或许可尝试将localhost修改为您自己的主机名称

During a SAS 9.3 installation, a SAS environment URL dialog box might appear if the initial values are undefined.
When this dialog box appears, enter values for the SAS environment URL settings. The values should be in the following form:
http://hostname:port/SASLogon/sas-environment.xml
For hostname, use the fully qualified hostname of your machine, and for port, use the default port for your Web application server. For example, if you are using JBoss, you might enter values similar to the following:
http://my_hostname.sas.com:8080/SASLogon/sas-environment.xml
