The ESRI ArcGIS software uses Python scripts. You can specify in an options dialog what executable to use for script editing and debugging. In presentations from ESRI, I have seen them use Wing IDE in this way for editing scripts.
I put in the path to PyCharm for my script editor and debugger, but when I try to edit a script, I get the following error from PyCharm:
Error Loading Default Project
Extension is missing for storage file: C:\Program Files\ArcGIS\Desktop10.0\ArcToolbox\Scripts
That path shown in the error is the directory where the script I was trying to edit resides.
What does this error mean and how can I fix it?
