我认为我已经以正确的方式将标志/选项传递给了命令。 我的步骤有什么问题

感谢您的帮助 绿衫军

Answer 1

你的 V 是最新的吗？我无法重现此行为。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.

这对我来说似乎很正确。

如果您不确定您的 V 是否是最新的（可能不是，因为目前 V 更新周期非常非常短，每天多次），请尝试运行 v up。如果它不起作用，您可能没有按照推荐的方式安装 V，即克隆存储库并暂时从源安装它 (https://github.com/vlang/v#installing-v-from-source)。

绿衫军，试试这个：

• v -x64 run cli.v --times=5 --language english 'How do you feel'
  • -x64-flag 用于 Linux 系统；
  • -g 或 -cg 适用于 MacO；
