Setting enviroment with VSCODE

[yensei (Julio)]

Hi, My name is Julio. I’m newie with tryton and a junior developer with python. So I need a little help to setting up my enviroment in vscode to debug.

I was trying create my launch.json file to run a debug mode, but not lucky with that.
My launch.json

      {    
    "version": "0.2.0",
    "configurations": [       
        {
            "name": "Run Server Tryton",
            "type": "python",
            "request": "launch",
            "program": "${workspaceFolder}/trytond/bin/trytond",
            //"program": "${file}",
            "console": "integratedTerminal",
            "args": ["--config" ,"/work/tryton-workspace/tryton-env/trytond.conf",
                     "--logconf","/work/tryton-workspace/tryton-env/trytond_log.conf", 
                     "--dev"]
        }
    ]
}

The error was ‘trytond’ is a package and cannot be directly executed.

thanks in advance

Hi Julio,

Did you create a virtualenv ? trytond executable should be in the bin folder of your virtualenv path.

Another thing you could do is adding a pythonPath variable in your launch.json

“pythonPath”: “path_to_your_virtualenv/bin/python”

and “program” variable should be just “trytond”

[yensei (Julio)]

@maxx

pythonPath

Thanks for answer me.

Yes I have a virtual enviroment but adding that vscode shows me an error

Do you know why it not works for me?

[yensei (Julio)]

I will answer myself ,

My var pythonPath was already configurated on my settings.json.

My share my settings.json
{
“python.pythonPath”: “/usr/bin/python3”,
“python.venvPath”: “/work/tryton-server/tryton-env/bin/activate”
}
And my launch.json remains equals, I only deleted python path from there.

Saddly I have this error because I try to execute bin/trytond, with which file I should starts my tryton server?

Blockquote
/usr/bin/python3: No module named trytond.main; ‘trytond’ is a package and cannot be directly executed

Sorry, I really missed this part

@maxx

and “program” variable should be just “trytond”

My new error after changed

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

@yensei

"program": "${workspaceFolder}/trytond/bin/trytond"

It looks like this path point to a directory instead of the trytond starting script.

[yensei (Julio)]

Hi Cédric, Thanks for answer me.

@ced

It looks like this path point to a directory instead of the trytond starting script.

I changed that when noticed that Maxx had said me on her response. My launch looks like this now

    {
            "version": "0.2.0",
            "configurations": [       
                {
                    "name": "Run Server Tryton",
                    "type": "python",
                    "request": "launch",            
                    "program": "trytond",
                    "console": "integratedTerminal",
                    "args": ["--config" ,"trytond.conf",
                             "--logconf","trytond_log.conf", 
                             "--dev"]            
                } 
            ]
        }

But I have the above error still

ImportError: can't find '__main__' module in 'trytond'

@yensei

My share my settings.json
{
“python.pythonPath”: “/usr/bin/python3”,
“python.venvPath”: “/work/tryton-server/tryton-env/bin/activate”
}

try with variable pythonPath : “path_to_your_virtualenv/bin/python”
Did you install trytond in your virtualenv ?

[ced (Cédric Krier)]

If you did not installed trytond by only cloned the source code, then the trytond/bin/trytond is not in your path. And it looks like the trytond is so Python tries to run it by finding a __main__.py file which does not exist.
So you have to install trytond or have trytond/bin/trytond in your path.

[yensei (Julio)]

I believe a I did, if trying to install like I know the log show me as installed.

Please let me know if my way to install is wrong

@maxx

try with variable pythonPath : “path_to_your_virtualenv/bin/python”
Did you install trytond in your virtualenv ?

I recreate a new virtual enviroment called venv, and I put python on the pythonPath so I removed venvPath, now my setttings

{
    "python.pythonPath": "venv/bin/python"
}

if I run from the internal terminal it works fine, doing this

/> trytond --config trytond.conf --logconf trytond_log.conf

But it fails with my launch.json

[yensei (Julio)]

Hi,

I was able to run at now, putting “program”: “trytond/bin/trytond” like Cédric said. But now it throw a exception and show me this error

 No module named trytond.__main__; 'trytond' is a package and cannot be directly executed

There are something I missed to install?

[EDITED]
This problem was solved removing --dev modifier from my args. Now all is working perfectly thanks you both.

I don’t remember even for what reason I putetd it, or what it does.
