Ts-jest: imported package to be 'undefined'

[tanakaworld]

Issue :

In 23.x version when I load the package by import syntax, it will be undefined.

e.g.

import Vue from 'vue';
// `Vue` to be `undefined`

But this is not occurred in 22.4.3.

Expected behavior :

Output from debug log :

# content of debug.txt :

@tanakaworld this is most likely because you're missing the esModuleInterop: true in your tsconfig.json. See https://github.com/kulshekhar/ts-jest/wiki/Troubleshooting#commonjs-compatibility.

You can also try the latest beta if you feel like it (see #697).

Re-open in case that doesn't fix your issue.

fixed by esModuleInterop: true in tsconfig.json

Thanks!
