Describe the bug

I use typescript to write weex vue,the compiled code is like:

 function Example(params) {
                        var _this = _super.call(this, params) || this;
                        _this.infoKey = 'weex';
                        return _this;
                    }

                    Example.prototype.created = function () {
                        modal.toast({
                            message: typeof vue__WEBPACK_IMPORTED_MODULE_1___default.a
                        });
                    };

There is a js error _super.call is undefined

Here is the compiled file:

I also see the pre-build vue version 2.5.16,but the package.json weex-vue-framwork 2.5.13-weex.5"

"Start JS Framework 0.29.1, Build at 2018-12-19 16:07. (Vue: 2.5.16-weex.5, Rax: 0.4.20)");

So,where are the vue source?

Add any other context about the problem here.

I think the problem may be:

import * as Vue from 'vue'

instead of:

import Vue from 'vue'
