typescript / webpack报错“can only be default-imported using the 'esModuleInterop' flag

原因:This module is declared with using 'export =', and can only be used with a default import when using the 'esModuleInterop' flag.

解决:

import request = require('request');
//或
import * as request from 'request';

后来在webpack时报错很多modules里文件的这个错:

typescript / webpack报错“can only be default-imported using the 'esModuleInterop' flag

解决:

在tsconfig.json里添加

"esModuleInterop": true
