如何解决npm安装在非MAC操作系统上抛出fsevents警告？

npm install命令正在引发以下警告 –

 npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.2 (node_modules\rea ct-scripts\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@ 1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"} ) npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\ch okidar\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@ 1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"} ) 

警告显然是导致我们的jenkins工作标记失败，所以我们只是试图摆脱相同的。

我已经检查了这个https://stackoverflow.com/a/42938398/351903但是，不同于在那里提到的，我没有任何/ node_modules / fserrors在我的设置。 另外，我的package.json不包含fserrors。 以下是我的package.json –

 { "name": "mvc-panel", "version": "0.1.0", "private": true, "dependencies": { "bootstrap": "^3.3.7", "jquery": "^3.2.1", "material-ui": "^0.18.3", "qs": "^6.4.0", "react": "^15.5.4", "react-alert": "^2.1.2", "react-bootstrap-table": "^3.4.1", "react-dom": "^15.5.4", "react-loader": "^2.4.2", "react-router-dom": "^4.1.1", "react-tap-event-plugin": "^2.0.1", "serve": "^6.0.0" }, "devDependencies": { "datatables.net": "^1.10.15", "jquery": "^3.2.1", "react-scripts": "^1.0.7" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test --env=jsdom", "eject": "react-scripts eject" } } 

我可以在node_modules\react-scripts\package.json的react-scripts（在我的package.json的node_modules\react-scripts\package.json下定义）的package.json中node_modules\react-scripts\package.json –

更新

我试着运行npm install命令并获得早期命令的退出状态。 尽pipe有警告，但表示0意味着成功。 所以，看起来jenkins的工作不应该因此而卡住。 但是，我们仍然试图find摆脱这个警告的方法，因为它与我们的操作系统无关。

Answer 1

在mac和其他linux系统中， fsevents的处理fsevents是不同的。 Linux系统忽略fsevents而mac安装它。 由于上述错误消息指出fsevents是可选的，并且在安装过程中被跳过。

你可以在linux系统下运行npm install --no-optional命令来避免以上警告。
