ruby - 在 Mac OSX 上安装 1.9.3 后显示 Ruby 1.8.7

Question

我以为我已经安装了 ruby​​ 1.9.3-p327。但是当我执行 ruby​​ -v 时，它仍然输出 1.8.7，如下所示。

怎么了？

我使用 OSX 10.7.5 并安装了 osx-gcc-installer 和 Xcode 4.5.2。

更新:我检查了/User/teacher/.rvm/bin/folder，发现有 ruby​​-1.9.3 文件。

使用rvm install 将下载并编译一个ruby 版本，但您仍然需要声明您要使用哪个版本。

尝试:

$ rvm use 1.9.3-p327

切换到您新安装的 ruby​​ 版本。要切换版本并设置为默认版本:

$ rvm --default use 1.9.3-p327

rvm website有一些包含更多信息的很棒的文档。
