Vlang cli示例不能以直观的方式工作

Question

我在使用vlang cli库时玩得很开心，第一次接触时，我从v源代码的示例目录中开始玩。你可以在这里看到，vlang cli，我正在努力掌握如何让这些例子工作。让我来显示输出我正在尝试的命令

$ v run ./examples/cli.v
Usage: cli [flags] [commands]

An example of the cli library.

Flags:
  -help               Prints help information.

我想我已经以正确的方式将flag/option传递给了命令。我的脚步怎么了？

谢谢你的帮助绿衫

Answer 1

你的V是最新的吗？我不能重现这种行为。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.

这在我看来是非常正确的。

如果你不确定你的V是否是最新的(可能不是，因为V的更新周期很短，一天要更新好几次)，试着运行v up。如果它不能工作，你可能没有按照推荐的方式安装V，那就是现在克隆存储库并从源代码安装(https://github.com/vlang/v#installing-v-from-source)。

绿衫，试试这个：

用于Linux systems;

• -g的
• v -x64 run cli.v --times=5 --language english 'How do you feel'
  • -x64-flag或用于MacOs;
