我正在使用 angular 9 并添加了 angular 材料，但是当我想使用 mat-select 时，我无法选择该选项并出现以下错误。

core.js:6241 ERROR TypeError: Cannot read property 'pipe' of undefined
    at MatSelect.ngAfterContentInit (select.js:609)
    at callHook (core.js:4726)
    at callHooks (core.js:4690)

我有两个数组列表，我不知道如何在 python 中合并多个对象数组？

[{'name': 'James'}, {'name': 'Abhinay'}, {'name': 'Peter'}]

[{'age': 1}, {'age': 2}, {'age': 3}]

我想要的是

[{'name': 'James','age':1}, {'name': 'Abhinay','age':2}, {'name': 'Peter','age':3}]
