我认为这是一个常见问题,但是我在互联网上找到的解决方案对我不起作用。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)

Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p194/gems/pg-0.16.0 for inspection.

下一步,根据我的发现,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,并得到这个最终错误....
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,对 Mac 来说也是全新的。任何帮助,将不胜感激。谢谢!
