版本
yarn=1.19.1-1
node=14.0.0
bundler --version 1.13.6

RPC问题

git clone 下载代码一直报error: RPC failed; curl 18 transfer closed with outstanding read data remaining fatal: the remote end hung up unexpectedly错误的解决思路

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_assets

unknown 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

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

HTTPS ssl unable to verify the first certificate

rce的配置文件.env增加 NODE_TLS_REJECT_UNAUTHORIZED=0

FetchError: request to https://lms.xxx.edu.cn/api/v1/courses/1/pages?sort=title&per_page=50 failed, reason: unable to verify the first certificate

FATAL: role “root” does not exist

delayed_job.log报错FATAL: role "root" does not exist，网上搜索都说是postgresql不能root启动，创建root账号登都无效。
进入log目录ll查看发现delayed_job.log文件所有权是root，production.log所有权是canvas，
切换用户su -u canvas，重启解决
