Heroku問題：NameError（未初始化的常量Cartographer :: Gmap）：

Question

我只是想知道是否有人可以幫助我解決heroku問題（似乎有很多！）...我正在與本地服務器上的制圖師一起工作，並且有一張很棒的小地圖，上面裝有用戶個人資料頁面...但是，由於上述錯誤消息，我似乎無法在Heroku上獲得相同的功能。 我最初使用git clone git://github.com/parolkar/cartographer.git vendor/plugins/cartographer安裝了制圖師，並且在本地服務器上運行良好。.然后我嘗試通過gemfile安裝制圖師gem，然后重新部署，但這並沒有改變錯誤。

有人對此有線索嗎？ 謝謝！

Gem和插件不是同一項目，但是有兩個不同之處：

• 寶石=> https://github.com/erikh/cartographer/
• 插件=> https://github.com/parolkar/cartographer

如果要使用gem，請僅將其添加到Gemfile中

如果要使用插件，則需要通過git-submodule添加它

rm -rf vendor/plugins/cartographer
git submodule add git://github.com/parolkar/cartographer.git vendor/plugins/cartographer
git submodule init
git commit -m 'add cartographer like submodule'
