使用任何 Heroku 命令时出错
每当我使用任何 Heroku 命令时，我都会收到此错误。到目前为止，这些命令仍然有效，所以我没有考虑太多：
/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31: command not found: git config heroku.remote
但是现在当我尝试 heroku db:pull 时，我收到此错误。不确定两者是否相关，但无论哪种方式，我都可以帮助解决一个或两个问题。

Any time I use any Heroku command I get this error. So far the commands have still worked so I haven't thought much about it:
/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31: command not found: git config heroku.remote
However now when I try heroku db:pull, I get this error. Not sure if the two are related, but either way I could use help solving one or both.

Heroku 在这里（在底部）有一些关于此的信息：
它链接回这篇 StackOverflow 文章（如何元）： 如何在 Ubuntu 中使用 gems？
Heroku has some information on this here (down at the bottom):
And it links back to this StackOverflow article (how meta): How do I use gems with Ubuntu?
我不确定其他错误，但这个错误：
是因为您试图将重复的主键插入表中。但不确定为什么会发生这种情况。
I'm not sure about the other errors, but this one:
is because you are trying to insert a duplicate primary key into a table. Not sure why that is occurring, though.
