【问题描述】：

我正在尝试使用 Gulp 将我的 CSS 转换为 PostCss。

当我将 cssnext 插件添加到 PostCss 时，我收到以下错误：

Unknown error from PostCSS plugin. Your current PostCSS version is 6.0.19, but postcss-import uses 4.1.16. Perhaps this is the source of the error below.

这是我的gulpfile.js：

const gulp = require('gulp');
const postcss = require('gulp-postcss');
const concat = require('gulp-concat');

gulp.task('styles', function() 

    const postCssPlugins = [
        require('cssnext')()
    ];

    gulp.src('src/css/*.css')
        .pipe(postcss(postCssPlugins))
        .pipe(concat('style.css'))
        .pipe(gulp.dest('.'));
);

完整的堆栈跟踪：

events.js:183
  throw er; // Unhandled 'error' event
  ^
TypeError: styles.eachAtRule is not a function
at parseStyles (C:\gulp-test\node_modules\cssnext\node_modules\postcss-import\index.js:134:10)

at LazyResult.then (C:\gulp-test\node_modules\postcss\lib\lazy-result.js:134:21)
at process._tickCallback (internal/process/next_tick.js:188:7)

据我所知，postcss-import 包是cssnext的一个依赖。那我该怎么办？

【参考方案1】：

我找到了答案：

根据cssnext 的网站，cssnext 包（我用的）已经死了。与 PostCSS 一起使用的新包是 postcss-cssnext:

const postCssPlugins = [
    require('postcss-cssnext')()
];
