我想通过定义一些输入变量来使用 Visual Studio Code 定义可配置任务。
在我的特定情况下，我希望一项任务取决于带有子句
${input:package_manager}"dependsOn": ["${input:package_manager}"]但是，这样的设置会输出错误：
Activating task providers all
Couldn't resolve dependent task '${input:package_manager}' in workspace folder 'vscode-remote://
从文档可以清楚地看出，并非所有字段都支持输入变量：
并非tasks.json中的所有值都支持变量替换。具体来说，只有 command、args 和 options 支持变量替换。输入部分中的输入变量将不会被解析，因为不支持输入变量的嵌套
但是根据用户输入选择任务的替代方法是什么？

我还没有测试过它，但你可以了解如何实现它。
您也许可以使用 extension.commandvariable.pickStringRemember 的
Multi Pick选项并记住某些选项的多个字符串，并使用
__key
