问 'number‘类型的参数不能赋值给'string’类型的参数- Typescript和Angular

EN

我有这样的编码：

        this.arrayTemp = [];
          interface tempFull {
             num: number;
             name: string;
          for (const key in group) {
              let temp = {} as tempFull;
             temp.num = parseInt(group[key].length / this.item);
             temp.name = group[key][0];
             if (temp.num >= 1){
               this.arrayTemp.push(temp);
          }

对象 Group 是这样的：

{
red:[
 "red",
 "red",
 "red",
blue:[
 "blue",
 "blue",
