Re: unable to start pgAdmin-4 on CentOS-7

Hello Community,

I have an issue starting pgAdmin4 on CentOS-7 and would appreciate any help in this regard -

I have downloaded the EnterpriseDB's Open Source PostgreSQL package (9.6 beta3) which includes pgAdmin4 as well.

When i tried starting the pgAdmin4, i get the following error -

[dba@localhost bin]$ ./pgAdmin4
