Laravel-无法运行工匠命令

Question

今天，我打开了Laravel 5.4的一个旧项目（我认为），我想对其进行一些编辑，以便将其全部保存，但是在运行任何artisan命令时，我收到了写在控制台（cmd）上的巨大错误。

<?php
/*
|--------------------------------------------------------------------------
| Create The Application
|--------------------------------------------------------------------------
|
| The first thing we will do is create a new Laravel application instance
| which serves as the "glue" for all the components of Laravel, and is
| the IoC container for the system binding all of the various parts.
|
*/

$app = new Illuminate\Foundation\Application(
    realpath(__DIR__.'/../')
);

/*
|--------------------------------------------------------------------------
| Bind Important Interfaces
|--------------------------------------------------------------------------
|
| Next, we need to bind some important interfaces into the container so
| we will be able to resolve them when needed. The kernels serve the
| incoming requests to this application from both the web and CLI.
|
*/

$app->singleton(
    Illuminate\Contracts\Http\Kernel::class,
    App\Http\Kernel::class
);

$app->singleton(
    Illuminate\Contracts\Console\Kernel::class,
    App\Console\Kernel::class
);

$app->singleton(
    Illuminate\Contracts\Debug\ExceptionHandler::class,
    App\Exceptions\Handler::class
);

/*
|--------------------------------------------------------------------------
| Return The Application
|--------------------------------------------------------------------------
|
| This script returns the application instance. The instance is given to
| the calling script so we can separate the building of the instances
| from the actual running of the application and sending responses.
|
*/

return $app;
PHP Fatal error:  Uncaught Error: Call to a member function make() on integer in C:\Users\admin\Desktop\mywebsite\website\artisan:31
Stack trace:
#0 {main}
  thrown in C:\Users\admin\Desktop\mywebsite\website\artisan on line 31

看起来像一个php文件的整个内容，然后下面的错误

PHP Fatal error:  Uncaught Error: Call to a member function make() on integer in C:\Users\admin\Desktop\mywebsite\website\artisan:31
    Stack trace:
    #0 {main}
      thrown in C:\Users\admin\Desktop\mywebsite\website\artisan on line 31

Answer 1

我只是遇到这种错误，然后我发现我的某些文件特别是bootstrap / app.php损坏了，为什么它显示了一些奇怪的字符。

Answer 2

OP进入php聊天室寻求帮助。 经过一些调试后，发现问题是由于缺少.env文件，导致应用程序无法正确构建。

对于OP，可以通过将_env重命名为.env并确保将APP_KEY设置为有效的长度和内容来解决此问题。
