现象
import Nerv, { Component } from 'nervjs'
class A extends Component {
...
}
Chrome下运行正常,在IE 8下运行P抛错new TypeError('Super expression must either be null or a function')
例外被抛出未接住
一种解决方法:
import Nerv from 'nervjs'
class A extends Nerv.Component {
...
}
请问是否能从Nerv本身层面解决这个问题?

应该是 babel 设置的问题, 把 class-properties
的 spec
打开:
// .babelrc
{
"plugins": [
["transform-class-properties", { "spec": true }]
]
}

使用https://github.com/NervJS/nerv-webpack-boilerplate.
"plugins": [
["@babel/plugin-proposal-class-properties", { "loose": true }],
]
不论loose是否打开 IE8都报错

你的component有super了吗 是component创建失败吧

参考 https://github.com/womendi/nervjs-ie8
package.json中build只写webpack就好,不要加--config *.js
