npm start giving error in node.js
提问by kow
i am totally new to node.js and mongodb. I am using the following link: http://cwbuecheler.com/web/tutorials/2013/node-express-mongo/This procedure worked very fine and got the exact same results. But all of a sudden "npm start" stopped working. I uninstalled every thing and trying to re-install from step 1 given in this tutorial. when i give the command "npm install -g express" i am not getting any list of http 304's and GETS!! . As i ignore and continue the procedure, i give the command npm start , but it does not work. the error displayed is shown below C:\project\nodetest1>npm start
我对 node.js 和 mongodb 完全陌生。我正在使用以下链接：http: //cwbuecheler.com/web/tutorials/2013/node-express-mongo/这个过程工作得很好，得到了完全相同的结果。但突然间“npm start”停止工作。我卸载了所有东西并尝试从本教程中给出的第 1 步重新安装。当我发出“npm install -g express”命令时，我没有得到任何 http 304 和 GETS 列表！！. 当我忽略并继续该过程时，我给出了命令 npm start ，但它不起作用。显示的错误如下所示 C:\project\nodetest1>npm start
> [email protected] start C:\project\nodetest1
> node ./bin/www
npm ERR! [email protected] start: `node ./bin/www`

请帮忙 。提前致谢。

The error suggests that the ./bin/www directory is not found. Paths specified with a dot are relative to the current directory, so your current directory has to be C:/project/nodetest1 for npm startto work in this case.
该错误表明未找到 ./bin/www 目录。用点指定的路径是相对于当前目录的，所以你的当前目录必须是 C:/project/nodetest1npm start才能在这种情况下工作。

There are several issues here.
这里有几个问题。
First, you should upgrade to a newer npm, as the npmthat ships with even the latest version of nodeis out of date. To upgrade npmon Windows, follow the instructions here:
https://github.com/npm/npm/wiki/Troubleshooting#upgrading-on-windows
首先，您应该升级到更新的npm，因为npm即使是最新版本的node也已过时。要npm在 Windows 上升级，请按照此处的说明进行操作：https:
//github.com/npm/npm/wiki/Troubleshooting#upgrading-on-windows
Second, you may need to do some more troubleshooting on your own to find the problem. npm startjust follows the instructions in the package.json. The package.json is telling npmthat startmeans "run node ./bin/www".
其次，您可能需要自己进行更多故障排除才能找到问题。 npm start只需按照package.json. package.json 告诉npm这start意味着“运行节点 ./bin/www”。
What happens when you run that same script from the command line?
当您从命令行运行相同的脚本时会发生什么？
cd C:\project\nodetest1 node ./bin/www
cd C:\project\nodetest1 节点 ./bin/www
Does the file 'bin/www' exist? Is node installed and in your path? These are the issues that you will have to troubleshoot.
文件“bin/www”是否存在？节点是否已安装并在您的路径中？这些是您必须解决的问题。

Delete the node_modules folder.
Run npm installAnd then, re-run your command npm start
删除 node_modules 文件夹。运行npm install然后，重新运行您的命令npm start

The package.json is telling npm that start means "run node ./bin/www".**but packege.json predefined staring script is npm run serve **
package.json 告诉 npm start 的意思是“运行节点 ./bin/www”。**但 packege.json 预定义的凝视脚本是 npm run serve **
please try this one.
请试试这个。
npm run serve
npm 运行服务
"start": "concurrently \"npm run build:watch\" \"npm run serve\""
"start": "concurrently \"npm run build:watch\" \"npm run serve\""
