Axios 已定义但从未使用

Question

import axios from "axios";在我的App.vue文件中导入 axios 后，出现axios is defined but never used错误。我附上了错误图片和package.json代码。我安装了axios. 如何解决？

package.json 文件是：

{
  "name": "myvue",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "@mdi/font": "^3.6.95",
    "@vue/test-utils": "^1.0.0-beta.29",
    "axios": "^0.19.0",
    "core-js": "^3.3.2",
    "material-design-icons-iconfont": "^5.0.1",

    "roboto-fontface": "*",
    "vue": "^2.6.10",
    "vuetify": "^2.1.10"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "^4.0.0",
    "@vue/cli-plugin-eslint": "^4.0.0",
    "@vue/cli-service": "^4.0.0",
    "babel-eslint": "^10.0.3",
    "eslint": "^5.16.0",
    "eslint-plugin-vue": "^5.0.0",
    "sass": "^1.19.0",
    "sass-loader": "^8.0.0",
    "vue-cli-plugin-vuetify": "^2.0.2",
    "vue-template-compiler": "^2.6.10",
    "vuetify-loader": "^1.3.0"
  }
}

Answer 1

您可以通过更新package.json文件来解决此问题，"eslintConfig"如下所示：

...

"rules": {
  "no-console": "off",
  "no-unused-vars": "off"
}

...

Answer 2

这与其说是错误，不如说是警告，但它已设置为您的eslint文件中的错误。

只能说你没用 axios但你进口了它。该 lint 规则只是确保您使用已定义的每个变量。

这是该规则的文档：https : //eslint.org/docs/rules/no-unused-vars
