我正在尝试使用npm start
命令,但是我的 package.json 中没有正确的“开始” 脚本。谁能告诉我正确的添加方式?
我尝试在 package.json 中的脚本中添加“ start”:“ node server.js” ,但这会引发错误:
> node server.js
internal/modules/cjs/loader.js:589
throw err;
^

因此找不到 server.js 文件。谁能详细说明我应该在哪个文件中添加到“开始”脚本中? Package.json :
{
"name": "aristophanes",
"version": "1.0.0",
"description": "",
"main": ".eslintrc.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node server.js"
},
"author": "",
"license": "ISC"
}
答案 0 :(得分:0)
尝试在package.json中更改"main": "server.js"
编辑:您必须将文件名定义为main
,其中包含您的server.listen
回调。另外,您可以从node [your-server-file].js
开始运行。如果您的文件名为index.js
,节点会自动找到它,则不需要main
部分。
