我正在尝试安装pg-native软件包：
sudo npm install pg-native
但会产生以下错误：
> libpq@1.7.0 install /Workspace/auth/node_modules/libpq
> node-gyp rebuild
/bin/sh: pg_config: command not found
gyp: Call to 'pg_config --libdir' returned exit status 127. while trying to load binding.gyp

npm WARN install:libpq Exit status 1
我尝试通过安装node-gyp模块然后手动运行重建命令来解决这个问题：
sudo npm install -g node-gyp
sudo node-gyp rebuild
我读到这个问题在更新的 Node 版本中不再存在，所以我更新到 version v4.1.1。
我还尝试将模块本地安装到工作区和全局安装到机器的其余部分，但仍然没有运气。运行node-gyp正常，所以看起来已经正确安装。
对此问题的任何帮助将不胜感激！
