问题 I'm trying to run CasperJS in a portable way that doesn't involve setting the path variable in Windows. Currently I have gotten this to partially work by moving the phantomjs executable along with the entire contents of the CasperJS directory to the batchbin folder.

When trying to run CasperJS I´m getting the following message: "CasperJS needs PhantomJS v1.x /usr/local/Cellar/casperjs/1.1-beta3/libexec/bin/bootstrap.js:91 in __die" How can I make it run?
