I followed the instructions on the instiki site to create and host a wiki on heroku. But there seems to be an error which is probably to do with the gemfile? Here is the build log

Could someone help with this issue?

Hmm. Yes, it looks like the Gemfile.lock.heroku was out-of-sync with the Gemfile.heroku. I’ve updated both of them.

I tried it again and got this error:

I am not sure now if this was a problem from my side.

Clearly you are trying to use the wrong Gemfile.lock. The correct one (which you are supposed to rename from Gemfile.lock.heroku) doesn’t have a “BUNDLED WITH” line in it.

Try following these instructions.

I followed the exact instructions on the site. The Gemfile.lock that I can see on my machine also doesn’t have the “BUNDLED WITH” line. The code seems to be running BUNDLED_WITHOUT :

remote: Running: BUNDLE_WITHOUT=‘development:test’ BUNDLE_PATH=vendor/bundle BUNDLE_BIN=vendor/bundle/bin BUNDLE_DEPLOYMENT=1 BUNDLE_GLOBAL_PATH_APPENDS_RUBY_SCOPE=1 bundle install -j4

But I do not know what BUNDLED_WITH version it is removing in a previous line. None of the files (Gemfile or Gemfile.lock) seem to have either BUNDLED_WITH or the BUNDLED_WITHOUT line. I found a dicussion on stackoverflow but the accepted answer says the same thing the log file says. I did not run bundle install at any point.

Hmm. Looking more closely at your error message, I think this commit might fix your problem. Dunno what the source of the extra space is, but that seems to be the cause of Heroku’s complaints.

It works now! Thanks!
