[英]How to Install Postgresql Gem on Ubuntu
I have Ubuntu 12.04 Precise installed via crouton on my Asus Chromebook. 我在华硕Chromebook上通过crouton安装了Ubuntu 12.04 Precise。 I have a rails application that requires postgres.
我有一个需要postgres的rails应用程序。 When I run "bundle" it fails to install the pg gem.
当我运行“bundle”时,它无法安装pg gem。 I try installing multiple versions of it independently and it fails.
我尝试独立安装它的多个版本,但它失败了。 The failure report is below:
失败报告如下:
Building native extensions.
构建原生扩展。 This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension.
这可能需要一段时间...错误:安装pg时出错:错误:无法构建gem原生扩展。

检查mkmf.log文件以获取更多详细信息。 You may need configuration options.
您可能需要配置选项。

extconf失败,退出代码1
Gem files will remain installed in /home/oscar/.rvm/gems/ruby-1.9.3-p551/gems/pg-0.18.1 for inspection.
Gem文件将保留在/home/oscar/.rvm/gems/ruby-1.9.3-p551/gems/pg-0.18.1中进行检查。 Results logged to /home/oscar/.rvm/gems/ruby-1.9.3-p551/extensions/x86_64-linux/1.9.1/pg-0.18.1/gem_make.out
结果记录到/home/oscar/.rvm/gems/ruby-1.9.3-p551/extensions/x86_64-linux/1.9.1/pg-0.18.1/gem_make.out
I also tried to install it using brew. 我也尝试使用brew安装它。 The files downloaded, and seem to install but when I run "brew upgrade postgresql" it says that postgresql doesn't exits.
下载的文件,似乎安装,但当我运行“brew upgrade postgresql”时,它说postgresql不会退出。 I am all out of ideas, and I haven't been able to find anyone else with my problem.
我完全没有想法,而且我无法找到任何有问题的人。
As far as I can tell, where it says "You need to install postgresql-server-dev-XY for building a server-side extension or libpq-dev for building a client-side application" it means that you need to install packages on your system for the gems to work. 据我所知,它说“您需要安装postgresql-server-dev-XY来构建服务器端扩展或libpq-dev来构建客户端应用程序”,这意味着您需要安装软件包你的系统让宝石工作。
So on fedora I had to yum install postgresql-devel
. 所以在fedora我不得不
yum install postgresql-devel
。 Since you're on Ubuntu I think you need to do 因为你在Ubuntu上,我认为你需要这样做
sudo apt-get install libpq-dev
You may also need build-essential
so you could run 您可能还需要
build-essential
以便您可以运行
sudo apt-get install libpq-dev build-essential
