heroku buildpacks的順序重要嗎？

Question

我在heroku應用程序中添加了幾個buildpack：

➜  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

但是現在我不能再推到heroku了：

-> 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.

buildpack的順序是否重要？ 為什么我的應用程序崩潰了？

當您尚未設置Buildpack的所有依賴項時，就會發生這種情況-有些buildpacks要求您在應用程序中進行特定設置
