Ruby Gem安装pg工作，但bundle安装失败

关于这方面的话题很多，但我已经尝试了几乎所有的话题，但都没有成功

我在Mac OS X 10.9.4 Mavericks上，我有Postgres.app，它可以正常工作，

sudo gem install pg

也可以工作：

Building native extensions.  This could take a while...
Successfully installed pg-0.17.1
invalid options: -f fivefish
(invalid options are ignored)
Parsing documentation for pg-0.17.1
Done installing documentation for pg after 2 seconds
1 gem installed

但是当我尝试

捆绑安装时

我的错误与其他人的错误相同

• 我已经尝试了

  bundle config build.pg——使用pg config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_-config

  然后

  bundle安装

• 我有Xcode命令行工具

• 哪个psql

  返回

  /Applications/Postgres.app/Contents/Versions/9.3/bin/psql

• 哪些postgres

  返回

  /Applications/postgres.app/Contents/Versions/9.3/bin/postgres

以下是

捆绑包安装的错误：

An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

几天后，我终于找到了问题的根源（讽刺的是，当我决定放弃，继续前进时）

当我做一个
哪个捆绑包和
哪个gem
它们不是来自同一个ruby安装。
bundle来自rbenv，gem来自预安装的ruby on mac osx。
可能存在权限问题。可以使用：

sudo bundle安装--没有任何内容--路径供应商/缓存
您能更详细地介绍一下吗？我也有同样的问题-您采取了哪些步骤来解决这个问题？如果我的记忆良好，我会用rbenv重新安装所有这些步骤。宝石包也是
