Eclipse+PyDev+GAE memcache error

Answer 1

What version of PyDev are you using? A recent one (1.5) or the old one referred by the Google tutorial?
See this thread.

There is a similar issue with PyROOT

Since PyDEV plugin does not read $HOME/.pystartup, touching functions/ classes is not a solution. Because it analyze the syntax and structures of python modules to be imported not on-the-fly but when I set the PYTHONPATH from Eclipse's preference panel.

So does your PYTHONPATH reference the Google library?

They might be an issue with code completion in 1.5 which could force you to disable code analysis: Pydev 1.5.0 code anlaysis breaks code pyqt4 code completion - ID: 2855598

have pyqt 4.5.4 installed.
Initially I had pydev 1.4.8 the open source version installed and code completion worked fine.
After updating to pydev 1.5.0, pyqt code completion stopped functioning.
After disabling the Pydev code analysis in "eclipse preferences -> pydev -> editor -> code analysis -> do code analysis?", code completion began working again for PyQt classes etc.

Answer 2

I have the same problem,Any one know how to fix that?

Answer 3

Trying VonC's advise for disabling code analysis worked for me.

Answer 4

I'm a bit late to the party, but you can add the following comment in all of your files that use memcache to selectively switch off pydev analysis:

#@PydevCodeAnalysisIgnore

Answer 5

If you don't want to turn off all code analysis for your project/module, then just turn it off for that line. This answer explains that you can hit Ctrl+1 to bring up quick fix and insert #@UndefinedVariable at the end of the line.
