Cryptic error when trying to run POW

问题

I am having a rather weird error message when running POW for my rails app.

I followed the instructions:

- cd ~/.pow
- ln -s /Users/mingyeow/Dailymuses-Server-Side

And got this:

Error starting application
Your Rack app raised an exception when Pow tried to run it.

Tried resetting everything I could find.

I've had the exact same error today with an Octopress install.

Does your .powrc look like the following?

if [ -f "$rvm_path/scripts/rvm" ] && [ -f ".rvmrc" ] ; then
   source "$rvm_path/scripts/rvm"
   source ".rvmrc"
fi

That's the one provided with Octopress, but I guess it's pretty generic.

In my case, I had modified the .rvmrc file and it contained a syntax error. I corrected the error, deleted the symlink in ~/.pow and created it again, and all went back to normal.

Hope that helps!
(if not, maybe you should update your question with the content of your .powrc file)
