Hi,
I just did a pull from Git and trouble starting pgAdmin4 since.
I am now at commit 512afd66182f463e6ce9515910205dcf0221e58c
This is on ubuntu 16.04.03, using python3 and firefox 55.0.2
I did a fresh pip install -r requirements.txt
With Debug = True, i got the following errors and execution aborted:
(pgadmin4) wbloos@wb:~/python-files/pgadmin4/web$ python pgAdmin4.py ERROR: [Errno 2] No such file or directory: 'run' 2017-09-11 17:18:39,412: ERROR pgadmin: Unable to generate javascript 2017-09-11 17:18:39,412: ERROR pgadmin: To run the app ensure that yarn install command runs successfully Traceback (most recent call last): File "pgAdmin4.py", line 79, in <module> raise Exception("No generated javascript, aborting") Exception: No generated javascript, aborting
With Debug = False, the server starts (Starting pgAdmin 4. Please navigate to http://127.0.0.1:5050 in your browser.)
But when visiting that page, there's no CSS is the background and a grey layer in the foreground, displayiong the text "Loading pgAdmin 4 v2.0-rc1.." without any progress.
I checked where the Erno 2 comes from, it's in the function try_building_js() of javascript_bundler.py . The line that calls yarn.
I tried entering the web directory and running yarn install, and that's where i find the same error again:
ERROR: [Errno 2] No such file or directory: 'install'
The same goes for "yarn run" and "yarn --run=bundle:dev"
If you're getting those errors when running yarn directly, that implies there's something wrong with your yarn installation. What is the full output from "yarn install" when run from the web/ directory?
Is there a file missing?
I'm not sure if this is also the cause of the web page not loading. The line of code is only executed if Debug=True
Also, the desktop runtime is (still) not building (same in both checked out versions).

Project MESSAGE: Using /home/wbloos/.virtualenvs/pgadmin4/bin/python-config Project MESSAGE: Python3 detected. Project ERROR: Unknown module(s) in QT: webenginewidgets
Even though i do have libqt5webkit5-dev installed.
Is there any other diagnosis that i can perform for more insight?
If you're using QT 5.0+, then it'll default to QtWebEngine, which I guess you don't have installed. QtWebKit is generally preferred for performance reasons; you can force the use of that with:
