1. 问题原因

今天用vue-cli搭建了一个脚手架 发现 let / await / async 关键字不能用会直接报错

token.type.endsWith is not a function 

    async / await 会报错 删除了就好了. let 也不好用 换成var就好用了 这就很奇怪

 

 2. 问题排查

   排查了很久发现是eslint的问题, 然后各种百度, 发现有个 issue 讨论过这个问题

   这是我之前的package.json

{
  "name": "orion-ops-vue",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "serve:dev": "vue-cli-service serve --mode development",
    "serve:prod": "vue-cli-service serve --mode production"
  },
  "dependencies": {
    "ant-design-vue": "^1.7.8",
    "axios": "^0.23.0",
    "core-js": "^3.6.5",
    "js-md5": "^0.7.3",
    "vue": "^2.6.11",
    "vue-router": "^3.2.0",
    "vuex": "^3.4.0"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-plugin-router": "~4.5.0",
    "@vue/cli-plugin-vuex": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "@vue/eslint-config-standard": "^5.1.2",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-import": "^2.20.2",
    "eslint-plugin-node": "^11.1.0",
    "eslint-plugin-promise": "^4.2.1",
    "eslint-plugin-standard": "^4.0.0",
    "eslint-plugin-vue": "^6.2.2",
    "less": "^3.0.4",
    "less-loader": "^5.0.0",
    "vue-template-compiler": "^2.6.11"
  }
}

3. 问题解决

直接把 babel-eslint 降级, 写死为 ^8.2.2

更改前: "babel-eslint": "^10.1.0",

更改后: "babel-eslint": "^8.2.2",


删除 node_modules
yarn install
问题解决

   还是版本的原因, 降级还有一些其他兼容性问题, 但是是小问题, 稍微改一改就好了

   这个问题还是挺坑的!!!
