我正在使用 Laravel，我为我的项目找到了一个图表库。这个库（libchart）是php，它使用这个：
include "../libchart/classes/libchart.php";
但是如果我将此代码放在我的视图中，我会收到此错误：
include(../libchart/classes/libchart.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory
我不知道如何在视图中添加代码或在 Laravel 中添加库。
当我下载库时，我有这个：
libchart
->libchart
->demo
然后我粘贴：
myproject
->app
->views
->libchart
->libchart
->demo
并且
include "../libchart/classes/libchart.php";libchart
->libchart
->demo
->LineChartTest.php
编辑：
我试过这个：
我这样做了：
Route::get('pruebaimagen', function() {
include_once(app_path() . '/grafico/libchart/classes/libchart.php');
$data['libchart'] = new Libchart();
return View::make('template', $data);
});在
return View::make('template', $data);Class 'Libchart' not found
感谢 Laravel，您可以利用框架提供的内置功能简化向 Blade 模板添加多个文件的过程。
@include('foldername.filename')
@include('filename')
它们是纯 Laravel 函数。
我终于做到了。 Rahil Wazir 帮助了我，现在我的项目正在运作。
我的路线：
Route::get('pruebaimagen', function() {
include_once(app_path() . '/librerias/libchart/classes/libchart.php');
return View::make('demo.LineChartTest');
});
我的看法：

我在应用程序中添加了一个名为“librerias”的文件夹，并粘贴了该库。 接下来，我去了：
myproject
->composer.json
我添加了这个：“app/librerias”在
autoload
->classmap
然后我用 cmd 运行：composer dump-autoload 并且它起作用了。
不要将您的文件包含在查看文件夹中。
在您的
appanythingFolder现在将您的文件包含在您想要使用它的控制器方法中，如下所示：
public function index() {
include_once(app_path() . '/anythingFolder/libchart/classes/libchart.php');
$data['libchart'] = new Libchart()
return View::make('template', $data);
}
根据需要改进上述代码
