I'm trying to use eclipse with PyDev to program in python. In Windows 7 x64, I've added a PATH environmental variable (PATH C:\Python26\ArcGIS10.0\python.exe;) and what I thought were the relevant folders to PYTHONPATH (C:\Dropbox\CODE\Python\; C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy)

However, when I type the command: 

import arcpy

in eclipse I get an error message. However, when I try importing ArcPy via IDLE I have no problems. Is there some way that I should be including arcpy in the build path that I am missing?

You need to add %ARCGISINSTALLDIR%\bin and %ARCGISINSALLDIR%\arcpy to your paths as well.

Should I add these to PATH and PYTHONPATH? – djq Nov 4 '10 at 10:33
Nah, the .pth file that gets installed in %PYTHONINSTALL\Lib\site-packages should take care of it for you. – Jason Scheirer Nov 4 '10 at 18:55
So where exactly do I add them? Should I create new environmental variables? Thanks for your help – djq Nov 4 '10 at 19:31
In that same dialog you posted the screen shot of. – Jason Scheirer Nov 4 '10 at 21:21

Great - thank you. (To be clear for future readers, I added C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy and C:\Program Files (x86)\ArcGIS\Desktop10.0\bin) to the Python Interpreter path in eclipse. – djq Nov 4 '10 at 21:54

The same needed configuration, but in ArcGIS 10.1

I have been getting an unresolved error on "TableToNumPyArray" even with the settings you pointed out here, any thoughts on what the issue could be? – GuidoS Nov 27 '12 at 21:30

I never tryed it before, but I have the same issue: <arcpy.da.NumPyArrayToTable(whatever...)> = "Undefined variable from import". It seems like we are missing some other path or having an import problem... I'll try to find it. – Víctor Velarde Nov 29 '12 at 15:19
