• Linux 4.4.0-66-generic x86_64
• Python 3.5.2

It is any solution for this? Thanks

Solution 1

You need to install Python3.5 development files, so run this command:

apt-get install python3.5-dev

The above command will install Python 3 headers to build uWSGI from source.

Solution 2

apt-get install build-essential python3-dev

From the uWSGI documentation:

uWSGI is a (big) C application, so you need a C compiler (like gcc or clang) and the Python development headers. On a Debian-based distro an apt-get install build-essential python-dev will be enough.

For Python3, just change that to python3-dev.

$ python3 --version Python 3.5.2 $ pip3 freeze uWSGI==2.0.15

Solution 3

For anyone with python 3.6 facing the same problem here is the step to solve it :

Get python 3.6 dev tools from this ppa:

sudo add-apt-repository ppa:deadsnakes/ppa

Then update your package list with :

sudo apt-get update

and then install your dev tools with 3.6 version

apt-get install build-essential python3.6-dev

Activate your virtual environment with and then install uwsgi:

pip install uwsgi

Solution 4

Debian have package depending on all supported Python 3 development packages:

apt-get install python3-all-dev

Solution 5

I have faced the same issue. I solve it by following:

sudo apt install libpython3.7-dev

If your python version is 3.6, then use 3.6 instead of 3.7. After that install uwsgi using pip:

sudo pip install uwsgi

Upgrading python to 3.9.7 solved the problem for me.

This works! Thanks!! now I have uWSGI installed in my virutal env. But i can not run it with python 3. I run with sudo uwsgi --http :80 --wsgi-file main.py --callable app --master --processes 8 --threads 2 and I see this line Python version: 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609]

Because sudo means to run some command as some other user (root by default), you can see this question.

[Alvaro B]

but if I don't run like sudo, I can not run it using port 80

@AlvaroB, just install proper python version in virtualenv. $ virtualenv -p python3.6 .venv and then $ . .venv/bin/activate and ' $ python --version ' must be 3.6.x

I have migrated to python3.6 and it's wokring fine. Thanks!

Thanks! You saved my time! I installed python3.7-dev as I use python3.7.9.

try this , sudo uwsgi --socket 0.0.0.0:5000 --protocol=http --plugin python3 --module wsgi:app
