我正试图用rvm设置乘客.我一直收到这个错误

您的RVM包装器脚本太旧了.请先运行'rvm update --head && rvm reload && rvm repair all'来更新它们.

我做到了同样的问题

• GNU C++编译器...在/ usr/bin/g ++中找到
• 发现了支持SSL的卷曲开发标题
• 找到OpenSSL开发头文件
• 找到了Zlib开发头文件
• 发现了Ruby开发头文件
• OpenSSL支持Ruby ...找到了
• RubyGems ......找到了

您的RVM包装器脚本太旧了.

请先运行'rvm update --head && rvm reload && rvm repair all'来更新它们.

我正在使用Fedora 14,Ruby 1.9.2,Rails 3.0.7 RVM是为多用户安装的

当我'乘客开始'时,我也会收到此错误

无法执行'/home/antarr/.passenger/standalone/3.0.7-x86_64-ruby1.9.2-linux-gcc4.5.1-1002/support/helper-scripts/prespawn http://0.0.0.0:3000 ':权限否认(13)

我正在创建一个rake exe来为xcode项目增加覆盖率.我正在使用Gem xcodeproj.我需要为版本控制创建一些方案并运行覆盖脚本.

我一直在建立自己的计划,而且进展缓慢.如果我理解这些元素的含义,我觉得我能够更快地调试.

我正在尝试为我的WCF应用程序创建服务主机.当我启动应用程序时,我收到错误消息

该服务无法启动.此服务没有定义端点.请在配置文件中为服务添加至少一个端点,然后重试.

我按照PluralSight上的教程进行操作,这是我提出的代码

有没有办法保持我的Ackerman函数不会创建一个堆栈溢流是对相对较小的数字,即(4,2).这是错误

{无法计算表达式,因为当前线程处于堆栈溢出状态.}

private void  Button1Click(object sender, EventArgs e)
        {
            var t = Ackermann(4,2);
            label1.Text += string.Format(": {0}", t);
            label1.Visible = true;
        }

        int Ackermann(uint m, uint n)
        {
            if (m == 0)
                return  (int) (n+1);
            if (m > 0 && n == 0)
                return Ackermann(m - 1, 1);
            if (m > 0 && n > 0)
                return Ackermann(m - 1, (uint)Ackermann(m, n - 1));
            else

我正在使用simple_form来管理我的用户.为了选择用户角色,我使用输入为:: radio_button.

该集合来自用户模型的枚举.如何修改文本以显示特定的内容,如"超级管理员"而不是super_admin？

_form.html.slim

= form.input :role, collection: User.roles, as: :radio_buttons, item_wrapper_class: 'btn btn-default', checked: User.roles[user.role], required: true

user.rb

  enum role: [:super_admin, :admin, :generic]
