I had pgadmin4 v1.0, then I updated it without any problem to v1.1 and then v1.2.
After v1.3 was released I tried to do the update to v1.3. I followed the same steps as I did before. (Similar to How to install pgAdmin 4 in desktop mode on Ubuntu 16.04 but using
conda to create the virtual environment and with python 3.5, I also tried with
conda + python 3.6 and with
virtualenv and python 2.7 and I got the same result)
However, after the install was done I launched pgAdmin4 and I got the following error message that popped up in a modal:
Error loading script - /sqleditor/sqleditor Error message undefined
Nothing appears in the terminal.
This error appears in the browser console:
http://localhost:5050/lib/codemirror.js [HTTP/1.0 404 NOT FOUND 6 ms]
I rolled back to v1.2, which still works fine and I have no idea how to solve this issue.
I had the issue with both Ubuntu 14.04 and Ubuntu 16.04 with Firefox 52.0 64 bits.
