Question

我认为这是一个常见的问题，但我在互联网上找到的解决方案并不适用于我。当我在我的gemfile

中使用此部分运行bundle install时

group :production, :staging do
  gem "pg"
end

group :development, :test do
  gem "sqlite3-ruby", :require => "sqlite3"
end

我收到以下错误

creating Makefile

make
compiling gvl_wrappers.c
compiling pg.c
pg.c: In function ‘Init_pg_ext’:
pg.c:375: error: ‘PQPING_OK’ undeclared (first use in this function)
pg.c:375: error: (Each undeclared identifier is reported only once
pg.c:375: error: for each function it appears in.)
pg.c:377: error: ‘PQPING_REJECT’ undeclared (first use in this function)
pg.c:379: error: ‘PQPING_NO_RESPONSE’ undeclared (first use in this function)
pg.c:381: error: ‘PQPING_NO_ATTEMPT’ undeclared (first use in this function)
make: *** [pg.o] Error 1


Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p194/gems/pg-0.16.0 for inspection.
Results logged to /usr/local/rvm/gems/ruby-1.9.3-p194/gems/pg-0.16.0/ext/gem_make.out

根据我发现的，下一步是运行locate pg_config，然后将位置放在gem install pg命令行语句之后。但是，我得到了这个错误：

WARNING: The locate database (/var/db/locate.database) does not exist.
To create the database, run the following command:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

Please be aware that the database can take some time to generate; once
the database has been created, this message will no longer appear.

然后我运行sudo命令，并得到最后的错误....

launchctl: Couldn't stat("/System/Library/LaunchDaemons/com.apple.locate.plis"): No such file or directory
nothing found to load

这是我第一次尝试使用这项技术，也是Mac的全新技术。任何帮助，将不胜感激。谢谢！

看起来尽管你的宝石文件说的是什么，但是你想尝试在本地安装postgres？

真的，那就是你应该做的。将生产中的其他数据库用于本地使用的数据库实际上并不是最佳的。我强烈建议在任何地方使用Postgres，并删除sqlite。

在Mac上，通往此天堂的最简单方法是安装Postgress.app
