I just ran "dtrace" on "ruby dbcheck.rb" (sqlite test case I
mentioned earlier)
and I see:
0 18561 open:entry ruby /Library/Ruby/Site/
1.8/universal-darwin10.0/sqlite3/sqlite3_native.bundle
Which is the sqlite3 bundle that comes "with" Ruby, rather then the
bundle that
comes with sqlite3-ruby gem. Doing "nm" on the native library bundle
in /Library/Ruby/Site
shows all the expected exported symbols.
So there appears to be two versions of sqlite3. Confirmed:
$ gem list -d sqlite3
Installed at (1.3.2): /Library/Ruby/Gems/1.8
(1.2.4): /System/Library/Frameworks/Ruby.framework/
Versions/1.8/usr/lib/ruby/gems/1.8
Now trying to uninstall the gem version, as Omar Latief suggests
which I hesitated to do before because it said "taps" depends on it:
# gem uninstall sqlite3-ruby
You have requested to uninstall the gem:
sqlite3-ruby-1.3.2
taps-0.3.14 depends on [sqlite3-ruby (~> 1.2)]
Continue with Uninstall? [Yn] Y
Successfully uninstalled sqlite3-ruby-1.3.2
After finishing that, I can run "taps" and not get any errors.
However, when I run "heroku push:db", I see:
Sending data
0 tables, 0 records
Resetting sequences
In other words, no error messages, but it didn't work either,
because my app definitely has data, runs locally and uses sqlite3.
0 tables, 0 records
Resetting sequences
