在CentOS 6上安裝pg gem

[英]Install pg gem on CentOS 6

我正在嘗試使用ruby on rails和postgres設置我的VPS(CentOS 6.4)。

我安裝了ruby(2.1.0p0),rails(4.1.0)和postgresql(9.3.4)沒有問題。

當我嘗試創建新的rails應用程序(rails new new_app -d postgresql)時,它會在安裝pg gem時停止。 我查看了有關此錯誤的所有SO帖子,並嘗試了我能找到的所有內容。 最建議的是運行“yum install postgresql-devel”並仍然無法正常工作。

您可以在下面找到ssh輸出和mkmf.log。 如果需要更多信息,請告訴我......

對於Centos 6 :使用本指南正確安裝Postgres 9. *。

后:

yum install postgresql-libs postgresql-devel

有用的指導:

如何使用Postgres設置RoR

由於您沒有使用CentOS 6(PostgreSQL 8.4)附帶的過時PostgreSQL版本,因此您需要安裝與您的版本匹配的-devel軟件包(PostgreSQL 9.X)。

最簡單的方法是使用官方的PostgreSQL yum存儲庫

由於最新版本是9.5並且它與所有9.X版本兼容,我將編寫該版本的說明。 將來您可以參考更新命令的官方說明

yum install http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-redhat95-9.5-2.noarch.rpm
yum install postgresql95-devel

然后使用-with-pg-config選項安裝gem:

gem install pg -- --with-pg-config=/usr/pgsql-9.5/bin/pg_config

這對我來說更容易:

ln -s /usr/pgsql-9.5/bin/pg_config /usr/local/bin/

嘗試這樣的事情;

before "bundle:install" do
  run "ls -l #{fetch(:latest_release)}/Gemfile"
  #run "bundle config  --local --gemfile=#{fetch(:latest_release)}/Gemfile build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config"
  run "cd #{fetch(:latest_release)} && bundle config build.pg --with-pg-config=/usr/pgsql-9.3/bin/pg_config"
end

您可以嘗試使用postres pg_config文件路徑選項安裝pg gem:

gem install pg -- --with-pg-config=/usr/pgsql-9.2/bin/pg_config

請根據您的系統更新路徑

問候

我在我的Mac上遇到了這個問題,這是一個bash / RVM問題。 我不得不將此添加到我的bash:[[-s“$ HOME / .rvm / scripts / rvm”]] && source“$ HOME / .rvm / scripts / rvm”。鑒於它找到配置文件我會看進入這個。
