为什么客户的python包无法导入? [英] Why customer python package can not be imported?
问题描述
我创建了自己的名为 jjnsegutils
的python程序包,并将其上传到Pypi网站.但是,通过 pip install jjnsegutils
成功安装它之后,我仍然无法导入它.错误显示: ModuleNotFoundError:没有名为"jjnsegutils"的模块
.
I created my own python package named jjnsegutils
and upload it to Pypi website. But after I successfully install it by pip install jjnsegutils
, I still can not import it. Error shows: ModuleNotFoundError: No module named 'jjnsegutils'
.
有关整个过程的详细信息如下.
Details about the whole procedure are as follows.
我的包裹的结构是:
jjnsequtils
├─ __init__.py
├─ myutil
├─ __init__.py
├─ myutil.py
├─ LICENSE
├─ README.md
├─ setup.py
两个 __init__.py
文件是空的.
在我的 setup.py
中:
import setuptools
with open("README.md", "r") as fh:
long_description = fh.read()
setuptools.setup(
name="jjnsegutils", # Replace with your own username
version="0.0.10",
author="Jingnan",
author_email="jiajingnan2222@gmail.com",
description="A package of common utilities for Medical images segmentation and evaluation.",
long_description=long_description,
long_description_content_type="text/markdown",
url="https://github.com/Ordgod/jjnsegutils",
packages=setuptools.find_packages(),
classifiers=[
"Programming Language :: Python :: 3",
"License :: OSI Approved :: MIT License",
"Operating System :: OS Independent",
],
python_requires='>=3.6',
)
如何生成软件包?
我使用命令 python setup.py sdist bdist_wheel
生成分发文件.记录信息
:

adding 'jjnsegutils-0.0.10.dist-info/RECORD'
removing build/bdist.linux-x86_64/wheel
如何分发包裹?
我使用命令 twine upload dist/*
将 dist
中的文件上传到Pypi.
How do I distribute the package?
I use command twine upload dist/*
to upload the files in dist
to Pypi.
我使用命令 pip install jjnsegutils
将其安装到由conda创建的名为 py37
的我自己的环境中.它显示了
I use command pip install jjnsegutils
to install it into my own environment named py37
created by conda. It shows
Collecting jjnsegutils
Downloading jjnsegutils-0.0.10-py3-none-any.whl (11 kB)
Installing collected packages: jjnsegutils
Successfully installed jjnsegutils-0.0.10
然后我在终端中输入 $ python
进入python交互式终端.并输入:
Then I type $ python
in my terminal to enter the python interractive terminal. and type:
>>> import jjnsegutils
但是它显示:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'jjnsegutils'
我试图诊断出什么问题?
我通过命令 $ pip show jjnsegutils
检查了软件包,它显示:
What actions I have tried to diagnosize the issue?
I checked the package by command $ pip show jjnsegutils
, it shows:
Name: jjnsegutils
Version: 0.0.10
Summary: A package of common utilities for Medical images segmentation and evaluation.

然后我通过 $ ls/home/jjia/.conda/envs/py37/lib/python3.7/site-packages
进一步检查了它,它显示:
And I checked it futher by $ ls /home/jjia/.conda/envs/py37/lib/python3.7/site-packages
, it shows:
... # other packages
jjnsegutils-0.0.10.dist-info
... # other packages
我认为应该有一个名为 jjnsegutils
的笔记本目录以及 jjnsegutils-0.0.10.dist-info
.但是我没有看到.这是我无法导入自己的软件包的原因吗?
I thought there should be anotehr directory named jjnsegutils
along with jjnsegutils-0.0.10.dist-info
. But I did not see it. Is this the reason that I can not import my own package?
在整个过程中,我确保虚拟环境始终是一个名为 py37
的虚拟环境.我使用的是CentOS,python3.7.
I make sure that the virtual environment is always the same one named py37
during the whole procedure. I used CentOS, python3.7.
期待任何讨论和建议.非常感谢!
Looking forward to any discussion and advice. Thanks very much!
推荐答案
您应 import myutil
.
packages是应该包含在分发程序包中的所有Python导入程序包的列表.无需手动列出每个程序包,我们可以使用find_packages()自动发现所有程序包和子程序包.在这种情况下,软件包列表将为example_pkg,因为这是唯一的软件包. https://packaging.python.org/tutorials/packaging-projects/
