Jenkins ansible插件找不到可执行文件

我在Amazon EC2上运行Jenkins - Docker容器中的master和单独盒子上的代理 . 我的playbook使用Jenkins Ansible插件执行Ansible脚本 .

我不得不在代理上安装新版本的Ansible . 我使用Running from Source指令从git安装了Ansible，并安装到 /home/ec2-user/ansible. 如果我ssh到代理并运行 which ansible 我按预期得到 ~/ansible/bin/ansible . 我在新安装的'Ansible executables directory'中输入了 /home/ec2-user/ansible/bin ，位于Manage Jenkins>全局工具配置页面 .

但是，当我运行我的Jenkins管道时，我得到了这个：

Running on docker-agent-1 in /home/ec2-user/jenkins/workspace/planet-healthcare-pipeline
[Pipeline] {
[Pipeline] pwd
[Pipeline] stage
[Pipeline] { (Download source and capture commit ID)
[Pipeline] sh
[planet-healthcare-pipeline] Running shell script
+ which ansible
which: no ansible in (/usr/local/bin:/bin:/usr/bin)

它说它正在 docker-agent-1 上运行（这是我的代理人的名字），如果我在那里，我可以看到Ansible . 詹金斯为什么不能找到ansible可执行文件？

UPDATE: 将PATH添加为环境变量后，它可以找到Ansible，但现在还有其他东西会中断 . 这是新的输出：

它's failing in the 2657372 stage--it can'找到 rails 来运行 rails db:migrate ，即使我知道它在容器中 .

为什么在代理上设置PATH会影响Docker容器内发生的脚本？
