gulp:"TypeError:打印不是函数"； [英] gulp : "TypeError: print is not a function"

问题描述

我正在尝试使用gulp在目录中构建Semantic-UI，但是出现这些错误:

I am trying to build Semantic-UI with gulp in a directory, but I get having these errors :

如果我检查javascript.js文件，则正确加载了gulp-print:

If I check javascript.js file, gulp-print is correctly loaded :

var print = require('gulp-print');

并使用(下面的第8行):

and used (8th line below) :

  // copy source javascript
  gulp.src(source.definitions + '/**/' + globs.components + '.js')
    .pipe(plumber())
    .pipe(flatten())
    .pipe(replace(comments.license.in, comments.license.out))
    .pipe(gulp.dest(output.uncompressed))
    .pipe(gulpif(config.hasPermission, chmod(config.permission)))
    .pipe(print(log.created))
    .pipe(uglify(settings.uglify))
    .pipe(rename(settings.rename.minJS))
    .pipe(gulp.dest(output.compressed))
    .pipe(gulpif(config.hasPermission, chmod(config.permission)))
    .pipe(print(log.created))
    .on('end', function() {
      gulp.start('package compressed js');
      gulp.start('package uncompressed js');
      callback();
    })
  ;

Gulp版本:

[10:42:25] CLI version 3.9.1
[10:42:25] Local version 3.9.1

有人对这个问题有想法吗? 谢谢！

Does anybody has thoughts on this problem? Thank you!

推荐答案

gulpPrint函数是默认导出，因此，在导入gulp依赖项时需要添加一些代码.替换:

gulpPrint function is default export, therefore, I need to add a bit of code while importing gulp dependencies. Replace :

var print        = require('gulp-print');

作者:

var print        = require('gulp-print').default;
// usage
print();

所以gulpPrint();函数重命名为print();

so the gulpPrint(); function is renamed print();

或也可以通过以下方式使用:

or can also be used in the following way:

var print = require('gulp-print');
// usage
print.default()

例如，如有疑问，请使用console.log(print)转储变量内容.如果您是像我这样的初学者，则对理解其背后的逻辑将有很大帮助.

In case of doubt, dump variable contents with console.log(print), for instance. It will help a lot to understand the logic behind it if you are a beginner like me.
