gem install pg在进行bundle install / RoR时无法正常工作

修改

对我有用的是：

brew doctor

然后我不得不输入几个文件并删除它要求我的一些内容。

然后我跑了

sudo gem install pg

它有效。不知道为什么它只适用于'sudo'，但是当我尝试之前没有它失败

我使用了捆绑器来安装一堆宝石（大多数都失败了，我花了几个小时查看有关如何安装特定宝石的互联网帖子。

目前正在运行

bundle install

抱怨以下

在另一个堆栈溢出帖子上建议以下内容     以下是我修复它的方法（使用自制程序）：

Install another build of Xcode Tools (typing 'brew update' in the terminal will prompt     you to update the Xcode build tools)
brew update
brew install postgresql

但是当我做的时候

brew install postgresql

我得到以下内容：

Warning: postgresql-9.3.4 already installed, it's just not linked

我找不到涵盖如何执行此操作的帖子。有人可以解释我想如何链接这个吗？或者如何

libpq-fe.h header

我试过

brew uninstall postgresql
brew install postgresql

给了我

brew uninstall postgresql
Uninstalling /usr/local/Cellar/postgresql/9.3.4...


jacks-MacBook-Pro:techendo jsw$ brew install postgresql
==> Downloading https://downloads.sf.net/project/mach
Already downloaded: /Library/Caches/Homebrew/postgresql-9.3.4.mavericks.bottle.2.tar.gz
==> Pouring postgresql-9.3.4.mavericks.bottle.2.tar.g
==> Caveats
If builds of PostgreSQL 9 are failing and you have version 8.x installed,
you may need to remove the previous version first. See:
  https://github.com/Homebrew/homebrew/issues/issue/2510

To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:
  http://www.postgresql.org/docs/9.3/static/upgrading.html

When installing the postgres gem, including ARCHFLAGS is recommended:
  ARCHFLAGS="-arch x86_64" gem install pg

To install gems without sudo, see the Homebrew wiki.

To have launchd start postgresql at login:
    ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
    postgres -D /usr/local/var/postgres
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/man/man3/SPI_connect.3
/usr/local/share/man/man3 is not writable.

You can try again using:
  brew link postgresql
==> Summary
  /usr/local/Cellar/postgresql/9.3.4: 2921 files, 38M

它仍然表示它已安装但没有链接，所以我跑了

brew link postgresql

我得到以下

jacks-MacBook-Pro:techendo jsw$ brew link postgresql
Linking /usr/local/Cellar/postgresql/9.3.4... 
Error: Could not symlink share/man/man3/SPI_connect.3
/usr/local/share/man/man3 is not writable.

有人建议我做

ARCHFLAGS="-arch x86_64" gem install pg

我做了什么
