.subdir。other_functions，前提是topdir在PYTHONPATH上。
UPDATE: If the problem is not the __init__.py file, maybe just try copying or moving your module to c:\Python26\Lib\site-packages -- that is a common place to put additional packages, and will definitely be on your pythonpath. If you know how to do Windows symbolic links or the equivalent (I don't!), you could do that instead. There are many more options here: http://docs.python.org/install/index.html, including the option of appending sys.path with the user-level directory of your development code, but in practice I usually just symbolically link my local development dir to site-packages - copying it over has the same effect.
