python – 导入另一个文件错误

我的文件夹/文件structrue是：

testpkg/test/__init__.py;
testpkg/test/test1.py
testpkg/test/test2.py
testpkg/setup.py

testpkg / test / __ init__.py文件为空.
testpkg / test / test1.py文件内容：

class Test1:
    def __init__(self, name):
        self.name = name

    def what_is_your_name(self):
        print(f'My name is {self.name}')

testpkg / test / test2.py文件内容：

from .test1 import Test1


def main():
    t = Test1('me')
    t.what_is_your_name()

if __name__ == '__main__':
    main()

/testpkg/setup.py内容：

from setuptools import setup

setup(name='test',
      version='0.1',
      packages=['test'],
      entry_points={
          'console_scripts': [
              'test_exec = test.test2:main'
          ]
      }
      )

我无法直接调试/运行test2.py脚本,因为它给了我错误：

» python test/test2.py
Traceback (most recent call last):
  File "test/test2.py", line 1, in <module>
    from .test1 import Test1
ModuleNotFoundError: No module named '__main__.test1'; '__main__' is not a package

但是当我用pip install -U安装它时.

有用：

» pip install -U .
Processing /home/kossak/Kossak/files_common/PythonProjects/testpkg
Installing collected packages: test
  Found existing installation: test 0.1
    Uninstalling test-0.1:
      Successfully uninstalled test-0.1
  Running setup.py install for test ... done
Successfully installed test-0.1

» test_exec
My name is me

问题是：如何正确编写test2.py以便它可以在两种方式下工作 – 直接(因此我可以在PyCharm中调试它或者只运行python test2.py)并在安装测试包之后？我试过换线：

from .test1 import Test1

至

from test1 import Test1

(删除点)

我可以从命令行运行test2.py,但是在安装之后,我的脚本“test_exec”给了我错误：

Traceback (most recent call last):
  File "/home/kossak/anaconda3/bin/test_exec", line 11, in <module>
    load_entry_point('test==0.1', 'console_scripts', 'test_exec')()
  File "/home/kossak/anaconda3/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg/pkg_resources/__init__.py", line 565, in load_entry_point
  File "/home/kossak/anaconda3/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg/pkg_resources/__init__.py", line 2598, in load_entry_point
  File "/home/kossak/anaconda3/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg/pkg_resources/__init__.py", line 2258, in load
  File "/home/kossak/anaconda3/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg/pkg_resources/__init__.py", line 2264, in resolve
  File "/home/kossak/anaconda3/lib/python3.6/site-packages/test/test2.py", line 1, in <module>
    from test1 import Test1
ModuleNotFoundError: No module named 'test1'

解决方法:

尝试像这样导入它：从test.test1导入Test1
