Question

我正在尝试安装pg gem。

bens-macbook-pro:liferecord ben$ bundle config build.pg --with-pg-config=/users/ben/postgresql/bin
bens-macbook-pro:liferecord ben$ bundle install

我收到此错误：

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)

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

    --with-pg-config
extconf.rb:13:in ``': Permission denied - /users/ben/postgresql/bin --includedir (Errno::EACCES)
    from extconf.rb:13:in `<main>'

导致此错误的原因是什么？

额外信息：

我从one click installer安装了PostgreSQL。

这是我指向pg-config的目录的输出：

bens-macbook-pro:bin ben$ ls

我正在跑步：

Rails 3.0.1

如果其他人遇到此问题，则错误是由此引起的：

bundle config build.pg --with-pg-config=/users/ben/postgresql/bin

应该是

bundle config build.pg --with-pg-config=/users/ben/postgresql/bin/pg_config

当我尝试安装pg gem时导致此错误的原因是什么？
