Laravel 文件上传错误：缺少临时文件夹

Question

我正在使用 Ubuntu 16.04、ISPConfig 和 Laravel 运行服务器。对于测试，我得到了一个具有基本相同设置的本地测试服务器。测试服务器有另一个域，没有 https。我已经在我的测试服务器上集成了 Laravel 的文件上传。我使用http://image.intervention.io/，它在我的测试服务器上运行良好。

Liveserver 失败。无法传递“hasFile”函数。

表格：

<div class="form-group">
  <div class="row">
    <div class="col-md-10 col-md-offset-1">
      <img src="/uploads/avatars/{{$user->avatar}}" style="width:150px; 
       height:150px; float:left; border-radius:50%; margin-
       right:25px;">
      <form enctype="multipart/form-data" 
       action="/account/edit/upload_avatar" method="post">
        <input type="file" name="avatar">
        {{ csrf_field() }}
        <input type="submit" class="pull-right btn btn-sm btn-primary">
      </form>
    </div>
  </div>
</div>

控制器：

 public function upload_avatar(Request $request)
 {
    dd($request);

    if($request->hasFile('avatar')) {
      $avatar = $request->file('avatar');
      $filename = time() . '.' . $avatar->getClientOriginalExtension();
      Image::make($avatar)->resize(300, 300)->save( 
      public_path('uploads/avatars/' . $filename));

      $user = Sentinel::getUser();
      $user->avatar = $filename;
      $user->save();

      return back();
    }
  }

错误：6 UPLOAD_ERR_NO_TMP_DIR

值：6；缺少一个临时文件夹。在 PHP 4.3.10 和 PHP 中引入

Php.ini 的文件上传设置与测试服务器相同。 这是来自我的 php.ini：

    ;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Whether to allow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default 
 if not
; specified).
; http://php.net/upload-tmp-dir
;upload_tmp_dir =

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 2M

; Maximum number of files that can be uploaded via a single request
max_file_uploads = 20

没有 if(hasFile) iIget 如下：

NotReadableException
Unsupported image type. GD driver is only able to decode JPG, PNG, GIF 
or WebP files.

我已经检查了整个项目的文件权限，甚至在文件目标上使用 777 进行了尝试。

我知道了，谢谢！现在解决了。 Tmp 文件夹手错权限。
