Visual studio code Can'；在vscode任务版本2.0.0中运行npm任务

我有package.json和任务：start脚本

"scripts": {
    "task:start": "rm -rf bin && npm run prepare_env && npm run build",
    "prepare_env": "bash ../scripts/prepare-node-modules.sh",
    "build": "tsc --watch"
},

我想用build命令在vscode任务中准备整个环境。 我正在为vscode尝试新的2.0.0版本的task，但npm task不起作用

"version": "2.0.0",
    "tasks": [
        {
            "type": "npm",
            "script": "task:start",
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]

输出为：

> Executing task: npm run task:start <


Usage: npm <command>

where <command> is one of:
    access, adduser, bin, bugs, c, cache, completion, config,
    ddp, dedupe, deprecate, dist-tag, docs, edit, explore, get,
    help, help-search, i, init, install, install-test, it, link,
    list, ln, login, logout, ls, outdated, owner, pack, ping,
    prefix, prune, publish, rb, rebuild, repo, restart, root,
    run, run-script, s, se, search, set, shrinkwrap, star,
    stars, start, stop, t, tag, team, test, tst, un, uninstall,
    unpublish, unstar, up, update, v, version, view, whoami

npm <cmd> -h     quick help on <cmd>
npm -l           display full usage info
npm help <term>  search for help on <term>
npm help npm     involved overview

Specify configs in the ini-formatted file:
    C:\Users\Dariusz\.npmrc
or on the command line via: npm <command> --key value
Config info can be viewed via: npm help config

npm@3.10.10 C:\Program Files\nodejs\node_modules\npm

但我想用新的。我的配置：

• vscode 1.15.1
• 视窗10

这件事已经太晚了，但有一个问题已经解决了。尽管有一条关于修复的评论是“如果我切换回cmd终端，它确实可以工作”，但这已经太晚了，但有一个关于这个的问题已经解决了。尽管有一条关于修复的评论是“如果我切换回终端的cmd，它确实可以工作。”`
