It is possible you just need to re-configure your python path within Eclipse. See my <a href="https://stackoverflow.com/questions/2143549/undefined-variable-from-import-when-using-wxpython-in-pydev/3743861#3743861">answer</a> to a similar question.

blocks|key|1352097|text|我也有同样的问题。我在Windows上使用Python和Eclipse。代码运行得很好，但是eclipse到处都显示错误。在我将文件夹'Lib‘的名称更改为'lib’(C:\Python27\lib)之后，这个问题就解决了。看起来，如果字母的大小写与配置文件中的不匹配，这有时会导致问题(但似乎并不总是如此，因为错误检查在问题突然出现之前很长一段时间都是正常的)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1352098|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had the same problem. I am using Python and Eclipse on Windows. The code was running just fine, but eclipse show errors everywhere. After I changed the name of the folder 'Lib' to 'lib' (C:\Python27\lib), the problem was solved. It seems that if the capitalization of the letters doesn't match the one in the configuration file, this will sometimes cause problems (but it seems like not always, because the error checking was fine for long time before the problems suddenly appeared for no obvious reason).

I'm using opencv which relies on binaries etc so I have scripts where every other line has this silly error. Python is a dynamic language so such occasions shouldn't be considered errors.

I removed these errors altogether by going to:

Window -> Preferences -> PyDev -> Editor -> Code Analysis -> Undefined -> Undefined Variable From Import -> Ignore

And that's that.

It may also be, 
Window -> Preferences -> PyDev -> Editor -> Code Analysis -> Imports -> Import not found -> Ignore

I was having a similar problem with an Eclipse/PyDev project. In this project the root directory of the python code was a sub-directory of the project.

<pre><code>--&gt; MyProject
 + --&gt; src Root of python code
 + --&gt; module1 A module 
 + --&gt; module2 Another module
 + --&gt; docs
 + --&gt; test
</code></pre>

When the project was debugged or run everything was fine as the working directory was set to the correct place. However the PyDev code analysis was failing to find any imports from module1 or module2.

Solution was to edit the project properties -> PyDev - PYTHONPATH section and remove /MyProject from the source folders tab and add /MyProject/src to it instead.

This worked for me:

step 1) Removing the interpreter, auto configuring it again

step 2) Window - Preferences - PyDev - Interpreters - Python Interpreter
 Go to the Forced builtins tab
 Click on New...
 Type the name of the module (curses in my case) and click OK

step 3) Right click in the project explorer on whichever module is giving errors. Go to PyDev->Code analysis.

If you're sure that your script runs and that it is a false alarm, Go to Preferences > PyDev > Editor > Code Analysis. Demote the errors to warnings.

I've got a Python project using PyDev in Eclipse, and PyDev keeps generating false errors for my code. I have a module <code>settings</code> that defines a <code>settings</code> object. I import that in module <code>b</code> and assign an attribute with:

<pre><code>from settings import settings
settings.main = object()
</code></pre>

In some of my code--but not all of it, statements like:

<pre><code>from settings import settings
print settings.main 
</code></pre>

... generate "Undefined variable from import: main" messages in the Eclipse code error pane, even though the code runs without a problem. How can I correct these?

How do I fix PyDev "Undefined variable from import" errors?
