ruby - 1.9.3 安装，报错信息 factory_girl requires Ruby version >= 1.9.2

Question

我刚刚用 ruby​​ 1.9.3 安装了 rbenv

rbenv version
1.9.3-p327 (set by /Users/me/.rbenv/version)

但是，当我尝试运行 bundle update(在安装 rbenv 之前创建的项目中)时，我收到一条错误消息，指出 factory_girl 至少需要 ruby​​ 1.9.2。请参阅下面的错误消息

如果相关，当我执行 gem --version 时，我会看到对 1.8.23 的引用。

gem --version
1.8.23

错误信息

更新:

第一个答案告诉我要做三个步骤

gem install bundle
rbenv rehash
bundle install

我做了那些步骤(它安装了 bundler )'

gem install bundler
Fetching: bundler-1.2.3.gem (100%)
Successfully installed bundler-1.2.3
1 gem installed

但是当我尝试“捆绑安装”时，我收到了关于 Factory_girl 的相同错误消息。有趣的是，我决定再次尝试这三个步骤，从 gem install bunlder 开始，它又安装了一次？!#？？

Answer 1

您正在使用的 bundle 命令来自系统 Ruby 安装，即 Ruby 1.8.x。

尝试

1. gem 安装 bundler
2. rbenv 重新哈希
3. 捆绑安装

这应该可以解决您的问题。
