ruby cronjob錯誤: `require': cannot load such file -- bundler/setup (LoadError)

這錯誤猜的到應該就是crontab裏缺ruby的什麼環境變量,但是不會ruby,一點頭緒沒有,找了好幾天,終於找到了:

rvm cron setup

就這個

#sm start rvm
PATH="/usr/local/rvm/gems/ruby-2.6.3/bin:/usr/local/rvm/gems/ruby-2.6.3@global/bin:/usr/local/rvm/rubies/ruby-2.6.3/bin:/usr/local/rvm/gems/ruby-2.6.3/bin:/usr/local/rvm/gems/ruby-2.6.3@global/bin:/usr/local/rvm/rubies/ruby-2.6.3/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"
GEM_HOME='/usr/local/rvm/gems/ruby-2.6.3'
GEM_PATH='/usr/local/rvm/gems/ruby-2.6.3:/usr/local/rvm/gems/ruby-2.6.3@global'
MY_RUBY_HOME='/usr/local/rvm/rubies/ruby-2.6.3'
IRBRC='/usr/local/rvm/rubies/ruby-2.6.3/.irbrc'
RUBY_VERSION='ruby-2.6.3'
#sm end rvm

會自動在crontab里加上這一堆環境變量.

好坑啊!!!
