Windows trac-admin initenv fails (no such file or directory / File exists)

[ivan.boscolo]

On my windows system (w2k) everything always worked fine with my svn install (1.3.1) and trac 0.9.5 ..today i only created a new repo and a new environment and worked fine and then deleted them via file system cancel, i succesfully recreated the repository but i cannot create any environment.

Case 1: if i do not create the directory structure and call initenv that's the situation

Trac [C:\TRACProjects\Antalis\Mobis]> initenv
Creating a new Trac environment at C:\TRACProjects\Antalis\Mobis

Trac will first ask a few questions about your environment
in order to initalize and prepare the project database.

 Please enter the name of your project.
 This name will be used in page titles and descriptions.

Project Name [My Project]> Mobis

 Please specify the connection string for the database to use.
 By default, a local SQLite database is created in the environment
 directory. It is also possible to use an already existing
 PostgreSQL database (check the Trac documentation for the exact
 connection string syntax).

Database connection string [sqlite:db/trac.db]>

 Please specify the absolute path to the project Subversion repository.
 Repository must be local, and trac-admin requires read+write
 permission to initialize the Trac database.

Path to repository [/var/svn/test]> C:\SVNRepos\AntalisMobis

 Please enter location of Trac page templates.
 Default is the location of the site-wide templates installed with Trac.

Well, in case 1, I suspect that the parent directory C:\TRACProjects\Antalis didn't exist, and in case 2, the directory C:\TRACProjects\Gts\Sfa already existed.

What you need to do is:

trac-admin x/y/z initenv ...

where x/y exists but z doesn't.

0.10 is a bit more tolerant about this, you can initenv an existing empty folder.

If with those advices are enough to solve your problem, please don't forget to close this ticket as worksforme. already exists but is empty.

Thanks man! Your advices works ;)

I am getting the same error I am trying:

You made the common mistake to confuse a Trac environment directory with the Source Code Repository directory. They can't be the same.

Please (re)read TracEnvironment.
