Vue Js :找不到这种依赖：*core-js/fn/诺言

Question

我有一个Vuejs应用程序使用的承诺，但得到这个错误：This dependency was not found: core-js/fn/promise in ./src/store/index.js To install it, you can run: npm install --save core-js/fn/promise我的package.json：

"dependencies": {
    "axios": "^0.21.1",
    "bootstrap": "^4.5.3",
    "core-js": "^3.6.5",
    "jquery": "^3.5.1",
    "popper.js": "^1.16.1",
    "vue": "^2.6.11",
    "vue-axios": "^3.2.2",
    "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",
    "vue-template-compiler": "^2.6.11"
  },

我运行了save core-js/fn/以外的命令，但是没有任何改变。

Answer 1

我今天有同样的错误，原因是import { reject } from "core-js/fn/promise"，我删除它，然后应用程序编译成功。

Answer 2

尝试通过以下方式更新您的core-js依赖关系版本：

npm install core-js
// or
yarn add core-js

错误是由于yourProject/node_modules/core-js与您的代码不同步造成的。

您正在导入core-js/fn/promise，但是构建工具没有找到它。

当我试图启动一个Vue应用程序时，也遇到了类似的问题：

core-js/modules/es6.array.find in ./src/state/helpers.js,
* core-js/modules/es6.function.name in ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/_base-link.vue?vue&type=script&lang=js&, ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/_base-icon.vue?vue&type=script&lang=js& and 4 others
...
..
..

我的修正是更新依赖项，下一个是更新后的package.json：

{
 ...
 "dependencies": {
  "core-js": "^2.6.12",
  "vue": "2.5.16"
 },
 "devDependencies": {
  "@babel/core": "^7.14.6",
 }
}
