Re: [Tutor] RuntimeError: file does not exist
Hi Alan!! After I read your e-mail, I remebered that I run the scripts in a different way. The script worked properly when I run it from Python IDLE, I don't have any idea the reason why. 2011/5/19 Alan Gauld > > "Susana Iraiis Delgado Rodriguez" wrote > > > Well, I tried this code in other computer and it worked just fine. >> > > >> But when I run the module in my computer it throws many errors, >> > > So what is different between the computers? > What are the respective OS versions and Python versions? > > How exactly are you running the code on each > computer - double click in exporer, from IDLE, from the command line? > > Its hard to tell what the problem is from your description. > > > lyr.datasource = mapnik.Shapefile(base=ruta,file=archivo[0]), it shows >> Python Runtime Error: wrong file code: -1991225785 >> > > But that looks odd, possibly a problem with the python script file itself? > > > -- > Alan Gauld > Author of the Learn to Program web site > http://www.alan-g.me.uk/ > > > > > ___ > Tutor maillist - Tutor@python.org > To unsubscribe or change subscription options: > http://mail.python.org/mailman/listinfo/tutor > ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] RuntimeError: file does not exist
"Susana Iraiis Delgado Rodriguez" wrote Well, I tried this code in other computer and it worked just fine. But when I run the module in my computer it throws many errors, So what is different between the computers? What are the respective OS versions and Python versions? How exactly are you running the code on each computer - double click in exporer, from IDLE, from the command line? Its hard to tell what the problem is from your description. lyr.datasource = mapnik.Shapefile(base=ruta,file=archivo[0]), it shows Python Runtime Error: wrong file code: -1991225785 But that looks odd, possibly a problem with the python script file itself? -- Alan Gauld Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] RuntimeError: file does not exist
Hello everyone! Well, I tried this code in other computer and it worked just fine. I changed the line: lyr.datasource = mapnik.Shapefile(base=filepath, file=filepath) for lyr.datasource = mapnik.Shapefile(base=ruta,file=archivo[0]) I also did hard coding to test my script: lyr.datasource = mapnik.Shapefile(file='C:\\Python26\\tapalpa_05_plani_line') It also worked as well!! But when I run the module in my computer it throws many errors, if I use lyr.datasource = mapnik.Shapefile(base=ruta,file=archivo[0]), it shows Python Runtime Error: wrong file code: -1991225785 2011/5/19 Brad Posthumus > > > > Susana Iraiis Delgado Rodriguez wrote: > > > > Hello Alan!! > > Can you please tell me, how to rebuild my path?
