場景重現

npm install --verbose 安裝依賴的時,出現以下警告vue

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
npm verb notsup SKIPPING OPTIONAL DEPENDENCY: Valid OS:    darwin
npm verb notsup SKIPPING OPTIONAL DEPENDENCY: Valid Arch:  any
npm verb notsup SKIPPING OPTIONAL DEPENDENCY: Actual OS:   win32
npm verb notsup SKIPPING OPTIONAL DEPENDENCY: Actual Arch: x64

釋疑

這不是什麼真的有問題,只是你的某些包依賴fsevents包,而fsevents包是MacOS系統下,在Windows/Linux下會提示警告,但不會安裝.node

解決辦法

可是強迫症患者表示不能接受,換個角度看釋疑,意味着fsevents在MacOS下是必須的,而在Windows/Linux下是可選的.ios

那麼咱們能夠經過package.json的optionalDependencies來規避警告,而後npm install --no-optional --verbose不安裝可選項便可.vue-router

參考以下:vuex

{
    "dependencies": {
        "axios": "^0.18.0",
        "echarts": "^4.2.0-rc.2",
        "element-ui": "^2.4.11",
        "screenfull": "^3.3.3",
        "vue": "^2.5.17",
        "vue-router": "^3.0.1",
        "vuex": "^3.0.1"
    },
    "devDependencies": {
        "@vue/cli-plugin-babel": "^3.0.5",
        "@vue/cli-service": "^3.0.5",
        "less": "^3.0.4",
        "less-loader": "^4.1.0",
        "vue-template-compiler": "^2.5.17"
    },
    "optionalDependencies": {
        "fsevents": "*"
    }
}
