问题标签 [learning-locker]

我安装了两个版本的 Learning Locker。在一个版本中收到了声明，但是我无法查看我以前的任何声明，因为 LL 似乎被卡住了

当我使用我的新版本 LL 时，没有收到任何语句，但是我确实收到了很多错误。

有人有想法么？

谢谢

我已经创建了一个 LRS 服务器并在 Learning Locker 中创建了一个客户端。创建新客户端时，会自动生成用户名和密码。但是对于 LRS 通信（语句），我们需要验证码。在文档中，它没有指定为 api 访问生成身份验证令牌。如果有人熟悉学习储物柜，请帮助我。

我正在尝试通过 PHP 和 TinCanPHP API 对存储在 Learning Locker 中的语句执行查询。通过这个答案，我能够从 Learning Locker 获取响应。以下是部分回复：

返回的语句列表具有权限protected，因此我无法访问它们。如何访问报表？我在这里想念什么？

我已经关注下面的链接好几天了，我在执行每个步骤时遇到了麻烦，但成功地为每一个步骤找到了解决方案，但不幸的是，当我执行命令“php”时我找不到解决方案工匠迁移”，您可以从下面的链接中看到； http://www.jpablo128.com/how-to-install-learning-locker/#comment-1498

它给了我一条错误消息；PHP 致命错误：在第 46 行的 /var/www/learninglocker/bootstrap/autoload.php 中找不到类“Patchwork\Utf8\Bootup”

我尝试了无数的解决方案，但我无法修复它。

我正在测试基于 MongoDB 的学习储物柜，它都在 ubuntu14.04 docker https://hub.docker.com/r/hadyrashwan/learninglocker-ubuntu14.04/内。我让它工作但我无法启动 Mongodb 自动尝试修复命令并将启动服务命令中的名称更改为 Mongodb 或 mongo 但不工作。但是运行Mongodb只是让它启动但我想自动启动它而不打开终端并让它保持打开状态以便系统继续工作

我正在尝试使用 TinCanPHP 查询存储在 Learning Locker 中的语句，但我只想检索在特定时间间隔内生成的语句。例如，我想要今天生成的所有语句。

我该怎么做？

我在学习储物柜本地设置时遇到错误。

无法加载http://127.0.0.1:3000/data/xAPI/statements：对预检请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。因此，不允许访问源“ http://localhost ”。

请帮忙。我已经在 server.js 中提供了 CORS 标头。

我在 AWS 上使用 Community AMI 安装了 Learning Locker，系统说它成功构建并运行，我可以使用 ssh 连接到我的服务器，但是当我访问我的实例的公共 DNS 时，我总是收到错误 404 not found，并且我的服务器正在运行nginx，ubuntu 10.4

我在使用免费 AWS 账户时没有技术支持

所以我该怎么做？

我是 xapi 的新手，我不知道将 mongo db 与 express 和 vtc-lrs 包的使用集成。这里我使用以下链接作为参考npm 包链接

我的代码是：

当我运行这张脸时，出现以下错误截图

最初，我对包含动词下的一些值（分数）的 xApi 进行了发布请求。成功调用 api 后，它返回一个令牌。

我的问题是我们可以更新相同的值（分数）吗？ 如果可以的话，请告诉我……！！！
