时间：2022年07月15日
版本 yarn=1.19.1-1 node=14.0.0 bundler --version 1.13.6
RPC问题
Parallel::UndumpableException
Parallel::UndumpableException: ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation “public.brand_configs” does not exist LINE 1: DELETE FROM “public”.“brand_configs” WHERE (NOT EXISTS (SELE
sudo COMPILE_ASSETS_BRAND_CONFIGS=0 RAILS_ENV=production bundle exec rake canvas:compile_assetsunknown attribute ‘singleton’ for Delayed::Backend::ActiveRecord::Job.
下面记混了，不太对应 dirname: missing operand Try ‘dirname --help’ for more information. stat: cannot stat ‘/…/config/environment.rb’: No such file or directory su: Cannot fork user shell
sudo chown -R canvas public/dist/brandable_css
sudo /etc/init.d/canvas_init start
bundle 版本问题
bundle莫名其妙提示2.1X版本，但需要的是2.2，已经安装这个版本，但不能运行，是bundle -v最初都是2.2，某次之后变成2.1了，按照下述删除就好了 https://cloud.tencent.com/developer/ask/sof/224941

unsplash-js 包版本不一致导致出错
npm list --depth=0 package.json 中需要6.3.0，但实际安装的是7.0.0,重新安装指定版本的 npm install unsplash-js@6.3.0 --legacy-peer-deps
启动之后，页面变成了目录
检查/var/log/apache2/error.log，报错信息如下，又执行一次passenger安装、配置
