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:

"Inherit" means [0, 1, 2] or [process.stdin, process.stdout, process.stderr].

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>

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>

note that the code use es6

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.

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.
