heroku buildpacks的顺序重要吗？

Question

I added several buildpacks in my heroku app :

➜  tennis-match git:(master) heroku buildpacks --app we-tennis-staging                                                                    
=== we-tennis-staging Buildpack URLs
1. https://github.com/heroku/heroku-buildpack-ruby
2. http://github.com/stomita/heroku-buildpack-phantomjs.git
3. https://github.com/ddollar/heroku-buildpack-multi.git
4. https://github.com/heroku/heroku-buildpack-nodejs.git
5. --buildpack=https://github.com/ddollar/heroku-buildpack-multi.git

but now I cannot push anymore to heroku :

-> Fetching custom git buildpack... done
remote: -----> PhantomJS app detected
remote: -----> Fetching PhantomJS 1.9.8 binaries at https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.8-linux-x86_64.tar.bz2
remote: -----> Extracting PhantomJS 1.9.8 binaries to /tmp/build_d85248ffdc50138a22fb863a0367b5f2/vendor/phantomjs
remote: -----> exporting PATH and LIBRARY_PATH
remote: -----> Fetching custom git buildpack... done
remote: 
remote:  !     Push rejected, failed to detect
remote: 
remote: Verifying deploy...
remote: 
remote: !   Push rejected to we-tennis-staging.

Does the order of the buildpacks has any importance. Why is my app crashing ?

当您尚未设置Buildpack的所有依赖项时，就会发生这种情况-有些buildpacks要求您在应用程序中进行特定设置
