简短摘要
我可以将一个包上传到pyPI,然后用pip安装它,但是当我尝试导入它时,Python没有看到它(它说没有相关名称的模块)。我在Windows 7中使用Python 2.7(Anaconda发行版,使用iPython解释器)。
详细摘要
我正在学习如何在奶酪店(pyPI)上传包(mymathFoo),并尝试确保我可以在上传后安装它。当我手动将包文件夹粘贴到我的Lib / site-packages目录中时,它会从我的解释器导入并正常工作。
我做了什么:
0。写包
这是一个带有加法和减法模块的愚蠢小包(例如,添加(1,2))。该目录的结构如下:
\mymathFoo
__init__.py
add.py #adds two numbers
subtract.py #subtract two numbers
setup.py #shown below
README.txt #simple description of package
__init__.py文件如下:
from add import add
from subtract import subtract
1。在pyPI注册包
即,从命令行输入:
python setup.py register
返回:
running register
running check
Registering mymathFoo to http://pypi.python.org/pypi
Server response (200): OK
注意我的setup.py文件是:
from distutils.core import setup
setup(name="mymathFoo",
version="0.6.2",
url="http://mymathfoo.net",
maintainer='Math Foo',
maintainer_email='mathfoo@math.org',
py_modules=['add','subtract'],
description="Silly little math turd to add/subtract.")
请注意,如果我将其更改为py_modules='mymathFoo'
,我会收到与以下相同的错误。
2。上传包 在命令行中,我输入了:
python setup.py sdist bdist_wininst upload
答案是:
running sdist
running check
warning: sdist: manifest template 'MANIFEST.in' does not exist (using default fi
le list)

running upload

似乎已经了。到现在为止还挺好。
第3。使用pip在本地安装此软件包。
然后我在命令行中使用pip安装此软件包:
pip install mymathFoo
我得到了:
Downloading/unpacking mymathFoo
Downloading mymathFoo-0.6.3.zip
Running setup.py (path:c:\users\eric\appdata\local\temp\pip_build_Eric\mymathF
oo\setup.py) egg_info for package mymathFoo
Installing collected packages: mymathFoo
Running setup.py install for mymathFoo
Successfully installed mymathFoo
Cleaning up...
运行上述操作会将以下目录复制到我的Lib/site-packages
文件夹中:
mymathFoo-0.6.3-py2.7.egg-信息
4。导入包(不是)
这是我遇到问题的地方。我打开我的iPython解释器(使用Anaconda分发的Python,Windows 7):
import mymathFoo
我明白了:
Traceback (most recent call last):
File "<ipython-input-7-b7486b6a0225>", line 1, in <module>
import mymathFoo
ImportError: No module named mymathFoo
我错过了什么?为什么我可怜的小模块看不见?
更新
请注意,如果我将所有文件都折叠到根目录(我最终不想这样做),那么错误就会消失。不幸的是,我经常会在我的根目录中找到目录,而我根据注释尝试的任何内容都修复了这个问题。
我仍在寻找答案,这里的讨论看起来很有希望: http://www.scotttorborg.com/python-packaging/index.html# 我会解决这个问题并发布我发现的任何解决方案。

注意 这是基于Michael Driscoll撰写的Python 101一书所做的一些工作(目前处于草稿形式)。
答案 0 :(得分:3)
您的软件包确实安装了,而不是按照您的意图安装:
$ pip install mymathFoo
Downloading/unpacking mymathFoo
Using download cache from /Users/stu/tmp/pip-cache/http%3A%2F%2Fpypi.counsyl.com%2Froot%2Fpypi%2F%2Bf%2F64ef17a9135f05820c2d96050ce4315d%2FmymathFoo-0.6.3.zip
Running setup.py egg_info for package mymathFoo
Installing collected packages: mymathFoo
Running setup.py install for mymathFoo
Successfully installed mymathFoo
Cleaning up...
$ python
Type "help", "copyright", "credits" or "license" for more information.
>>> import add
>>> import subtract
>>>
你的setup.py说要安装两个模块,“添加”和“减去”,而不是安装名为mymathFoo的软件包。将add.py和subtract.py放在名为'mymathFoo'的文件夹中,并在setup.py中设置py_modules = ['mymathFoo']。
最后,您可以测试您的包装而不会碰到pypi。只需运行python setup.py install
,然后尝试导入您的包。
答案 1 :(得分:2)
它对我有用:
>>> import mymathFoo
>>> dir(mymathFoo)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']
虽然您的模块没有输出任何内容。从@ Stu-Gla的答案开始,您似乎更改了自己的软件包,因为您从源代码中删除了add.py
和subtract.py
。
顺便说一下,你不需要为pypi注册一个虚拟包来测试它,你也可以使用pip在本地安装一个包:
pip install /path/to/sources # path where the setup.py is
