rails 4.2.0：無法在ubuntu上安裝pg gem 14.04

我最近試圖將我的rail 3.2 *應用程序升級到rails 4.2。*。但是，我在安裝'pg'寶石時停下了腳步。當我使用Google時，這些解決方案只與OSX有關。但我使用的是Ubuntu 14.04。需要對以下問題提出任何建議。rails 4.2.0：無法在ubuntu上安裝pg gem 14.04

我在我的機器上安裝了postgresql 9.3.5版本。

你需要的PostgreSQL

的頭

sudo apt-get install libpq-dev

安裝PostgreSQL的開發包你也可以嘗試

sudo apt-get install postgresql-client 
sudo apt-get install postgresql postgresql-contrib

我已經安裝了這些依賴包。但是，我又失敗了。 – 2015-02-06 11:11:28

你看起來在那http://stackoverflow.com/questions/3116015/how-to-install-gem-pg-on-ubuntu – 2015-02-06 11:13:48

sudo apt-get install postgresql postgresql-contrib，這可能適合你 – 2015-02-06 11:21:15

陶然成在Ubuntu 14.04試圖gem install pg -v 0.18.1在PostgreSQL 9.4這個確切的問題

sudo apt-get install libpq-dev build-essential postgresql-server-dev-9.4

基本上我是缺少postgresql-server-dev-${version}

在你的情況下，嘗試

sudo apt-get install libpq-dev build-essential postgresql-server-dev-9.3

謝謝！順便說一句，sudo apt-get安裝libpq-dev就足夠了。 – mondayguy 2015-05-09 17:46:03

我一直在摔跤這幾天，沒有什麼幫助，直到'build-essential'軟件包安裝好了（對於gem pg 0.21）..我沒有看到其他任何地方，所以謝謝！ – kevlarr 2017-09-04 17:59:32

儘管剛試過用apt-get install libpq-dev gcc make而不是完整的build-essential， – kevlarr 2017-09-04 18:34:08

按照在Ubuntu這個命令16.04

sudo apt install libpq-dev postgresql-server 
sudo -u postgres createuser -s $(whoami); createdb $(whoami) 
gem install pg
