Command line Vlang cli示例不能以直观的方式工作

我在vlang cli库中玩得很开心，第一次接触时，我从v源代码的examples目录中开始玩。你可以在这里看到 我正在努力掌握如何让这些例子发挥作用。让我显示我正在尝试的命令

我想我已经以正确的方式将标志/选项传递给了命令。 我的脚步怎么了

谢谢你的帮助 绿衫

绿衫，试试这个：

• v-x64 run cli.v--times=5--language英语“感觉如何”

  • -x64

    -用于Linux系统的标志
  • MacOs的

    -g

    或

    -cg

您的V是最新的吗？我无法复制这种行为。例如：

$ v run ./examples/cli.v greet painem
Flag `language` is required by `cli greet`
$ v run ./examples/cli.v greet --language english painem
This is a function running before the main function.

Welcome painem
Welcome painem
Welcome painem

This is a function running after the main function.

我觉得这很正确

如果您不确定您的V是否是最新的（可能不是，因为当前V更新周期很短，每天多次），请尝试运行

V up

。如果它不起作用，那么您可能没有按照建议的方式安装V，也就是克隆存储库并立即从源代码安装（）
