推荐答案

• 您如何启动Node?您永远不必关闭终端窗口.至少，您应该能够键入 ctrl C 停止它，然后按向上箭头将node命令从命令历史记录中移回，或者键入命令!!，表示我运行的最后一个命令行"，然后按回车键.

  • How are you starting Node? You should never have to close your terminal window. At the very least, you should be able to type ctrlC to stop it, then press the up arrow to bring the node command back from your command history, or type the command !!, which means "the last command line I ran", and hit the return key.

    或者，使用 node-dev .当文件在与节点脚本相同的目录中更改时，它将自动重新启动节点.您可以使用 npm 进行安装.然后，运行node-dev而不是node:

    Or, use node-dev. It automatically restarts node when files change in the same directory as your node script. You can install it with npm. Then, run node-dev instead of node:

    node-dev script.js
