Highchart - 预期类型来自 属性 'dashStyle' ,它在此处声明为类型 'XAxisPlotLinesOptions'

Highchart - The expected type comes from property 'dashStyle' which is declared here on type 'XAxisPlotLinesOptions'

我在 highchart 的 xAxis 添加了下面的代码。

plotLines: [
    {
      color: 'grey',
      width: 2,
      dashStyle: 'line'
    }
],

我得到下面的图表,以前我在其他工作中使用 dashStyle,这里只有我得到下面的问题。

error TS2769: No overload matches this call.
      Overload 1 of 2, '(options: Options, callback?: ChartCallbackFunction): Chart', gave the following error.
        Type '"trgt-testcntrl"' has no properties in common with type 'Options'.
      Overload 2 of 2, '(renderTo: string | HTMLElement, options: Options, callback?: ChartCallbackFunction): Chart', gave the following error.
        Type '"line"' is not assignable to type 'DashStyleValue'.

node_modules/highcharts/highcharts.d.ts:115249:5
        115249     dashStyle?: DashStyleValue;
                   ~~~~~~~~~
        The expected type comes from property 'dashStyle' which is declared here on type 'XAxisPlotLinesOptions'

我做错了什么?

没有 line.
