当有人说"编辑您的.plist文件"或"您的.profile"或".bash_profile"等时,这只会让我感到困惑.我不知道这些文件在哪里,如果我必须这样做,如何创建它们等,以及为什么似乎有这么多不同的(为什么？他们做不同的事情？)
那么,有人可以非常耐心地向以前的Windows用户解释(想要更加熟悉令人愉快的,如果最初有些令人困惑的OS X世界)如何一步一步地做到这一点？
我需要为GUI应用程序和命令行应用程序设置变量,目前它是需要变量的ant脚本,但很可能还有其他需求.
请注意我也有狮子,因为谷歌的许多答案似乎已经过时了......
另请注意,我几乎没有使用终端的经验.我愿意学习,但请为新手解释...
我有2个Ruby版本:1.8.7和1.9.2以及PostgreSQL 8.3.我不能在任何一个上安装pg gem.得到此错误:
C:/Development/Ruby187/bin/ruby.exe extconf.rb
checking for pg_config... yes
not recorded
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir

--with-pg-dir
--without-pg-dir
--with-pg-include
--without-pg-include=${pg-dir}/include
--with-pg-lib

我知道这是一个常见的问题,但我还没有找到任何有效的解决方案...哦,我已经将C:\ Program Files(x86)\ PostgreSQL\8.3\bin添加到我的PATH中.
我正在尝试部署到heroku.
Rails 3.1.0.rc4,
我从Heroku日志中收到以下错误:
Starting process with command: `thin -p 48902 -e production -R /home/heroku_rack/heroku.ru start`
2011-06-20T11:25:44+00:00 app[web.1]: /app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_specification.rb:71:in `rescue in establish_connection': Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.) (RuntimeError)
我试图安装activerecord-postgresql-adapter,但后来我收到此错误:
Could not find gem 'activerecord-postgresql-adapter (>= 0)' in any of the gem sources listed in your Gemfile.
所以我试着将它添加到我的gem文件中
宝石'pg'
产生了这个错误:
