umi下ajv6.4.0，无法正常打包，报错

[jy4618272]

ajv6.4.0依赖"uri-js": "^4.2.1"
npm run build报错：
Failed to minify the bundle. Error: src__pages__index__page.d68c9114.async.js from UglifyJs

出错代码为：
// CONCATENATED MODULE: ./node_modules/uri-js/dist/esnext/util.js
function merge(...sets) {
if (sets.length > 1) {
sets[0] = sets[0].slice(0, -1);
const xl = sets.length - 1;
for (let x = 1; x < xl; ++x) {
sets[x] = sets[x].slice(1, -1);
}
sets[xl] = sets[xl].slice(1);
return sets.join('');
}
else {
return sets[0];
}
}
