The error message "TS2304: Cannot find name 'object'" usually occurs when TypeScript is unable to find the object keyword in the code that is causing the error.

In this case, the error message is indicating that TypeScript is unable to find the object keyword in the file echarts\index.d.ts, which is a TypeScript definition file for the echarts library.

To fix this error, you need to ensure that the object keyword is defined in the code that is causing the error. If the object keyword is defined elsewhere in the code, you can simply include it in the file that is causing the error using the following line: typescript import { object } from 'echarts';

Alternatively, if the object keyword is defined elsewhere in the code, you can provide an import statement for it in the file that is causing the error. For example: typescript import { object } from 'echarts'; import * as echarts from 'echarts';

Note that the * as syntax is used to provide an import statement for the object keyword in case it is defined elsewhere in the code.
