这是Windows 10的一种方法(可能适用于7)，它改变了cmd, npm终端本身的配色方案(主题)，而不仅仅是特定应用程序的控制台输出。

我找到了一个Windows插件——颜色工具，它应该是在Windows保护伞下开发的。在链接中有描述。

我将colortool目录添加到系统环境路径变量中，现在每当我启动终端(NodeJs命令提示符，cmd)时，它都可用。

If you are using Windows CMD then go to the terminal Properties/Colors (CMD top left) and then redefine the RGB value of the offensive color. In my case I believe it's the fifth color square from the left, which I changed to (222,222,222). It does not matter if the currently selected radio button shows Screen Text or Screen Background as you just redefine that specific "system" color. Once you changed the color don't forget to select back the preferred color for the background or text before clicking OK.

更改后，所有来自Node(在我的情况下是Ember)的红色消息都清晰可见。

我重载了控制台方法。

var colors={
Reset: "\x1b[0m",
Red: "\x1b[31m",
Green: "\x1b[32m",
Yellow: "\x1b[33m"
};

var infoLog = console.info;
var logLog = console.log;
var errorLog = console.error;
var warnLog = console.warn;

console.info= function(args)
{
    var copyArgs = Array.prototype.slice.call(arguments);
    copyArgs.unshift(colors.Green);
    copyArgs.push(colors.Reset);
    infoLog.apply(null,copyArgs);
};

console.warn= function(args)
{
    var copyArgs = Array.prototype.slice.call(arguments);
    copyArgs.unshift(colors.Yellow);
    copyArgs.push(colors.Reset);
    warnLog.apply(null,copyArgs);
};
console.error= function(args)
{
    var copyArgs = Array.prototype.slice.call(arguments);
    copyArgs.unshift(colors.Red);
    copyArgs.push(colors.Reset);
    errorLog.apply(null,copyArgs);
};

// examples
console.info("Numeros",1,2,3);
console.warn("pares",2,4,6);
console.error("reiniciandooo");

输出为。

我在我的snippet目录中创建了一个名为styles.js的文件，我认为它可以帮助任何想要导入单个文件的人。

这是对color.js的styles.js文件的一个小修改，帮助了我很多。

以下是该文件的内容:

// Original: https://github.com/Marak/colors.js/blob/master/lib/styles.js

const styleCodes = {
    // Reset all styles.
    reset: [0, 0],
    
    // Text styles.
    bold: [1, 22],
    dim: [2, 22],
    italic: [3, 23],
    underline: [4, 24],
    inverse: [7, 27],
    hidden: [8, 28],
    strikethrough: [9, 29],
    
    // Foregound classic colours.
    fgBlack: [30, 39],
    fgRed: [31, 39],
    fgGreen: [32, 39],
    fgYellow: [33, 39],
    fgBlue: [34, 39],
    fgMagenta: [35, 39],
    fgCyan: [36, 39],
    fgWhite: [37, 39],
    fgGray: [90, 39],
    
    // Foreground bright colours.
    fgBrightRed: [91, 39],
    fgBrightGreen: [92, 39],
    fgBrightYellow: [93, 39],
    fgBrightBlue: [94, 39],
    fgBrightMagenta: [95, 39],
    fgBrightCyan: [96, 39],
    fgBrightWhite: [97, 39],

    // Background basic colours.
    bgBlack: [40, 49],
    bgRed: [41, 49],
    bgGreen: [42, 49],
    bgYellow: [43, 49],
    bgBlue: [44, 49],
    bgMagenta: [45, 49],
    bgCyan: [46, 49],
    bgWhite: [47, 49],
    bgGray: [100, 49],
    bgGrey: [100, 49],
    
    // Background bright colours.
    bgBrightRed: [101, 49],
    bgBrightGreen: [102, 49],
    bgBrightYellow: [103, 49],
    bgBrightBlue: [104, 49],
    bgBrightMagenta: [105, 49],
    bgBrightCyan: [106, 49],
    bgBrightWhite: [107, 49],
};

// This object will contain the string representation for all style codes.
const styles = {};

// Loop over all the style codes and assign them to the `styles` object.
// 
// The a `styleCode` in the `styleCodes` object consists of two numbers:
// Index 0: The opening style code (In HTML this can be the opening <b> tag).
// Index 1: The closing style code (In HTML this can be the closing </b> tag).
for (let styleCode of Object.keys(styleCodes)) {
    styles[styleCode] = {
        open: `\x1B[${styleCodes[styleCode][0]}m`,
        close: `\x1B[${styleCodes[styleCode][1]}m`,
    };
}

module.exports = styles;

其实用起来很简单。

const styles = require("/path/to/styles.js");

// Let's say we've got an error:
const errorOpen = styles.bold.open + styles.bgRed.open + styles.fgWhite.open;
const errorClose = styles.reset.close; // Close everything
console.log(errorOpen, "ERROR", errorClose, ": Missing semicolon at line 9.");

我发现上面的答案(https://stackoverflow.com/a/41407246/4808079)非常有用，但不完整。如果你只想给某样东西上色一次，我想这没问题，但我认为以可运行的函数形式共享它更适用于现实生活中的用例。

const Color = {
  Reset: "\x1b[0m",
  Bright: "\x1b[1m",
  Dim: "\x1b[2m",
  Underscore: "\x1b[4m",
  Blink: "\x1b[5m",
  Reverse: "\x1b[7m",
  Hidden: "\x1b[8m",
  
  FgBlack: "\x1b[30m",
  FgRed: "\x1b[31m",
  FgGreen: "\x1b[32m",
  FgYellow: "\x1b[33m",
  FgBlue: "\x1b[34m",
  FgMagenta: "\x1b[35m",
  FgCyan: "\x1b[36m",
  FgWhite: "\x1b[37m",
  FgGray: "\x1b[90m",
  
  BgBlack: "\x1b[40m",
  BgRed: "\x1b[41m",
  BgGreen: "\x1b[42m",
  BgYellow: "\x1b[43m",
  BgBlue: "\x1b[44m",
  BgMagenta: "\x1b[45m",
  BgCyan: "\x1b[46m",
  BgWhite: "\x1b[47m"
  BgGray: "\x1b[100m",
}

function colorString(color, string) {
  return `${color}${string}${Color.Reset}`;
}

function colorLog(color, ...args) {
  console.log(...args.map(
   (it) => typeof it === "string" ? colorString(color, string) : it
  ));
}

像这样使用它:

colorLog(Color.FgYellow, "Some Yellow text to console log", { someObj: true });

console.log([
  colorString(Color.FgRed, "red"),
  colorString(Color.FgGreen, "green"),
  colorString(Color.FgBlue, "blue"),
].join(", "));

    Underscore : "\x1b[4m",
    Blink : "\x1b[5m",

    BgMagenta : "\x1b[45m",
    BgCyan : "\x1b[46m",
    BgWhite : "\x1b[47m",
};

module.exports = () => {
    Object.keys(colors).forEach(key => {
        console['log' + key] = (strg) => {
            if(typeof strg === 'object') strg = JSON.stringify(strg, null, 4);
            return console.log(colors[key]+strg+'\x1b[0m');
        }
    });
}

app.js

require('./logger')();

然后这样使用它:

console.logBgGreen(" grüner Hintergrund ")
