Can't setup flask

LimanOP

I did everything that docs said. Except venenv thingy. I made WWW python site from the panel and configured python latest.

Then, I followed the docs to setup flask. Removed index html from public. added "passenger_wsgi" "application.py" at "/usr/home/LimanOP/domains/testpy.serv00.net/public_python". Then it is giving me 500 internal server error.

Code is same as the docs.

In the error.txt it is saying flask module not found.

When I do "pip install flask" it is doing user insstallation instead site-packages. And then the same error. It is saying site-package is not accessable.

$ pip install flask Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: flask in /usr/local/lib/python3.10/site-packages (2.3.2) Requirement already satisfied: Werkzeug>=2.3.3 in /usr/local/lib/python3.10/site-packages (from flask) (2.3.3) Requirement already satisfied: Jinja2>=3.1.2 in /usr/local/lib/python3.10/site-packages (from flask) (3.1.2) Requirement already satisfied: itsdangerous>=2.1.2 in /usr/local/lib/python3.10/site-packages (from flask) (2.1.2) Requirement already satisfied: click>=8.1.3 in /usr/local/lib/python3.10/site-packages (from flask) (8.1.3) Requirement already satisfied: blinker>=1.6.2 in /usr/home/LimanOP/.local/lib/python3.10/site-packages (from flask) (1.7.0) Requirement already satisfied: MarkupSafe>=2.0 in /usr/local/lib/python3.10/site-packages (from Jinja2>=3.1.2->flask) (2.1.2)

You can use pip without your own Virtualenv, if you want. We recommend to use a Virtualenv.
There is no problem with flask installation as you can see in the provided log.

What you can do is check the application's log here: /usr/home/LimanOP/domains/testpy.serv00.net/logs/error.log
And if you want to use pip without Virtualenv be sure you are using a default Python version (now it is 3.10) for your website. For another Python version than default, you need to use a Virtualenv.

What you pasted means that you are not following the instructions on the help page https://docs.serv00.com/Flask/, including likely not unlocking binexec and not creating a virtualenv, as well as not installing Python packages within it.

I have reviewed the document and as requested, the passenger_ Wsgi.py, but there was an exception when executing the passenger start, and I still cannot solve the problem

mu228

admin
I plan to download PCRE according to the exception prompt

No permission

Please ignore the pcre path, as a passenger start will result in the same outcome in any path executed

admin

What you pasted means that you are not following the instructions on the help page https://docs.serv00.com/Flask/

The instructions does not mention anything about having to manually start Passenger. There is no visible virtualenv (including an activated one), you haven't added a page specifying the Python binary from virtualenv, and you haven't installed packages in the virtualenv.

mu228

admin Must virtual environment be necessary?

admin

The description indicates the use of Virtualenv. If you want to use it without Virtualenv, you will need to resolve any difficulties on your own.

admin I'm sorry, I studied for 3 days,but in my current capacity, I may not be able to pull this off. I created a virtual environment based on the documentation. Had a lot of problems. Pip install flask, which prompts that the module has been installed, but I did not prompt for this module when I imported it. Later, I used the WHL file to specify that it was installed in/Lib/Python 3.10/site-packages, which seemed fine. But I saw you say you don't need to manually activate the passenger. I use a Python passenger_wsgi.py. Nothing from web is 403. Only Python application.py output 127.0.0.1: 5000, but not accessible on the extranet. The documentation is too professional for me. Neither Google nor CHATGPT can give me a correct answer. Only ask for your help. Sorry Sorry to trouble you!

Can I give you my account password so you can run it on Tmux for me. Maybe I can check. .bash_history, study. No one around me uses the SERV00 server. So I have no one to turn to.

admin

mu228 When you visit your site the passenger_wsgi.py is executed automatically by our webserver, you shouldn't run any scripts from SSH.

If you have a problem like We're sorry, but something went wrong on your website then check the log at ~/domains/DOMAIN/logs/error.log

mu228

admin thx,I think it's because I don't understand this method. I've been learning Python xxx.py or Flask Run methods. So the problem kept occurring, and I made a serious mistake by putting two py files in the public folder. After understanding this issue just now, I placed it in public_ In Python, web pages have made good progress now.

show:
We're sorry, but something went wrong The issue has been logged for investment Please try again later
I will continue to deepen my learning until I succeed ！I'm sorry to take up your time.

mu228

admin Sorry, I have another question. I followed the document requirements to pip install Flask in a virtual environment. Why does he prompt that it has been installed? It shouldn't be a clean environment, there should be nothing. It causes me to have a Flask when I pip the list, but when I interact with Python, it will prompt me that the library is not available！

admin I barely solved the problem using 'pip install -- target=/usr/home/mu228/env/lib/python3.10/site packages flag'. The website successfully displayed Hello World, but this method is definitely not the correct answer. Please tell me the correct answer!

admin

It seems like the virtualenv wasn't activated during Flask installation. You can activate it by using source /usr/home/mu228/env/bin/activate or directly run pip in the virtualenv: /usr/home/mu228/env/bin/pip install Flask

I've had problems at the front before. So it's always been weird.

admin

Before installation, please enable the use of your own software - Binexec.
https://docs.serv00.com/Binexec/ - is an essential step. After activating that option (and re-login to SSH), the best is to recreate your virtualenv.

OK.

devil binexec on

thank you very much
