我正在尝试为 tcl/wish 程序编写一个参数解析器。
我正在研究https://stackoverflow.com/questions/24341141/package-for-parsing-argument-in-tclgetopts它建议使用通过包实现的实现，但我在第一个障碍面前就失败了。
他们建议使用命令package require cmdline，但我收到错误消息can't find package cmdline。我正在使用“Ubuntu 22.04.1 LTS”，安装程序安装了 TCL。
我不清楚包裹是否丢失，或者我是否写错了。
为什么会发生这种情况？我该如何解决？
我曾尝试使用其他人的代码作为内联过程，但这对我来说还没有作用！

在明确操作系统版本后，我做了apt cache show tcl
$ apt-cache show tcl
Package: tcl

你不需要自己实现这个包——cmdline 是作为 Ubuntu 的一部分提供的库包裹：
$ apt show tcllib
Package: tcllib
Version: 1.20+dfsg-1
