使用npm安装lodash为什么会安装两个版本的lodash

Question

package.json只有这一处出现lodash

"dependencies": {

    "element-ui": "1.4.6",

    "font-awesome": "^4.7.0",

    "highcharts": "^v5.0.12",

    "lodash": "^4.17.4",

    "moment": "^2.18.1",

    "normalize.css": "^6.0.0",

    "vue": "2.4.2",

    "vue-router": "^2.2.0",

    "vuex": "^2.2.1",

    "vuex-router-sync": "^4.1.2"

  },

删除了node_modules重新安装还是这样

Answer 1

可能你的某个依赖，比如log4js依赖了3.10.1版本的lodash，而你的代码依赖了4.17.4的版本,就会出现这个情况可以find出node_modules下的所有package.json，再grep 3.10.1，就看到是谁依赖的了
