Try this instead:

<pre><code>var spawn = require('child_process').spawn
 , command = 'C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\MSBuild c:\\test.sln'
 , cmd = spawn('cmd', ['/s', '/c', command], { customFds: [0,1,2] });

cmd.on('exit', function(code){
 console.log(code);
});
</code></pre>

Note that I'm not positive whether or not <code>customFds</code> works on Windows. I know that it's old deprecated functionality doesn't work, but when only passing <code>[0,1,2]</code> as the fd's, I think there is a special case for that.

I've been doing <a href="https://github.com/TooTallNate/node-weak/blob/1cf1ff4909ddf959218501ecd6ad58d53766de04/build.js#L13-15" rel="noreferrer">something similar here</a>, but I've only ran that command on Unix machines. So let me know if that works on Windows.

There are new 'stdio' option for child_process.spawn(). Try following:

crossplatform solution that worked for me was to use both <code>shell: true</code> and <code>stdio: 'inherit'</code>:

<pre><code>const spawn = require('child_process').spawn;

spawn('node', ['./child.js'], { shell: true, stdio: 'inherit' });
</code></pre>

blocks|key|759506|text|这不能解决根本问题(缺乏适当的TTY流)，但它应该有助于绕过它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|759507|如果您正在运行的子进程使用像粉笔一样的支持颜色(https://www.npmjs.com/package/supports-color)，那么您可以将环境变量FORCE_COLOR设置为任何值，它将跳过其余的检查。这将允许您继续使用管道(并捕获/修改返回的数据)，这与inherit修复程序不同。|offset|length|style|CODE|759508|还有一个node-pty+(https://www.npmjs.com/package/node-pty)模块，它为.spawn提供了传递可能是更全面的答案的pty+(伪tty)的能力。我还没有试过它，我不确定它是不是跨平台的。|759509|entityMap|0|LINK|mutability|MUTABLE|url|https://www.npmjs.com/package/supports-color|1|https://www.npmjs.com/package/node-pty^0|0|28|B|3R|7|O|18|0|0|1M|6|E|12|1|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@$D|V|E|W|F|G]|$D|X|E|Y|F|G]]|9|@$D|Z|E|10|1|11]]|A|$]]|$1|H|3|I|5|6|7|12|8|@$D|13|E|14|F|G]]|9|@$D|15|E|16|1|17]]|A|$]]|$1|J|3|-4|5|6|7|18|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q]]|R|$5|M|N|O|A|$P|S]]]]

This doesn't fix the underlying issue (lack of a proper TTY stream) but it should help get around it.

If the sub-process you're running uses supports-color (<a href="https://www.npmjs.com/package/supports-color" rel="noreferrer">https://www.npmjs.com/package/supports-color</a>) like chalk, then you can set an environmental variable <code>FORCE_COLOR</code> to any value and it will skip the rest of the checks. This will allow you to continue to use pipes (and capture/modify the returned data) unlike the <code>inherit</code> fix.

There is also a node-pty (<a href="https://www.npmjs.com/package/node-pty" rel="noreferrer">https://www.npmjs.com/package/node-pty</a>) module that provides a <code>.spawn</code> with the ability to pass a pty (pseudo tty) that may be a more holistic answer. I haven't played with it yet, and I'm not sure if it's cross platform or not.

If you want to either keep the color or add some notation for the output, you can try the code below:

<pre><code>var spawn = require('child_process').spawn,
var stream = require('stream');
cmd = spawn('cmd', ['/s', '/c', 'C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\MSBuild c:\\test.sln'], { stdio: [process.stdin, process.stdout, 'pipe'] });
var customStream = new stream.Writable();
customStream._write = function (data, ...argv) {
 console.log('your notation');
 process.stderr._write(data, ...argv);
 };
cmd.stderr.pipe(customStream);
</code></pre>

blocks|key|542948|text|我已经尝试了上面的许多选项，但它们都不起作用。对于npm+(可能还有node)命令，这是有效的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|542949|const+ps+=+_spawn('npm',+['outdated',+'--color=always'],+{+stdio:+'pipe'});

I have tried many options above, and they did not work. For npm (and probably node) commands, this works:
<pre><code>const ps = _spawn('npm', ['outdated', '--color=always'], { stdio: 'pipe'});
ps.stdout.pipe(process.stdout);
// Then, you can also ps.stdout.on('data',...) for further processing
</code></pre>
The trick is the <code>--color=always</code> (using Mac OSX with zsh). I did not need to do the FORCE_COLOR.
However, that does not work for all commands, for example <code>ls</code> does not seem to accept this argument.

I'm trying to execute a windows command through cmd.exe in node.js using child_process.spawn. It executes correctly, but only displays in default text color. How do I preserver the color. Is it possible?

<pre><code>var spawn = require('child_process').spawn,
 cmd = spawn('cmd', ['/s', '/c', 'C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\MSBuild c:\\test.sln']);

cmd.stdout.on('data', function(data){
 process.stdout.write(data);
});

cmd.stderr.on('data', function(data){
 process.stderr.write(data);
});

cmd.on('exit', function(code){
 console.log(code);
});
</code></pre>

When executing via node, the color is not preserved.

When executing via cmd.exe directly, the color is present. (This is the expected behavior). How do I get this behvior when executing via node.
