Failure Installation of Pipeline

[panglong]

Thanks a lot for your work and your help!

After running the script below
pltest@103server:~/soft/20190603_kubeflow$ ./kubeflow-tools/install-kubeflow.sh

there is an error reported as below:
.....
application.app.k8s.io/mykubeflow created
The CustomResourceDefinition "scheduledworkflows.kubeflow.org" is invalid:

• spec.version: Invalid value: "v1alpha1": must match the first version in spec.versions
• status.storedVersions[0]: Invalid value: "v1alpha1": must appear in spec.versions

Could you please give some hint?

When the pipeline component is disabled by editing the env.sh under mykubeflow such as:
....
3 KUBEFLOW_VERSION=0.5.1
4 #KUBEFLOW_COMPONENTS='"ambassador","jupyter","notebook-controller","jupyter-web-app","profiles","centraldashboard","tf-job-operator","pytorch-operator","spartakus","argo","pipeline"'
5 KUBEFLOW_COMPONENTS='"ambassador","jupyter","notebook-controller","jupyter-web-app","profiles","centraldashboard","tf-job-operator","pytorch-operator","spartakus","argo"'
6 KUBEFLOW_EXTENDEDINFO=false
7 KUBEFLOW_KS_DIR=/home/pltest/soft/20190603_kubeflow/mykubeflow/ks_app
....

There is no error reported.

After running ./kubeflow-tools/install-kubeflow.sh, the output is:
....
