Question

我想运行build命令，但收到错误消息：

TypeError：Path必须是字符串。收到undefined。

你们有什么想法吗？感谢。

gulp.task('build', function () {
    browserify("./src/components/source.js")
        .transform("babelify", {presets: ["es2015", "react"]})
        .bundle()
        .pipe(gulp.dest(path.resolve(__dirname, './src/app.js')));
});

以下是tracestack详细信息：
