我在RoR上發現了一些新問題，以便發現錯誤。在railstutorial.org之後，我把這個推向了heroku。Heroku - 預編譯資產失敗。推送被拒絕，未能編譯Ruby應用程序
是否因此而中止 - > NoMethodError：未定義的方法`link_to'。
?? 這是我能夠發現的唯一一件事。
warning: push.default is unset; its implicit value is changing in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the current behavior after the default changes, use:
git config --global push.default matching
To squelch this message and adopt the new behavior now, use:
git config --global push.default simple
See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

爲什麼你的'assets/stylesheets'目錄中有'_footer.erb.html'？ –
好問題，那麼在那裏做？我刪除了它.. – Clam
現在讓git commit並嘗試再次將其推送到Heroku。 –
