我刚刚安装Rails 4.0.2并在创建新应用时,在捆绑阶段我得到:
Installing pg (0.17.1)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

我该如何解决？
当我跑(以root身份)
gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config
我得到以下输出:
#-> gem instal pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config
Building native extensions. This could take a while...
Successfully installed pg-0.12.0

当我运行bundle install时:

我有一个新的macbook,我正在寻找一个现有的应用程序.当我克隆应用程序时,它不会捆绑安装,并且没有安装Rails,即使它在其他目录中工作.
我尝试从gemfile中删除版本号并删除gemfile.lock.我尝试了捆绑更新.我在osx 10.9.4,rails 4.1.5和ruby 2.1.1上.
我得到的错误:
An error occurred while installing nokogiri (1.6.3.1), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.6.3.1'` succeeds before bundling.
我安装了rvm.我尝试重新安装自制软件,rails和ruby.
会是什么呢？
当运行bundle install(或gem install pg)时,我得到以下错误,我已经尝试修复xcode命令行工具

我创建了一个新的rails应用程序:rails new -d postgresql
但是,我无法安装pg gem.我之前使用brew安装了postgres,它会自动启动我的Mac.
我已经尝试了几个在这里发布的东西.我正在使用ruby 2.0.运行bundle install时,我收到错误:
Errno :: EACCES:权限被拒绝 - /Library/Ruby/Gems/2.0.0/gems/pg-0.17.1/.gemtest
安装pg(0.17.1)时发生错误,Bundler无法继续.
gem install pg -v '0.17.1'在捆绑之前确保成功.
我尝试下载postgresapp,但是当我尝试启动它时,有一个明显的冲突b/c它说:无法启动5432端口.不确定这是否导致问题.
我也试过这个:
sudo env ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-
config=/Users/david/Library/Application Support/Postgres/var-9.3/postgresql.conf
并得到错误:无法构建gem原生扩展.
我是一个相当新的程序员,所以请在回复中尽可能详细. 谢谢!
固定:我遵循贾斯汀的建议,然后重新启动.在那之后,我重新'捆绑安装'并最终安装了pg gem!
