我需要实现一个判断编译是否通过的程序。然后就写了下面的代码。
var execSync = require('child_process').execSync;
var fs = require('fs');
var cmd = 'g++ program.cpp -o program -O2';
console.log(cmd);
execSync(cmd);
if (! (fs.existsSync('program')))
console.log('Compile Fail');
else
console.log('Compile Success');
如果编译成功是没有问题的,但是编译失败的话,execSync会抛出一个错误,官网也有这样的说明:
If the process times out, or has a non-zero exit code, this method will throw. The Error object will contain the entire result from child_process.spawnSync
但是我不想它抛出错误,而是继续执行console.log('Compile Fail');
这一语句,应该怎么办??
