Thanks for your comments, yes, I change this version(the commit id of v1.9.0.beta1) as follows:  
`version: 82ed51450e4b2912d3c650acd7a8332f90de9dc4`  
And I execute the command:  
` cd /var/discourse`  
` ./launcher rebuild app`  
But it failed, the upload file is fail log.[fail log.txt](https://meta.discourse.org/uploads/short-url/8J6vPjhGmHoreAjzBxAjJndI1Y3.txt) (129.4 KB)
