vue-template-compiler must be installed as a peer dependency, or a compatible compiler implementatio

升级webpack3 ->4 导致的报错
Module Error (from ./node_modules/vue-loader/lib/index.js):
[vue-loader] vue-template-compiler must be installed as a peer dependency, or a compatible compiler implementation must be passed via options.

后来发现是vue和vue-template-compiler版本不一致导致的，重新下一个同版本包就可以了

"vue": "^2.6.10",
"vue-template-compiler": "^2.6.10"，
