Can't install pyFFTW with python 3.9 in Macos M1 - python-3.x

Any idea on how can I solve this issue?
I really need to install pyfftw into a conda environment, which already has the other libraries I need, such as tensorflow. Up until know, I could only install the other libraries correctly (namely tensorflow) for python 3.9.
I'm working on a Mac M1.
Here is the error output for the command pip install pyfftw:

The PyPA doesn't host a precompiled wheel for osx-arm64, so it is building from source. According to the documentation, when source building, one is required to have FFTW installed first. Fortunately, Conda Forge appears to be building this (including osx-arm64), so try
conda install -c conda-forge fftw
pip install pyfftw
Otherwise, I dropped an issue to the Conda Forge feedstock, noting that they should be capable of building an osx-arm64 build. Hopefully that will move forward and in the future one could avoid Pip and local compilation altogether.
UPDATE: the feedstock is now building for osx-arm64, so you should be able to use
conda install -c conda-forge pyfftw

Can't build Detectron2 on Windows 10

Although there's no official support for Detectron2 on Windows, there're many instructions available. I tried following these instruction, but ended up with the same error.

How to download psycopg2 on Mac OS

I am trying to get postgresql up and running on my computer to use with python3. From what I understand, I have to download postgresql and then psycopg2. I used the command
brew install postgresql
which worked without any error. I then proceeded to do
pip3 install psycopg2
but got the error
ERROR: Could not find a version that satisfies the requirement pyscopg2 (from versions: none)
ERROR: No matching distribution found for pyscopg2
I know that psycopg2-binary exists, but I would rather not install it unless I have to.
EDIT:
Turns out as wu.guan.feng.yue pointed out, I had a typo (fixed now). Unfortunately, I just got another error.

It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at
<https://www.psycopg.org/docs/install.html>).

You might have a typo "pscyopg2". Do you mean by pip3 install psycopg2?
Alright, I found the answer. I noticed one line of the error said
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
I looked it up finding this question: Git is not working after macOS Update (xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools).
Turned out the problem was that I needed to run the command
xcode-select --install
in order to update the Xcode Command-line Tools.

You obviously lack permissions to make the install you could use a venv or run cmd as an admin (idk I don't use windows)
to set up a venv run the following command in your projects directory whenever you start cmd
C:\> python3 -m venv ./.venv
and then run your install script
