Ruby 1. 9+样式 hash 语法无效
原标题:Ruby 1.9+ style hash syntax doesn t work

我在我的Macbook上运行着1.9.3p194(2012-04-20修订版35410)[x86_64-darwin11.4.0]。

然而,当我试图使用“新风格”的杂乱无章,例如:

stylesheet_link_tag "application", media: "all"

我有一个错误, 读到 “ 意外: 期待 ”

我可以用"老式"的杂碎来解决这个问题:

stylesheet_link_tag "application", :media => "all"

我想弄清楚铁路为什么不允许 红宝石杂交的新风格。任何帮助都会非常感激。

问题回答

听起来像是铁路在系统红宝石下运行,而RVM安装为1.9.3(我猜想)

尝试

$ rvm --default use 1.9.3

然后重置控制台,然后做

$ ruby -v

双检查

尝试在您的. bash_ profile (或bashrc 或任何您正在使用的) 中放置这个 :

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

在此之后,当然,发出源命令,然后:

rvm use 1.9.2
rvm info

这应该起作用, 并显示关于当前红宝石版本和宝石设置的所有信息。 新的大麻语法因您没有实际运行红宝石1.9. 3而失效。 做“ ruby - v” 应该能证实问题。 根据上述评论, 您 rvm < strong > has 将是一个功能, 以便它运作 。

还有,你在运行什么操作系统?
