我正在尝试安装pg gem以便再次使用我的rails项目.但我得到这个错误:

构建原生扩展.这可能需要一段时间...错误:安装pg时出错:错误:无法构建gem原生扩展.

/Users/jeanosorio/.rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb checking for pg_config... no No pg_config... trying anyway. If

构建失败,请再次尝试使用--with -pg-config =/path/to/pg_config检查libpq-fe.h ...否找不到'libpq-fe.h header *extconf.rb失败*由于某些原因无法创建Makefile,可能缺少必要的库和/或标头.检查mkmf.log文件以获取更多详细信息.您可能需要配置选项.

提供的配置选项: - with-opt-dir --without-opt-dir --with-opt-include --without-opt-include = $ {opt-dir}/include --with-opt-lib - without-opt-lib = $ {opt-dir}/lib --with-make-prog --without-make-prog --srcdir =.--curdir --ruby =/Users/jeanosorio/.rvm/rubies/ruby​​-2.0.0-p247/bin/ruby​​ --with-pg --without-pg --with-pg-config --without-pg -config --with-pg_config --without-pg_config --with-pg-dir --without-pg-dir --with-pg-include --without-pg-include = $ {pg-dir}/include - -with-pg-lib --without-pg-lib = $ {pg-dir} /

Gem文件将保留在/Users/jeanosorio/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/gems/2.0.0/gems/pg-0.17.0中进行检查.结果记录到/Users/jeanosorio/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/gems/2.0.0/gems/pg-0.17.0/ext/gem_make.out

我尝试了在stackoverflow上找到的所有内容,但我仍然遇到此错误.

如果我尝试使用brew安装postgresql,我会得到以下警告:

警告:postgresql-9.2.4已经安装,它只是没有链接

如果我尝试链接

brew链接postgresql链接/usr/local/Cellar/postgresql/9.2.4 ...警告:无法链接postgresql.取消链接...

错误:无法符号链接文件:/usr/local/Cellar/postgresql/9.2.4/share/man/man7/WITH.7/usr/local/share/man/man7不可写.您应该更改其权限.

请帮忙

注意:我已经为小牛队安装了命令行工具.

如果我使用自制程序卸载并尝试再次安装,我收到此错误:

我在osx 10.6.7尝试在新的rails 3.0.7应用程序上运行bundle install,并且在尝试构建pg gem时它仍然失败.它一直告诉我,我需要开发人员工具.但据我所知,我已经安装了开发人员工具.

这是xcodebuild -version的输出

Xcode 3.2.6
Component versions: DevToolsCore-1809.0; DevToolsSupport-1806.0

这是失败的pg gem构建的输出
