import失败，提示export 'default' (imported as 'impl') was not found in '../proto/proto.min' #4
Description
原因是proto.min.js和base64.min.js不需要通过babel转换，需要在babel的配置文件中将这两个文件忽略。
.babelrc参考配置如下：
{
"presets": [
["env", {
"modules": false,
"targets": {
"browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
}
}],
"stage-2"
],
"plugins": ["transform-vue-jsx", "transform-runtime"],
"ignore": [
"**/base64.min.js",
"**/proto.min.js",
"**/engine.min.js"
]
}
