MediaWiki - 可视化编辑器扩展：（卷曲错误：28）已达到超时

Question

我在尝试借助可视化编辑器编辑页面时显示以下错误（以前还没有工作）：

Error loading data from server: apierror-visualeditor-docserver-http-error: (curl error: 28) Timeout was reached. Would you like to retry?

我认为以上是端口问题，因为我执行命令时出于某种奇怪的原因无法访问端口 8142：

curl -L http://40.68.204.191:8142

并收到以下回复：

curl: (7) Failed to connect to 40.68.204.191 port 8142: Connection timed out

我已通过执行以下操作安装了可视化编辑器扩展：

1. 从ExtensionDistributor 页面下载可视化编辑器。拿到代码后，我把它保存到我wiki的/opt/bitnami/apps/mediawiki/htdocs/extensions/VisualEditor目录中。

   我已经安装了 1.32 版（最新的稳定版 MediaWiki）

2. 我已按照安装说明安装了 Parsoid，可在此处找到：https://www.mediawiki.org/wiki/Parsoid/Setup

3. 我已将以下代码添加到我的 LocalSettings.php 文件中：

   wfLoadExtension( 'VisualEditor' );
   

   和

   ##### VisualEditor Config #####
   
   // Enable by default for everybody
   
   $wgDefaultUserOptions['visualeditor-enable'] = 1;
   
   // Optional: Set VisualEditor as the default for anonymous users
   
   // otherwise they will have to switch to VE
   
   $wgDefaultUserOptions['visualeditor-editor'] = "visualeditor";
   
   // Don't allow users to disable it
   
   $wgHiddenPrefs[] = 'visualeditor-enable';
   
   // OPTIONAL: Enable VisualEditor's experimental code features
   
   #$wgDefaultUserOptions['visualeditor-enable-experimental'] = 1;
   
   $wgVirtualRestConfig['modules']['parsoid'] = array(
   
       // URL to the Parsoid instance
   
       // Use port 8142 if you use the Debian package
   
       'url' => 'http://40.68.204.191:8142',
   
       // Parsoid "domain", see below (optional)
   
       'domain' => '40.68.204.191',
   
       // Parsoid "prefix", see below (optional)
   
       'prefix' => '40.68.204.191'
   
   );
   

4. 我已更改 config.yaml 文件（用于 Parsoid 配置）中的 2 行代码，该文件可在我的虚拟机上的“/etc/mediawiki/parsoid”文件夹中找到：

   # Configure Parsoid to point to your MediaWiki instances.
   
           mwApis:
   
           - # This is the only required parameter,
   
             # the URL of you MediaWiki API endpoint.
   
            
   
             #  uri: 'http://localhost/api.php'
   
             uri: 'http://40.68.204.191/w/api.php'
   
             # before >>  uri: 'http://localhost/w/api.php'
   
             # The "domain" is used for communication with Visual Editor
   
             # and RESTBase.  It defaults to the hostname portion of
   
             # the `uri` property below, but you can manually set it
   
             # to an arbitrary string.
   
            
   
             # domain: 'localhost'  # optional
   
             domain: '40.68.204.191'  # optional
   
             # before >> domain: 'localhost'  # optional
   

5. 我还在/etc/selinux文件夹内的semanage.conf文件末尾添加了SELINUX=permissive。

我已按照以下说明安装 Parsoid 和 VisualEditor：

https://www.mediawiki.org/wiki/Parsoid/Setup

https://www.mediawiki.org/wiki/Extension:VisualEditor

VisualEditor 和 Parsoid 是我在 MediaWiki 上安装的新扩展。

下图包含我在尝试使用 VisualEditor 时在我的 wiki 上显示的错误：

Answer 1

您的节点应该是版本 6 或更高版本才能运行Parsoid 0.9.0，以检查此运行：

node -v

如果它不是至少版本 6 尝试更新节点，你应该能够这样做：

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

尝试将Config.yaml和LocalSettings.php中的地址更改为localhost
