I was able to get rid of the import errors executing this cmd

I was lucky, testing different things I could resolve it but I'm not sure why I have to do this and how I could avoid doing it.

I'm on Mac OS X, but all I had to do was to add:

<pre><code>/Library/Python/2.6/site-packages
</code></pre>

to my System PYTHONPATH (Found in: Preferences > Pydev > Interpreter - Python)

The equivalent for Ubuntu 10.04 would be:

<pre><code>/usr/lib/pymodules/python2.6
</code></pre>

I'm guessing that the equivalent for Ubuntu 9.x could be:

<pre><code>/usr/lib/python2.6/site-packages
</code></pre>

If it isn't and you're tired of looking, just upgrade to Ubuntu 10.04 and you should be fine.

"Unresolved imports" occur when Eclipse/Pydev does not know what you want to import. Check your Pydev settings in the Eclipse preferences > Interpreter Python. Your site-packages folder and things you want to import should be there in the Pythonpath.

blocks|key|3040171|text|即使将库/站点包添加到PYTHONPATH中，当使用通过easy_install安装的egg包中的模块时，也可能会发生此问题。这些包的问题是，默认情况下，它们不会直接安装在Lib/site-+package中，而是安装在包含完整包名称并带有.egg后缀的文件夹下。这实际上可能取决于easy_install版本。例如：Lib/site-packages/django_celery-3.0.23-py2.7.egg|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3040172|来自上面安装的包的每个模块都需要在PYTHONPATH中有一个单独的条目。如果软件包是在系统上安装PyDev之后安装的，则需要在PyDev中更新系统PYTHONPATH。这是通过转到窗口->+Preferences+->+PyDev+->在python解释器面板中选择您的解释器->来自动完成的，删除并重新添加您当前的python解释器(通常，这应该是系统中的python可执行文件)。然后，PyDev重启(文件->重启)应该可以解决“未解决的导入”错误。|3040173|entityMap^0|4F|1C|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

Even if Lib/site-packages is added to the PYTHONPATH, this problem may happen when using modules from egg packages installed using easy_install. The problem with those, and that might actually depend on the easy_install version, is that by default they don't get installed directly inside Lib/site-packages but rather under a folder containing the full package name and having the .egg suffix. For example: <code>Lib/site-packages/django_celery-3.0.23-py2.7.egg</code>

Each module coming from packages installed as above needs an individual entry in PYTHONPATH. If the packages are installed after PyDev has been installed on the system, the system PYTHONPATH needs to be updated in PyDev. That is done automatically by going to Window -> Preferences -> PyDev -> Select your intepreter -> in the python interpreters panel remove and re-add your current python interpreter (usually, this should be the python executable from the system). Then a PyDev restart (File -> Restart) should solve the "Unresolved import" errors.

If you are facing problem of unused imports then I must say use Eclipse as a IDE as it is providing functionality to remove unused imports by pressing keys ctr+shift+O. Or In Eclipse there is plugin also available which is doing the same thing automatically when you save your code.You can get that plugin from eclipse plugin site easily and free of cost.

In my case of the modules were dependent on setuptools-14.3.1 , which was causing all these problems. After installation of setuptools-14.3.1 rest of the modules automatically resolved.

I was having a single import error when working in PyDEV in eclipse. 

I was importing it like

<pre><code>from xyz_module import abc
</code></pre>

So I clicked "Ctl + 1" and "select Unresolved import error" in eclipse and it created a class 
file in a python file. 

It turned out that I had created an application called "xyz_module" and a "xyz_module.py" file (with the same name that is) and this was causing an import error. I changed the python file to a new name and this resolved the error.

I had the same error and none of the answers worked for me as there was no PYTHONPATH options under Window -> Preferences -> PyDev -> Python.

Instead I added PYTHONPATH setting in the menu:

<blockquote>
 Project -> PyDev-PYTHONPATH -> External Libraries -> Add Source folder
</blockquote>

I added the path of site-packages like

<blockquote>
 /home/Documents/hcx/venv/lib/python3.5/site-packages
</blockquote>

Now PyDev stopped complaining.

I'm doing my VERY first project using python/django/eclipse/pydev following this guide

<a href="http://docs.djangoproject.com/en/dev/intro/tutorial01/" rel="nofollow noreferrer">http://docs.djangoproject.com/en/dev/intro/tutorial01/</a>

My only addition is the use of Eclipse/pydev.

I'm getting many errors related to "Unresolved imports". I can remove the errors using "remove error markers" and my site runs perfect (I can browse it) but I want to get rid definitively of this problem since errors pop up again after I removed them.

Any ideas? 

EDIT

Using Ubuntu 9.1

Unresolved import: models

我正在使用python/django/eclipse/pydev完成我的第一个项目，遵循本指南我唯一的补充是使用了Eclipse/pydev。我收到了许多与“未解决的导入”相关的错误。我可以使用“删除错误标记”来删除错误，我的网站运行得很好(我可以浏览它)，但我想彻底摆脱这个问题，因为在我删除它们之后，错误再次出现。有什么想法吗？编辑使用Ubuntu 9.1
