Getting "no such file or directory" - transpec_analysis_result.json

[myronmarston]

Running transpec against rspec-mocks spec suite, I get this:

I guess your rspec-mocks directory is in rspec-dev/repos. In that case, the Gemfile of rspec-mocks refers ../rspec-core and ../rspec-expectations. However, as described in the README, Transpec needs to run the specs in a temporarily copied project directory, but the parent directory won't be copied. So I think you need to run transpec --rspec-command 'bundle install && bundle exec rspec'

[yujinakayama]

I've confirmed transpec --rspec-command 'bundle install && bundle exec rspec' is working, and fixed some issues in Transpec with rspec-mocks project (including #46). Please try out version 1.9.3.

@myronmarston Can I close this issue?

[myronmarston]

Yep!

[myronmarston]

Hmm, actually, one suggestion: it seems like transpec can determine if a project will have this issue by looking at Gemfile.lock and/or Gemfile and seeing it has some :path gems that are outside the working directory, and that therefore will have this issue. Rather than failing with this confusing error, could it give a better error message instructing the user to use a different --rspec-command option?

[yujinakayama]

I think there would be various problems with project-specific setup, and handling only this case does not help much. However I agree the error No such file or directory - transpec_analysis_result.json (Errno::ENOENT) does not give enough information for troubleshooting and it should be improved.
