rake db：用postgresql創建編碼錯誤

我正在導入一個現有的rails項目，這是我正在使用的新的arch linux系統，我已經正確安裝了所有的gem和postgresql，但運行時遇到一些問題：rake db：用postgresql創建編碼錯誤

rake db:create

我收到以下錯誤

PGError: ERROR: new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII) 
HINT: Use the same encoding as in the template database, or use template0 as template. 
: CREATE DATABASE "System_test" ENCODING = 'unicode'

我用正確的編碼手動創建數據庫和遷移效果不錯，但我可以運行

rake db:test:clone

命令，因爲它試圖創建一個數據庫，我不假設手動創建數據庫。那麼，有人知道要解決這個問題？

問候

編輯：這是我的database.yml

development: 
    adapter: postgresql 
    encoding: unicode 
    database: System_development 
    pool: 5 
    username: forellana 
    password: 

test: &test 
    adapter: postgresql 
    encoding: unicode 
    database: System_test 
    pool: 5 
    username: forellana 
    password: 

cucumber: 
    <<: *test

和這裏的命令

什麼是你的database.yml文件是什麼樣子？ – 2011-04-28 15:50:55

你是如何在你的系統上安裝postgresql的？來源還是包裝？ 'psql --command =「\ l」'的輸出是什麼樣的？ – 2011-04-28 16:09:19

的完整輸出這裏的主要問題是，你的模板數據庫（template1）已經使用ASCII編碼創建，並告訴PostgreSQL使用UTF8編碼創建新的數據庫。不用說，這並不令人感到特別高興。你可以做的是擦除你的template1數據庫，並使用these instructions重新創建它。當您的主機提供商沒有正確設置區域設置時，這也可能是一個問題。你可以閱讀關於fixing your missing locales的更多信息。

我發現所有這些信息通過這篇文章瞭解Fixing PostgreSQL's default encoding on Ubuntu 9.10

謝謝，我沒有命令pg_dropcluster o我不知道在哪裏調用它們，但是在那篇文章的第一條評論中，我找到了正確的解決方案。 – fespinozacast 2011-04-28 16:31:44

非常好，我很高興你找到了適合你的解決方案。 – 2011-04-28 18:52:23

只是一個提示，如果你正在初始化數據庫：'initdb -E UTF8' – l0b0 2012-11-19 12:03:24

要在Rails的解決這個問題，我發現，您可以在下面一行簡單地添加到每個部分（開發/生產等），您database.yml的文件：

template: template0

請參閱ActiveRecord/ConnectionAdapters/PostgreSQL/SchemaStatements#create_database其他選項。

可以更改Postgres的模板1通過做是UTF下面張貼here:

UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1'; 
DROP DATABASE template1; 
CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE'; 
UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1'; 
\c template1 
VACUUM FREEZE; 
UPDATE pg_database SET datallowconn = FALSE WHERE datname = 'template1';

OSX，爲我工作，安裝pg with homebrew，版本9.3.2，Rails 4.0.5 – Valentin 2014-06-30 07:17:12

錯誤：編碼「UTF8 「與語言環境不匹配」en_US「細節：選擇的LC_CTYPE設置需要編碼」LATIN1「。 – Uilleann 2017-01-13 16:35:39

到我發現這個要點是非常有幫助的其他答案相似。使用Ubuntu 14.04。我想更改默認模板以使用UTF-8。

進入postgres的提示：

Activate the postgres console. 
su - postgres 
psql

然後鍵入以下命令：

# First, we need to drop template1. Templates can’t be dropped, so we first modify it so t’s an ordinary database: 

     UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1'; 

# Now we can drop it: 

     DROP DATABASE template1; 

# Now its time to create database from template0, with a new default encoding: 

     CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE'; 

# Now modify template1 so it’s actually a template: 

     UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1'; 

# Now switch to template1 and VACUUM FREEZE the template: 

     \c template1 

     VACUUM FREEZE;

謝謝，這很好。 – 2015-02-25 14:42:16

在配置添加

template: template0

/database.yml的工作對我來說:-)
