无法从ionic Cli 4.1.2构建离子版本1

Question

我有一个旧的Ionic版本1项目，和一个Windows 7机器，它是格式化的。

安装Ionic Cli 4.1.2之后，我尝试构建这个Ionic版本1，项目，但它给出了错误消息：

无法运行sass任务: gulpfile.js中缺少

完全错误消息：

ionic-v1 build

如何编译离子版本1项目？

Answer 1

试着重新安装乙烯基fs

$ rm -rf node_modules/vinyl-fs
$ npm install vinyl-fs

同一问题

var gulp = require('gulp');
var sass = require('gulp-sass');
var cleanCss = require('gulp-clean-css');
var rename = require('gulp-rename');

var paths = {
  sass: ['./scss/**/*.scss']
};

gulp.task('default', ['sass']);

gulp.task('sass', function(done) {
  gulp.src('./scss/ionic.app.scss')
    .pipe(sass())
    .on('error', sass.logError)
    .pipe(gulp.dest('./www/css/'))
    .pipe(cleanCss({
      keepSpecialComments: 0
    }))
    .pipe(rename({ extname: '.min.css' }))
    .pipe(gulp.dest('./www/css/'))
    .on('end', done);
});

gulp.task('watch', ['sass'], function() {
  gulp.watch(paths.sass, ['sass']);
});
