Question

我收到此错误

我运行此任务时终端中的

var gulp = require('gulp');
var jshint = require('gulp-jshint');
var stylish = require('jshint-stylish');

gulp.task('lint', function () {
    return gulp.src('public/**/*.js')
            .pipe(jshint(['.jshintignore', '.jshintrc']))
            .pipe(jshint.reporter(stylish));
});

这是我的.jshintrc文件

关于为什么会发生这种情况的任何建议？

狂野的猜测，但也许你的文件是用gulp无法识别的BOM code保存的。

尝试使用您喜欢的编辑器保存没有BOM代码的文件，例如vim：

vim +'set nobomb | x' /path/to/files

或者可能是json中的结尾.jshintrc：

 "predef"        : [  // Custom globals.
     //"exampleVar",
     //"anotherCoolGlobal",
     //"iLoveDouglas"
 ],json
// ^ What is this?

为什么我在运行gulp linter任务后得到此错误`line 0 col 0 Bad option：'0'`？
