Обсуждение: v2.0-rc1 not starting, runtime not building

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"

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).

(pgadmin4) wbloos@wb:~/python-files/pgadmin4/runtime$ qmake
Project MESSAGE: Building for QT5+...
Project MESSAGE: Using QWebEngine...
Project MESSAGE: Building for Linux/Mac...
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 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?

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:

qmake "DEFINES += PGADMIN4_USE_WEBKIT"

Hi thanks for answering.

It seems that we were talking about different products that both go by the name "yarn". I deinstalled cmdtest and installed the yarn that is a dependency manager for javascript.

I also checked out REL-2_0-RC1 again.

Then:

(pgadmin4) wbloos@wb:~/python-files/pgadmin4/web$ yarn install

(pgadmin4) wbloos@wb:~/python-files/pgadmin4/web$ python pgAdmin4.py

The errors persist.

qmake "DEFINES += PGADMIN4_USE_WEBKIT"

Ah, when i use that, it builds. With the warning that i should definitely use Qt 5.5.0

Which i do, afaik. dpkg -l tells me that i have version 5.5.1 of qt5-default:amd64, qt5-qmake:amd6, pyqt5-dev, python3-pyqt5 and many more derived package names.

When i run the runtime, it misses flask. Which is in the requirements.

pip freeze says: Flask==0.11.1

​It seems the node version used is outdated. Please upgrade to latest version of node and then run `yarn install`

Any ideas considering the runtime trouble with flask?

oops, turns out i overlooked that i need to run make too, not just qmake. So i was actually running an old executable.

make gives me ld errors. Any idea?
