node.js - create-react-app 'npm start' 不起作用，即使是新建的应用程序。 chokidar Node 模块内部抛出的错误

Question

在使用“create-react-app”新建的应用程序上使用“npm start test_app”时遇到此错误。这个问题也出现在我之前使用 create-react-app 创建的项目中。 我尝试将 Node 版本更新为 v8.9.1，将 npm 版本更新为 5.5.1。问题仍然存在。

test_app@0.1.0 start /home/user/test_app react-scripts start

Starting the development server...

我在使用 create-react-app 创建应用程序后运行“npm install”时收到以下警告(这可能是相关的，因为抛出错误的 chokidar 是 fs.watch 的包装器):

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.2 (node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

Answer 1

答案是更新 Node 版本。

nvm install lts/*

我遇到了同样的问题，自从上一个项目以来我一直在使用 Node 8(现在是 10)，这是因为弃用问题，很遗憾，但是旧的 js 函数已被完全删除
