在使用yarn在devDependency中构建具有Webpack作为package.json的Node项目时，出现了一个错误（实际上是一个信息）。我使用Ubuntu 19.04：

info fsevents@1.2.9: The platform "linux" is incompatible with this module.
info "fsevents@1.2.9" is an optional dependency and failed compatibility check. Excluding it from installation.

package.json：

{
    "name": "my-app","version": "1.0.0","description": "A new app.","main": "index.js","author": "John Doe","license": "MIT","dependencies": {
        "@types/react": "16.9.11","@types/react-dom": "16.9.4","@types/react-router-dom": "5.1.2","bootstrap": "4.3.1","jquery": "3.4.1","popper.js": "1.16.0","react": "16.11.0","react-dom": "16.11.0","react-router-dom": "5.1.2"
    },"devDependencies": {
        "typescript": "3.7.2","webpack": "4.41.2"
    },"scripts": {
        "develop": "webpack-dev-server --mode development --open --port 8081 --host 0.0.0.0 --config webpack.dev.config.js","build": "webpack --mode production --config webpack.prod.config.js"
    }
}

如果我再次点击yarn，info不会再次出现。

这到底是什么意思？有缺少的零件吗？可以忽略吗？
