Error installing registration .5 into existing project: "The system cannot find the file specified"

[Mark Thomas]

Hi everyone,

I've been running a turbogears project for some time and just recently
found out about registration. When I attempted to add registration 0.5
to my project, I get the error stated in the subject of this post. The
trace is included below. Interestingly, the last command to execute
("Copying registration.cfg to ../project_foo\project_foo\config
\registration.cfg") appears to complete successfully: the
registration.cfg file does appear in my yourcoolfried\config\
directory and is identical to the file in the registration
distribution.

Any thoughts very much appreciated.

I am running on Windows XP with Python 2.5 and Turbogears 1.0.4.4

Thanks!
Mark

My only thought is to try

tg-admin update -t registration

again. Answer n to everything as before.

If you get the same (or similar) results, we may need to take this to
the paste mailing list, because I'm really not sure what is going on.

Hey Patrick,

First, thanks for your response. I was able to install cleanly by
checking out my code onto a linux box and running the update there.

My hunch is that this is an ugly Windows path-separator ugliness. If
you look at the output above, you'll notice several lines like the
following:
Copying <bar> to ../project_foo\project_foo\registration\<bar>

I suspect that leading forward slash to be the culprit as "cd ../
project_foo\project_foo" fails from a Windows command prompt. Being
unfamiliar with PasteScript and the internals of tg-admin, I'm unsure
of where this might be located in the code.

Hope this helps.
Mark
