我正在使用 ./launcher rebuild myapp 重新构建，但遇到了以下错误：

当前基础镜像：discourse/base 2.0.20191013-2320

如果需要其他信息，请告诉我。
谢谢！

你当前使用的是哪个版本？稳定版、测试版还是测试通过版？

3

稳定版

当我访问 Discourse 网站时，它显示我：discourse v2.3.6

4

看起来 @gerhard 在 10 天前已经修复了这个问题。当时有一些 6.0 的迁移操作导致 stable 分支出现了问题。

请运行以下命令：

git pull
./launcher rebuild app

如果您将 app.yml 重命名为 myapp.yml，则运行：./launcher rebuild myapp

然后重试。如果问题仍未解决，请反馈。

5

是的，我试过几次了。但不管用。

我已在 Akismet 插件中修复了迁移问题。请尝试重新构建您的应用以测试。
