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)

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。

how to install package with pypi in python 2.7?

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)。

2 个答案:

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.pysubtract.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
