Unable to run clean task

[just-boris]

When I have made some changes in the configuration, the tool said me the following

Remote url mismatch.  Got "<something>" but expected "<something-else>" in node_modules/gh-pages/.cache. 
If you have changed your "repo" option, try running the "clean" task first.

I have tried to run gh-pages clean, but it didn't succeed. What kind of task should I run to clean the cache?

[kevincolten]

you can run rm -rf node_modules/gh-pages/.cache to clean the cache manually

Actually, there is a clean function exported from the code.

I wanted to do the same operation via CLI. If it is not possible now, I will be happy to send a PR. How about command?

gh-pages --clean

@just-boris that function is in the lib, not in the cli.

@tschaub this tripped me up just now as well, but @kevincolten 's solution works well. I think it might be enough to just change the error message to:

Remote url mismatch.  Got "<something>" but expected "<something-else>" in node_modules/gh-pages/.cache. 
If you have changed your "repo" option, try clearing the cache by running:
  rm -rf node_modules/gh-pages/.cache

Let me know if you want me to open a pr with that change.

Since I was using nvm I had to run

rm -rf ~/.nvm/versions/node/v7.6.0/lib/node_modules/gh-pages/.cache

With the changes in #173, these cache collisions shouldn't be a problem any more. In addition, the package will now make a gh-pages-clean script available so people can remove all cached clones.
