错误如下:
error in ./src/Utils.vue Module build failed: Error: Vue packages version mismatch: - vue@2.5.13 - vue-template-compiler@2.5.17 This may cause things to work incorrectly. Make sure to use the same version for both. If you are using vue-loader@>=10.0, simply update vue-template-compiler. If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.
解决方法很简单,打开node-modules文件夹,将跟报错那个包的文件夹删掉,然后重装跟vue一致的版本
