pg_config is required to build psycopg2 from source. Please add the directory
containing pg_config to the $PATH or specify the full executable path with the
option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.
For further information please check the 'doc/src/install.rst' file (also at
<https://www.psycopg.org/docs/install.html>).

This is a known issue. Use the binary version instead:
pip install psycopg2-binary
EDIT:
You dont have 'pg_config' which is part of libpq-dev on Ubuntu. Install it with sudo apt-get install libpq-dev and try abgain.

Before starting the binary installation, export PATH like below:
export PATH=$PATH:/usr/pgsql-12/bin/
Note: Change 12 to your current PostgreSQL version.

Error during installtion of bluepy using pip 22.2

I also tried the "solution" discussed in this comment of a similar question, but this did not work for me. I´ve also tried reinstalling python, alongside pip, even if the output from above says that it is not a problem with pip.
These are the packages I installed with the Visual Studio Installer:
Now I don`t know what else I should try.
Thanks

See this github issue:
bluepy only runs on linux
And also The README on github:
Python interface to Bluetooth LE on Linux
This is why you are unable to install it on windows

maybe this help
python -m pip uninstall setuptools
pip install setuptools
pip install airflow

This is simply saying the build tool setup.py fails to build from source.
I am not so technical in the aspect of building from source, so I can't tell you exactly what to do with your .tar.gz file to make it all right.
If you have pip installed on the machine (which I assume you do), then simply type:
pip install apache-airflow
The long version:
python3 -m pip install apache-airflow
If you intend to use celery together with Apache Airflow, I suggest:
python3 -m pip install apache-airflow[celery] for full installation.
Refer to the documentation of Apache Airflow for more info.

Issue with pip install in virtual environment - Cargo, the Rust package manager, is not installed or is not on PATH

I am using a python virtual environment to work on a project. After setting up my venv and pulling from git I tried to pip install -r requirements.txt but am getting an error below.

Any idea how to fix this? I installed rust but no fix.

faced the similar problem. after installing 64bit version of python everything is working fine.

The above error is caused by a rust package
pywinpty
all you need do is to remove it from requirements.txt file
and redeploy your app.

Simply install the dependency:
curl https://sh.rustup.rs -sSf | sh
Source: https://doc.rust-lang.org/cargo/getting-started/installation.html

Try installing the rust programming language. It seems like you have a dependency that uses rust. I recommend using brew on OSX.
brew install rust
Otherwise use the rust install page. You can check that rust is installed properly with:
rustc --version
Once you are finished try again to pip install your requirements file.
