節點READFILE路徑必須是一個字符串

Question

的文檔fs.readFileSync是

file <String> | <Buffer> | <Integer> filename or file descriptor 

但

require('fs').readFile(0); 

導致給定一個（ 「整數」）文件描述符，如何錯誤

TypeError: path must be a string 
at TypeError (native) 
at Object.fs.readFile (fs.js:250:11) 
at repl:1:15 
at REPLServer.defaultEval (repl.js:252:27) 
at bound (domain.js:287:14) 
at REPLServer.runBound [as eval] (domain.js:300:12)

at emitOne (events.js:82:20) 
at REPLServer.emit (events.js:169:7) 
at REPLServer.Interface._onLine (readline.js:211:10) 

我讀過它嗎？
