解决jenkins流水线报错did not complete successfully: exit code: 127

详细信息如下：

4.812 /bin/sh: ENTRYPOINT: not found
 
ERROR: failed to solve: process "此处省略; \t\t\t\t\t\tENTRYPOINT [\"node\",\"main.js\"]" did not complete successfully: exit code: 127
 
Stage "deploy" skipped due to earlier failure(s)
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] End of Pipeline
ERROR: script returned exit code 1
 
Finished: FAILURE

可以看到depoly的上一步出错了，导致deploy较早退出，整个过程结束，从报错信息看到核心在于：ERROR: failed to solve: process下面的

所描述的正是脚本中关于Dockerfile的部分，仔细检查所写的指令，发现在ENTRYPOINT的前一句后语法不正确：

RUN   a ; \

           b ; \

           c ; \

ENTRYPOINT ["node","main.js"]

其中a、b、c都是命令行，此处简写方便观察，很明显c这里已经是RUN指令的最后一处，应去掉行后的 ;\ 符号，否则会把ENTRYPOINT 这一行也算为RUN指令的一部分。

因此，去除多余的;\ 符号，保存，再次构建就成功了。
