执行npm run dev报错。具体描述如下：
npm script定义是：
“scripts”: {
“dev:build”: “tsc -w”,
“dev:start”: “nodemon node ./dist/crowler.js”,
“dev”: “concurrently npm:dev:"
},
“nodemonConfig”: {
“ignore”: [
"data/”
]
},
我和视频中不一样的是：删掉了dist目录和data目录下的course.json，执行npm run dev后报错：
[dev:start] [nodemon] starting node node ./dist/crowler.js index.js
[dev:start] internal/modules/cjs/loader.js:797
