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

这错误猜的到应该就是crontab里缺ruby的什么环境变量,但是不会ruby,一点头绪没有,找了好几天,终于找到了:

rvm cron setup

就这个

#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

会自动在crontab里加上这一堆环境变量.

好坑啊!!!
