visual-studio-code - 在 vscode for WSL 中的 task.json 中设置环境变量

Question

我尝试为将在我的 Windows 子系统 Linux 中运行的 Visual Studio Code 任务设置环境变量。但是，它似乎不起作用。这是我的tasks.json:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "test env",
            "type": "shell",
            "command": "echo",
            "args": [
                "$test"
            ],
            "options": {
                "env": {
                    "test": "test_string"
                }
            }

        },
    ]
}

输出是:

> Executing task in folder ex12-test: echo $test <



Terminal will be reused by tasks, press any key to close it.

请注意，默认情况下 shell 已手动修改为 C:\WINDOWS\SysNative\bash.exe用于 WSL，如推荐 here和 here .

选项对象在任何任务之外，所以:

format
  "version": "2.0.0",
  "options": {
      "env": {
        "test": "test_string"
      }
   }
   "tasks": [
    {
        "label": "test env",
        "type": "shell",
        "command": "echo",
        "args": [
            "$env:test"
        ],
    },

然后像这样访问选项参数:

$env:test  or    ${env:test}
]
