运行 bundle install 时如何传递 gem 安装参数? [英] How can I pass a parameter for gem installation when I run bundle install?

问题描述

我将 pg gem 添加到我的 gemfile

I added the pg gem to my gemfile

gem 'pg'

当我运行 bundle install 时，我收到此错误:

When I run bundle install, I get this error:

Installing pg (0.10.1) with native extensions /Users/ben/.rvm/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/rubygems/installer.rb:483:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

/Users/benhartney/.rvm/rubies/ruby-1.9.2-p0/bin/ruby extconf.rb

No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config

Could not create Makefile due to some reason, probably lack of

details.  You may need configuration options.

看来我需要传入这个配置参数

It seems I need to pass in this config parameter

 --with-pg-config=/path/to/pg_config

当我使用 bundle install 时，我该怎么做?

How can I do this when I use bundle install?

推荐答案

您需要像这样设置构建配置选项:

You need to set a build config option like so:

bundle config build.pg --with-pg-config=/path/to/pg_config
