webman视图模板报错：Class not found

jones 更新于2020-11-17

使用Twig的模板
在浏览器中调用Index.php中的view方法：
ip:8787/index/view,报错如下
Error: Class 'Twig\Environment' not found in /home/webman/webman/support/view/Twig.php:35

使用think-template
Error: Class 'think\Template' not found in /home/webman/webman/support/view/ThinkPHP.php:34

使用Blade
Error: Class 'Jenssegers\Blade\Blade' not found in /home/webman/webman/support/view/Blade.php:35

要composer安装的，你看下文档呢。

三个模板都安装了，安装时wemman仍然在运行，没有报错。以为一切正常，就按文档尝试用三个模板试试。发现上述问题。
暂时解决上述问题的过程如下：
1、停掉webman,再次启动webman,报错如下：

PHP Fatal error:  Uncaught Error: Call to private Dotenv\Repository\Adapter\EnvConstAdapter::__construct() from context 'Illuminate\Support\Env' in /home/webman/webman/vendor/illuminate/support/Env.php:58

2、删除blade
composer remove jenssegers/blade
再次尝试使用think-template/Twig均正常了。
追问：Blade模板的问题怎么解决？

Blade 加一句

composer require vlucas/phpdotenv ^4.0

感谢walkor! 加上之后，启动webman不报错了，但是设置为Blade模板后，貌似不起作用，显示结果为：
hello {{ $name }}
view.html文件内容如下：

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <title>webman</title>

</head>
<body>
hello {{ $name }}
