“serve -s build”返回“serve: command not found”

Question

我克隆了一個react項目，大概是在純Windows下開發的，到我的windows的WSL中。

看來，要在 IE 和 Edge 中正確啟動 React 應用程序，我們需要構建項目並提供服務。 所以我做了yarn add react-scripts 、 yarn install和yarn build ，這給了我：

The build folder is ready to be deployed.
You may serve it with a static server:

  yarn global add serve
  serve -s build

Find out more about deployment here:

  bit.ly/CRA-deploy

然后，

$ yarn global add serve
yarn global v1.22.0
[1/4] Resolving packages...
[2/4] Fetching packages...
[3/4] Linking dependencies...
[4/4] Building fresh packages...
success Installed "serve@11.3.0" with binaries:
      - serve
Done in 1.49s.

$ serve -s build
No command 'serve' found, did you mean:
 Command 'pserve' from package 'python-pyramid' (universe)
 Command 'server' from package 'rsplib-legacy-wrappers' (universe)
serve: command not found

這是package.json 。 有誰知道問題出在哪里？

Answer 1

在 package.json 你可以添加一些步驟

 "scripts": {
...
    "start:prod": "serve -s dist -l 3000"
...
  }

之后在本地運行

npm run-script start:prod

Answer 2

您需要使用與節點版本兼容的版本全局添加服務。
