使用时gem install gem_name我可以通过--no-rdoc并--no-ri切换到跳过为安装时的gem生成RDoc/RI文档.
是否有类似的方法来做到这一点bundle install？
我使用rvm安装了zlib软件包和ruby 1.9.3,但是每当我尝试安装gem时它会说
cannot load such file -- zlib
我以前安装的命令是
$ rvm install 1.9.3
$ rvm pkg install zlib
$ rvm reinstall 1.9.3 --with-readline-dir=/home/username/.rvm/usr \
--with-iconv-dir=/home/username/.rvm/usr \
--with-zlib-dir=/home/username/.rvm/usr \
--with-openssl-dir=/home/username/.rvm/usr
$ rvm use 1.9.3
$ gem install heroku
ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NameError)

关于这个主题的所有帮助告诉我要做rvm pkg install zlib,然后重新安装红宝石--with-zlib-dir=/home/username/.rvm/usr,但这不起作用.
我是Ruby的新手,并试图围绕以下概念:Bundler vs RVM vs gems vs RubyGems vs gemsets vs system rub我很困惑.
有人可以描述一个"最佳实践",说明如何在全新安装最新版本的Ubuntu时管理所有这些内容吗？我应该安装什么,以及如何使用它？
我猜sudo apt-get install ruby不会推荐做一个,但我不确定.除了"所有其他Ruby东西"之外,我在我的系统上尝试过它.这只会增加我的困惑.我不是在谈论Rails,而只是常规的Ruby宝石(例如Vagrant,Chef,脚本).
我正在尝试安装pg gem以便再次使用我的rails项目.但我得到这个错误:
构建原生扩展.这可能需要一段时间...错误:安装pg时出错:错误:无法构建gem原生扩展.

我尝试了在stackoverflow上找到的所有内容,但我仍然遇到此错误.
如果我尝试使用brew安装postgresql,我会得到以下警告:
警告:postgresql-9.2.4已经安装,它只是没有链接
如果我尝试链接
brew链接postgresql链接/usr/local/Cellar/postgresql/9.2.4 ...警告:无法链接postgresql.取消链接...
错误:无法符号链接文件:/usr/local/Cellar/postgresql/9.2.4/share/man/man7/WITH.7/usr/local/share/man/man7不可写.您应该更改其权限.
请帮忙
注意:我已经为小牛队安装了命令行工具.
如果我使用自制程序卸载并尝试再次安装,我收到此错误:

我是红宝石的新手.我尝试按照网站http://rubygems.org/pages/download中给出的步骤在我的电脑上安装GEM .
我从提及站点下载了包,并将目录更改为安装程序所在的目录,并尝试使用命令运行安装程序,
命令提示符下的setup.rb.
但我弹出一个窗口,显示"Windows无法打开此文件"并提示我选择一个程序来打开此文件.
我现在应该怎么做？让我知道,如果我做错了什么..
