在 node js 服务器的终端中无法识别 nodemon 命令

我正在从

node server.js 命令正在运行并启动了服务器，但是 nodemon 命令不起作用.

我从 https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens 视频.

我不知道为什么它不起作用我已经尝试了一些安装 nodemon 的命令.

npm install -g nodemonnpm install -g nodemon --savenpm install --save-dev nodemonnpm install -g nodemon@debugnpm install -g --force nodemon

我看过一个链接 我不能全局安装 nodemon，nodemon"无法识别，但我不知道如何设置路径，因为我的项目位置在 D 盘.

我想运行 nodemon server.js.如果有人有想法，请分享.提前致谢.

解决方案

需要全局安装

npm install -g nodemon# 或者如果使用纱线yarn 全局添加 nodemon

然后它就会在路径上可用(我现在看到你已经尝试过了但它没有工作，你的路径可能搞砸了)

如果你想使用本地安装的版本，而不是全局安装，那么你可以在你的 package.json 中创建一个脚本

脚本":{服务":nodemon server.js"},

然后使用

npm run serve

如果使用纱线，则可选

# 在 package.json 中不添加 serve纱线运行 nodemon server.js# 使用 package.json 中的服务脚本纱线运行服务

npm 会先查看本地 node_modules 文件夹，然后再在全局模块中查找命令

I am doing node.js server setup from https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens. I am new in node.js. I am installing npm install nodemon --save. But when I am run the server with this nodemon server.js.
In the terminal showing:

nodemon is not recognized as internal or external command, operable program or batch file

node server.js command is working and started the server, But nodemon command is not working.

I am set up the node js server from https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens video.

I don't know why it is not working I have tried some command for the install nodemon.

npm install -g nodemon 
npm install -g nodemon --save 
npm install --save-dev nodemon 
npm install -g nodemon@debug 

npm install -g --force nodemon

I have seen one link I can´t install nodemon globally, "nodemon" not recognized, But I don't know how to set the path because of my project location in D drive.

I want to run nodemon server.js. If anybody has an idea please share. Thanks in advance.

解决方案

You need to install it globally

npm install -g nodemon
# or if using yarn
yarn global add nodemon

And then it will be available on the path (I see now that you have tried this and it didn't work, your path may be messed up)

If you want to use the locally installed version, rather than installing globally then you can create a script in your package.json

"scripts": {
    "serve": "nodemon server.js"
  },

and then use

npm run serve

optionally if using yarn

# without adding serve in package.json
yarn run nodemon server.js
# with serve script in package.json
yarn run serve

npm will then look in your local node_modules folder before looking for the command in your global modules
