how to trouble shoot svb2git

[cjohnshu]

I use ruby svn2git.
I have the following error

F:\PRJ\dba>svn2git svn://localhost/ --prefix=svn/ --trunk / --nobranches --notags --authors dba_authors.txt
D:/Ruby32-x64/lib/ruby/gems/3.2.0/gems/svn2git-2.4.0/lib/svn2git/migration.rb:58:in parse': undefined method exists?' for File:Class (NoMethodError)

  if File.exists?(File.expand_path(DEFAULT_AUTHORS_FILE))
         ^^^^^^^^

Did you mean? exist?

This version of svn2git should ignore method `exists?' but the migration.rb in this build still reference to it.
Line 58 of migration.rb
#if File.exists?(File.expand_path(DEFAULT_AUTHORS_FILE))

options[:authors] = DEFAULT_AUTHORS_FILE

#end

Same issue here, installed via gem. Looks like ruby removed the plural method exists in version 3.2.0, should use the singular File.exist? instead.

Thanks for that, I ended up downloading Ruby 3.1.4-1 and was able to continue without any issues.

Work Around for v2.4.0

Open migration.db as admin in your favorite text editor, preferably with line numbering,
I'm on Manjaro Linux, so for me the path was different,
your error should tell you which file though.

For me on Linux it was under:
/usr/lib/ruby/gems/3.2.0/gems/svn2git-2.4.0/lib/svn2git/migration.rb
For @cjohnshu on Windows I can see it's under:
D:/Ruby32-x64/lib/ruby/gems/3.2.0/gems/svn2git-2.4.0/lib/svn2git/migration.rb

Then alter line 58 as following:

- if File.exists?(File.expand_path(DEFAULT_AUTHORS_FILE))
+ if File.exist?(File.expand_path(DEFAULT_AUTHORS_FILE))

Save and exit, svn2git should work as expected now, no Ruby downgrade required! 🎉
