我正在尝试通过GitHub代码空间运行instructure的canvas-lms，遇到了以下问题。我使用的是免费的4核心计划。代码空间设置的存储库和说明可以在here中找到。有人在尝试在GitHub代码空间中运行他们的forked canvas-lms时使用bundle exec rails canvas：compile_assets后遇到过这个问题吗？我应该能够在这样做之后运行bundle exec rails db：initial_setup以接收身份验证提示。
我运行以下命令：
sudo apt-get update
sudo apt-get -y install postgresql-12 zlib1g-dev libldap2-dev libidn11-dev libxml2-dev libsqlite3-dev libpq-dev libxmlsec1-dev curl build-essential

我找到了一个解决方案。请不要把这个当作好的建议-这只是我在Github代码空间中运行开发Canvas环境时的一个工作。我还没有遇到过一些未来错误的可能性很大，但这已经足够让我在开发项目中使用Canvas代码空间了。
我看到 Post is not a class 错误。当然是，但我在网上搜索了类似的错误，并看到关于重复类名的讨论是一个潜在的问题。因此，我改变了一些事情。
我能够再次运行canvas：compile_assets命令，并且没有得到相同的错误。然而，在大部分编译工作似乎正常后，我得到了一个新的错误。错误：
--〉完成：'js：webpack_development' in 100.79s rails aborted！Parallel：：UndumpableException：活动记录：：语句无效：PG：：未定义表格：错误：关联“public.brand_configs”不存在行1：DELETE FROM“public”.“brand_configs”WHERE（NOT EXISTS（SELE... ^ /workspaces/canvas-lms/config/initializers/active_record.rb：1430：in

讨论给了我一个测试的命令：
COMPILE_ASSETS_BRAND_CONFIGs=0 RAILS_ENV=production bundle exec rake canvas：compile_assets
这个命令显然是“production”，但它让我顺利地通过了compile_assets。我能够使用凭证初始化DB，在代码空间中启动Canvas，并且迄今为止能够将其用于我正在进行的开发。
