Error:no such file when using fs.outputJsonSync

I have a problem like this. I have created a compile.js file to compile my solidity Contract. In there to handle file I am using the fs-extra module.

This is my compile.js file

const path = require('path');
const solc = require('solc');
const fs = require('fs-extra');

const buildPath = path.resolve(__dirname,'build');
fs.removeSync(buildPath);

const campaignPath= path.resolve(__dirname,'contracts','Campaign.sol');
const source = fs.readFileSync(campaignPath,'utf8');
const output= solc.compile(source,1).contracts;

fs.ensureDirSync(buildPath);

for(let contract in output){
    fs.outputJsonSync(
        path.resolve(buildPath,contract),
        output[contract]
    );
}

It works everything finely, without for each loop. When I compile this file with for loop it gives me an error saying that 

C:\Users\tharindusa\WebstormProjects\Campaign\node_modules\solc\soljson.js:1

Can someone help me to solve this problem? .Thank you

I had run into the same problem while compiling my contracts.The issue with your code is that it tries to create a file named :Campaign which is not allowed in windows.

I used the following code to get around it 

for(let contract in output){
    fs.outputJSONSync(
        path.resolve(buildPath,contract.replace(/:/g,'')+'.json'),
        output[contract]
    );
}

Your filename (:Campaign.json) contains a colon, which is invalid in Windows, where colons are only used with drive letters.
