Cannot install tesserocr - python-3.x

I try running pip install tesserocr and I get the following error...
error: 'cinttypes' file not found
#include // PRId32, ...
^~~~~~~~~~~
1 error generated.
error: command 'gcc' failed with exit status 1
Failed building wheel for tesserocr
I've searched the entire web. I even tried compiling the source code and then running pip install . but this gave me the exact same error. How can I fix this?

there are various questions like this topic.
tesserocr is compiled during installation so you have to install also the development packages needed.
Which these are depends on your OS distribution

Can not install psycopg2 on Mac 12.3, I keep getting this error

Ive recently bought a MacBook Pro and was setting it up for some python and Django programming but I ended up having problems installing psycopg2, I've tried several things already and none of those worked for me, here left the error,

Error: pg_config executable not found.
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>).

note: This error originates from a subprocess, and is likely not a problem with pip.

It shows it is not a problem with pip but with setup.py but can not find anything,
any help would be welcomed
Thanks
As Alex mentioned, it is PostGreSQL being not installed on your system that throws up the error
Install PostGreSQL and it will all work fine
Try this
❯ brew install postgresql
# If you open a new terminal tab you will see that pg_config is available
❯ export CPPFLAGS="-I/opt/homebrew/opt/openssl#1.1/include"
❯ export LDFLAGS="-L/opt/homebrew/opt/openssl#1.1/lib -L${HOME}/.pyenv/versions/3.8.10/lib"
❯ python -V
Python 3.9.13
❯ pip install psycopg2-binary==2.8.6```
Try using the following command:
pip3 install psycopg2-binary
Late, but I just had this problem and nothing I was finding was fixing it. I was trying to install the requirements.txt for an ongoing project on a new Mac. Eventually I remembered it's a postgresql package and I hadn't installed postgresql yet. As soon as I installed postgresql and tried installing psycopg2 again, it worked fine with no errors.

ERROR: Failed building wheel for opencv-python
I suspect issue is with scikit-build. I checked I have ninja, make/gcc all available. I set manually CMAKE_MAKE_PROGRAM=/usr/bin/make.
But still failed with same error. I
You are missing dependencies. Please see this part of the error message you have provided above:
Building Linux wheels for Python 3.6 requires a compiler (e.g gcc).
It can be installed using debian package manager:
sudo apt-get install build-essential
Therefore, please use apt-get to install the build tools required to build your package.
Run pip3 install -U pip before install opencv-python.
Finally figured out, when I installed locally I had a requirements with version 4.1.x and no issues. When I install with the dependencies, it fetches the latest version 4.4 and the issue is that 1) pip version is 19.1 and2) since 4.3 opencv, the wheels has been replaced.

Gcc error, No such file or directory "Python.h" -- installing pyAudio on centOS7

I have python 3.6.8 installed on CentOS7 and I'm trying to install pyaudio with
sudo python3.6 -m pip install pyaudio
This format worked to install a number of other things right beforehand, but if I try to use it here i get the following error
src/_portaudiomodule.c:28:10: fatal error: Python.h: No such file or directory
#include "Python.h"
^~~~~~~~~~
compilation terminated.
error: command 'gcc' failed with exit status 1
----------------------------------------
pip install pyaudio yeilds the same results
I have read the question and answer here but I still cannot figure it out
Any advice in installation? Thank you in advance!
fatal error: Python.h: No such file or directory
It looks like pyaudio is compiling some C code who require Python.h, to fix your issue check this answer https://stackoverflow.com/a/21530768/9799292
(also, "pip install pyaudio" prints "bash: pip: command not found")
To fix this try to install pip by running this command
sudo yum install python3-pip

unable to install some python modules

I am working on windows 8.1 .When i try to install some python(python 3.4) modules and packages like IMDBPY using pip :
pip install imdbpy
I get the following error code:
Command "python setup.py egg_info" failed with error code 1 in C:\Users\ISHAN~1.
NIT\AppData\Local\Temp\pip-build-uyc40bdk\imdbpy.
This same error message is occurring with many python modules and packages.
Although i have checked other similar questions on stack overflow but they could not solve my problem.

Installing OpenCV on Node problems

I have installed all the dependencies and have all compilers installed etc. Then when I finally try to install OpenCv in Node.js with Node Package Manager, I get the following error:
/bin/sh: pkg-config: command not found
gyp: Call to 'pkg-config --cflags opencv' returned exit status 127. while trying to load bind
Has anyone had the same problem?
