[英]Why does my rails app not deploy (H10 code error) and rails server not start?
我只是用一個“ hello world”頁面和基本框架的Rails應用程序的開始。 我開始嘗試將其部署到heroku之前。 但是,在生產服務器和本地服務器上,我都無法啟動該應用程序。 我確實曾經在本地主機3000上啟動過一次,但是現在我做了一些更改,但它不起作用。 我唯一改變的就是將sqlite寶石投入開發,並將pg寶石投入生產,因為herku無法與sqlite配合使用。 請查看以下錯誤:
嘗試啟動本地服務器時:

在生產環境中打開eapp時出現H10錯誤,不幸的是,herko支持頁面並未詳細介紹如何解決此錯誤,只是指出了代碼含義,我不理解。

這是使用postgresql的正確配置嗎?
請參閱默認情況下如何將sqlite3
指定為適配器?
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
然后,在生產環境中,使用默認值並指定sqlite3
數據庫。
production:
<<: *default
database: db/production.sqlite3
相反,它應該類似於:
production:
<<: *default
adapter: postgresql
encoding: unicode
同樣,您確實應該在開發機器上設置postgresql,以避免sqlite3和postgresql之間的語法差異。
要配置數據庫,請在Heroku上轉到應用程序的“資源”選項卡。 在“附加組件”下,搜索“ Postgres”。 Heroku將引導您從那里通過。
設置完成后,您需要在終端中運行:
> heroku run rake db:migrate --app your_app_name
或者,如果您希望從架構中加載(這基本上是將所有遷移混入一個文件中的結果),則可以執行以下操作:
> heroku run rake db:schema:load
回復
這是我的一個應用程序的database.yml
樣子(自然,我用'app_name'代替了我的實際應用程序名稱):
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: 5
...
production:
<<: *default
database: app_name_production
username: app_name_admin
password: <%= ENV['APP_NAME_DATABASE_PASSWORD'] %>
如您所見,實際上我的生產部分中有database:
和username:
。 username:
可能不是必需的,我不確定。 根據Heroku上的SQLite ,您應該包括database: ...
但是,如指南中所述,它應該是一個自定義名稱,而不是:
database: db/production.sqlite3
encoding
和pool
位來自《 Rails指南》中有關配置數據庫的第3.15.3節(配置PostreSQL數據庫)。 您會注意到,Heroku指南沒有指定encoding
但是Rails指南卻指定了encoding
。 我將Rails指南優先於Heroku指南,因此將其包含在我的所有database.yml
文件中。
您已經在我們的default
包含了pool
和timeout
,因此您無需在production
重新配置它們。
“在開發計算機上設置postgreSQL”是指在本地計算機上安裝postgreSQL服務器。 僅包含pg
gem並不會安裝服務器。 你只需要做到這一點,如果你決定在發展中使用PostgreSQL(而不是源碼)。 這與部署到Heroku 無關 。
要了解有關在計算機上安裝postgresql的更多信息,請參見Heroku Postgres指南的Local setup部分。
您可能還需要閱讀“ 十二要素應用程序”的“ 開發/產品奇偶校驗”部分。
如果您決定繼續使用sqlite進行開發並使用postgresql進行部署,則可以完全忽略我有關在開發計算機上設置postgresql的評論。 但是,正如我之前說過的,sqlite和postgres在語法上有一些細微的區別(我記得最主要的是每個數據庫如何實現LIKE
功能)。 這意味着您可能擁有在sqlite上的開發中可以完美運行但在postgres上的生產中斷的代碼。 如果遇到這種情況,您將不得不找出語法差異導致錯誤的位置,然后對語法進行補救。 那是沒有樂趣的。
您的本地服務器錯誤是由於文件引起的
from C:/Sites/nutri/config/application.rb:7:in '<top (required)>'
錯誤是
C:/RailsInstaller/Ruby2.2.0/lib/ruby/gems/2.2.0/gems/sqlite3-1.3.5-x86-
mingw32/lib/sqlite3.rb:6:in 'require': cannot load such file --
sqlite3/sqlite3_native (LoadError)
檢查文件sqlite3/sqlite3_native
存在。
首先嘗試在本地部署並考慮一下Heroku。

說rails
(ActiveRecord)和sqlite3
之間的寶石兼容性問題。 您有任何理由對sqlite3
的版本發表評論嗎? 嘗試取消注釋
gem 'sqlite3', '1.3.5'
只有某些版本的rails
可以與sqlite3
版本一起使用
另外, pg
gem可以有如下版本嗎
gem 'pg', '0.18.4'
嘗試所有這些,移動您的Gemfile.lock

mv Gemfile.lock Gemfile.lock_
