I'm trying to install psycopg2, using pip, on Fedora.
I get the message:
"pg_config executable not found."
In ubuntu, this problem can be resolved by installing the libpq-dev and python-dev packages. There's no clear analogous solution in Fedora.
You are probably searching python-devel and postgresql-devel packages.

I tried to download pyspider for python 3.11.1 and faced with this problem:
I tried to install old pip version and tried to install in python 3.10 and it still not working. What should I do to resolve this problem?
If you are mentioning this library, I see that the last release was in 2018 and the last supported python version is 3.6 in v0.3.9. You have to downgrade it to Python 3.6.

and I get:
Fatal error in launcher: Unable to create process using '"c:\program files\python37\python.exe" "C:\Program Files\Python37\Scripts\pip.exe" install virtualenv': The system cannot find the file specified.
I would like to hear if someone could help me.
This should work
python -m pip install virtualenv

I have tried pip, easy_install, pkg update, pkg install, and building from source and all have failed. All I want to do is be able to have python 3.5 run and I am getting desperate at this point.
Is your freeNAS server the kind that is built on Debian?
If so you can try:
sudo apt-get update
sudo apt-get install python3.5
See:
https://askubuntu.com/questions/682869/how-do-i-install-newer-python-versions-using-apt-get
If the above doesn't work, try posting here the output from these commands:
uname -a
cat /etc/issue
cat /proc/version

I'm trying to run a scrapy project in python 2.7 but I have that problem. I had other problems but solved them with sudo pip install ... I looked up in google but can't find any solution to this problem.
Have you installed the requests library?
sudo pip install requests
requests.structures is simply a module in that package.

So far I've tried these methods to install the package
pip install rsa andpython setup.py install
but it seems like I installed the one for python2.7.
How can I install the one for python3.2? Or convert the 2.x to 3.x?
Many thanks.
You simply specify the version you wish to use, e.g. python3 setup.py install.
