I currently am trying to install libvirt-python to a virtualenv.
When I run it I get this output

Without the virtualenv I'm able to import libvirt into my python shell.
The pip installation of libvirt-python requires the file libvirt.pc to be present on your system, because the installation script uses pkg-config to check the package details of libvirt.
For Debian, I found that this file is provided by the package `libvirt-dev'. So you could try
apt-get install libvirt-dev
or something equivalent for your distribution.
If you're on deb-based OS make sure you have libvirt-dev package installed

For Ubuntu/Debian OS,
apt-get install pkg-config
For Redhat/Yum OS,
yum install -y pkgconfig
For MacOS,
brew install pkg-config
2, pip install libvirt-python

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
<http://initd.org/psycopg/docs/install.html>).
According to error message, you can either 1. specify path, or 2. install psycopg2-binary using the command: pip3 install psycopg2-binary
Try this
sudo apt install libpq-dev python3-dev

I am trying to install the Python module simplecrypto on a Windows machine. To do this I run the following:
C:\Python36\Scripts>pip install simplecrypto
However, upon running this partway through the installation process I receive the following error:
...

Why is this the case?
An error occurs when it attempts to install PyCrypto, which is a requirement of the package. The GitHub README mentions:
If the dependency installation fail on Windows, you may want to use a
prebuilt installer. If you wish to compile it I suggest using the
Mingw tools as indicated here.
Install it from here and then compile by
install MinGW with C++ Compiler option checked add C:\MinGW\bin to
your PATH in PYTHONPATH\Lib\distutils, create a file distutils.cfg and
add these lines:
[build] compiler=mingw32
EDIT: Looks like I have to install Visual Studio 2015...Can I install dlib without VS 2015? I already have older versions pre-installed with Windows.
I am using Python 3.5, trying to install dlib on PyCharm in the terminal and this is what I am getting, and every search on these errors I do... I find stuff on Visual Studio which I don't have the GUI + I don't have vcvarsall.bat in the VC folder of any of the Visual Studio versions (8, 11, 12, 14). I have searched a good amount before posting this question on the Web.
Do I need to download Visual Studio latest version to get vcvarsall.bat ?

Solution found here: Using Anaconda installing manager..!
Running the following in PyCharm Terminal: conda install -c conda-forge dlib=19.4
I was able to use dlib! :)
Huge thanks to birryree in the comments for letting me know!
Open Anaconda Prompt in Administrative mode.
conda update conda 3. conda update anaconda
conda create -n dlib_env python=3.7
conda activate dlib_env
conda install -c conda-forge dlib
python
7.1 >>> import dlib 7.2 >>> dlib.version

I am using Ubuntu 16.
This is happening because you do not have dependency libraries installed on your system, specifically the ones for OpenGL - most likely you do not have mesa packages installed.
Follow the instructions for your specific distribution on how to install all of the needed dependencies at: https://kivy.org/docs/installation/installation-linux.html#using-software-packages
had the same problem. the following worked for me:
pip(3) install Cython==0.26
pip(3) install kivy
hope it helps

error: [Error 2] The system cannot find the file specified
In my system when I type make:
C:\Users\xxxxxx>make
'make' is not recognized as an internal or external command,
operable program or batch file.
So, clearly make is missing. But I installed make using conda:
C:\Users\xxxxxx>conda install mingw

Solving package specifications: ..........
# All requested packages already installed.

So I have mingw 4.7 already installed.
How could I remove the error and get the package?
Many thanks for the help.
make is not in your PATH.
Do echo %PATH% and check if the path to your msys utilities is in there. Otherwise you can edit this variable by following the instructions here: Adding directory to PATH Environment Variable in Windows
