无法在CentOS7上安装RabbitMQ Server 3.7.1 - 错误的erlang版本

Question

根据https://www.rabbitmq.com/which-erlang.html,我有正确版本的erlang .

但是当我尝试在我的CentOS7上安装rabbitmq-server-3.7.1时,它说我的erlang版本错了,我需要版本> = 19.3.

但我已经20岁了.

我究竟做错了什么？

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我的erlang版本:

test_user@test_machine: ~/Downloads
$  erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().'  -noshell
"20"

test_user@test_machine: ~/Downloads
$ erl --version

编辑:

这是我的erlang安装步骤:我从https://www.erlang-solutions.com/resources/download.html 20.1.7 64位版本下载了CentOS 7然后我跑了:

sudo yum install esl-erlang_20.1.7-1~centos~7_amd64.rpm

这里安装了" erl "包:

test_user@test_machine: ~
$ yum list installed | grep erl | grep -v perl
esl-erlang.x86_64                      20.1.7-1                        installed

使用新的CentOS 7 VM和esl-erlang_20.1.7-1~centos~7_amd64.rpmrpm产生这个结果.您可以看到yum无法解析某些依赖项.我不知道为什么.

出于这个原因,RabbitMQ团队生成零依赖性RPM文件.您应该从系统中卸载Erlang,然后从此处安装软件包.

在我的测试系统上,上面的软件包安装成功,然后是RabbitMQ.完整信息可在此处找到:
