我正在尝试使用命令node app.js
运行 app.js 文件,控制台将返回此错误:
buffer.js:200
throw new ERR_INVALID_ARG_TYPE(
^
TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined

at startup (internal/bootstrap/node.js:308:19)
at bootstrapNodeJSCore (internal/bootstrap/node.js:878:3)
有人能启发我如何解决此错误吗?显然这与不正确的参数有关,但我真的不知道要去哪里。
答案 0 :(得分:0)
您应该查看app.js,第14行,第28行,
