上传ConcourseCI管道时出现yaml unmarshal错误

Question

我尝试使用

将ConcourseCI管道上传到我的Concourse服务器

fly -t <my_target> sp -p my_pip -c pipeline.yml -l creds.yml

但上传终止时会显示以下错误消息：

fly -t local-docker sp -p siemens -c build/paas_ci_cd.yml -l config/credentials.yml
error: yaml: unmarshal errors:

我已将pipeline.yml粘贴到yaml验证器中，没有任何错误投诉。管道是使用erb模板生成的。产生错误消息的行现在显示缩进问题或缺少变量。
