const chalk = require('chalk');
console.log(chalk.green('项目创建成功'));
console.log(chalk.red('项目创建失败'));除了给打印信息加上颜色之外，还可以使用 log-symbols 在信息前面加上 √ 或 × 等的图标
const chalk = require('chalk');
const symbols = require('log-symbols');
console.log(symbols.success, chalk.green('项目创建成功'));
console.log(symbols.error, chalk.red('项目创建失败'));
