i want to install the library telethon
It says i should execute this line of code
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade telethon
The first command works, it has a bunch of warnings but it seems to work.
But the second command says:
ERROR: Could not find a version that satisfies the requirement telethon (from versions: none) ERROR: No matching distribution found for telethon
So what i am doing wrong?
I am using windows
To install a virtual env and your package:
$ python --version
Python 3.6.9
$ python -m venv venv
$ source venv/bin/activate
(venv)$ pip install -U pip setuptools
(venv)$ pip install telethon
(venv)$ python

Type "help", "copyright", "credits" or "license" for more information.
Now try to load telethon:
>>> import telethon
>>> telethon.__version__
'1.23.0'
I have found the solution:
I just have to run VS code editor as "admin"

I have installed multiple versions of python like 3.8.5 and 3.9.2 in my Linux Ubuntu system. I want to install pyaudio module in 3.9.2 version.
For this, I have used a command: pip3 install PyAudio and I am getting this error - error: Microsoft Visual C++ 14.0 is required.
I have also used python unofficial libraries and tried to install pyaudio but it shows this error -
ERROR: PyAudio-0.2.11-cp39-cp39-win_amd64.whl is not a supported wheel on this platform.
Then I used these commands for the same -
sudo apt-get install libasound-dev portaudio19-dev libportaudio2
libportaudiocpp0
sudo apt-get install ffmpeg libav-tools
sudo pip install pyaudio
After this when I import pyaudio module, it shows module not found error. But when I tried to re-install the module, it shows requirement already satisfied.
Then I executed the command:
sudo -s
python3
import pyaudio
Now it shows no error. It seems that pyaudio module has been installed in python 3.8.5 version and not in python 3.9.2 version. However, I used virtual environment of older python version and installed speech recognition, pyaudio which worked well.
I want to use pyaudio module without using virtual environment without any errors. Please help.

Check in the usr/bin and usr/local/bin for all python instances.
The installation of python3 is probably linked to python 3.8.5. But there might be a python3.9.
You could check for other python instances in the above folders by running the below commands:
ls -ls /usr/bin/python*
ls -ls /usr/local/bin/python*
If so, you can run the commands with python3.9, but i would recommend cleaning up the unused installations.
I am using Anaconda Python and used the following to install jpype:
conda install -c conda-forge jpype1
I have GCC installed:
Python 3.6.1 |Anaconda 4.4.0 (x86_64)| (default, May 11 2017, 13:04:09)

and I did not get any error during installation.
conda install -c conda-forge jpype1
Collecting package metadata: done
Solving environment: done
# All requested packages already installed.
If I run pip search jpype I will get the following:
jtypes.jpype (0.6.3b3) - A Python to Java bridge (ctypes/cffi-based JPype).
JPype1-py3 (0.5.5.2) - Python-Java bridge. Fork of the jPype project by Steve Menard (http://jpype.sourceforge.net/), with the modifications applied by Luis Nell
(https://github.com/originell/jpype)
but still cannot call the library
>>> import jpype
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'jpype'
It might be because it is installed as a Python 2 package and you're running Python 3 or the opposite.
To specifically install the package for Python 3, try entering this command:
pip3 install jpype1
or
python3 -m pip install jpype1
To specifically install the package for Python 2, try entering this command:
pip2 install jpype1
or
python -m pip install jpype1
I found the problem.
By mistake, I had two versions of Anaconda 3.6 and 3.7 which was causing the problem.

Also, I tried to import it via PyCharm's Project Interpreter. It wants to installation with pip. (pip install opencv-python and pip install cv2)
When I installed that, I followed these steps
What is the problem that I cannot see?
Those instructions are outdated, and using apt-get puts pieces outside of the virtual environment, where pip won't see them to freeze.
Within a virtual environment, try
pip install --upgrade pip
pip install opencv-python
The --upgrade might not be necessary, but has helped me out of weird pip failures in the past.

Just encountered this problem myself. The solution is making sure the dependencies are available in your path.
In my case, I'm running with Anaconda Python and had anaconda2/bin in my path but not anaconda2/lib.
I added the following to my zshrc:
export PATH="/Users/$ME/anaconda2/lib/python2.7/site-packages:/Users/$ME/anaconda2/lib/python2.7:/Users/$ME/anaconda2/lib:$PATH"
Then source ~/.zshrc (or your respective shell resource file) and you're good.
I'm following the Python GTK+ 3 Tutorial and I'm trying to get a working install running in virtualenv. I have python3-gi installed through the Ubuntu package manager already. Things look like this:

Running virtualenv with interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in py3/bin/python3
Also creating executable in py3/bin/python

As you can see, python3-gi is obviously not available within virtualenv but I am not sure how to install it since python3-gi is installed through my package manager and not with pip.
It is now possible to resolve this using vext. Vext allows you to install packages in a virtualenv that individually access your system packages. To access gi, do the following:
pip install vext
pip install vext.gi
Update 2018 – Debian Stretch
Install GTK+ 3 / GIR.
apt install libcairo2-dev libgirepository1.0-dev gir1.2-gtk-3.0
Create a virtual environment.
python3 -mvenv venv
Install pygobject (pycairo should come as a dependency).
venv/bin/pip install pygobject
Update 2018 – macOS
Install GTK+ 3 and Gobject Introspection with Homebrew.
brew install gtk+3 gobject-introspection
Create and activate a virtual environment.
python3 -mvenv venv
Install pygobject (pycairo should come as a dependency).

Original answer
This is what I did to get GTK+ 3 within a Python 3.5 virtual environment on OS X 10.11.
Install GTK+ 3 with Homebrew.
brew install gtk+3
Create and activate a virtual environment.
pyvenv-3.5 venv
source venv/bin/activate
cd venv
Install pycairo on the virtual environment.
export PKG_CONFIG_PATH=$VIRTUAL_ENV/lib/pkgconfig
curl -L https://cairographics.org/releases/pycairo-1.10.0.tar.bz2 | tar xj
cd pycairo-1.10.0
export ARCHFLAGS='-arch x86_64'
python waf configure --prefix=$VIRTUAL_ENV # It's ok, this will fail.
sed -i '' '154s/data={}/return/' .waf3-1.6.4-*/waflib/Build.py # Bugfix: https://bugs.freedesktop.org/show_bug.cgi?id=76759
python waf configure --prefix=$VIRTUAL_ENV # Now it should configure.
python waf build
python waf install
unset ARCHFLAGS
cd ..
Install pygobject on the virtual environment.
export PKG_CONFIG_PATH=$VIRTUAL_ENV/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig
curl -L http://ftp.gnome.org/pub/GNOME/sources/pygobject/3.12/pygobject-3.12.2.tar.xz | tar xJ
cd pygobject-3.12.2
./configure CFLAGS="-I$VIRTUAL_ENV/include" --prefix=$VIRTUAL_ENV
make
make install
cd ..
Profit.

Python 3.5 downloaded and installed from PSF.
I haven't found a proper solution to this. When I run into situations where I can't get something to install into a virtualenv directly, I symlink it there and it works fine (there are probably exceptions, but this is not one of them).
ln -s /usr/lib/python3/dist-packages/gi /path_to_venv/lib/python3.4/site-packages/
Not elegant in the slightest; seems nicer than giving the virtualenv full access to all system packages though (via --system-site-packages).
The pip package name is somewhat counterintuitive - use pip install PyGObject.
I installed pgi via pip, which may be an option. It is apparently API compatible with PyGObject and so far seems to work ok running Gtk.
On Ubuntu (tested in 19.04), you can download the package and then install it as follows:
apt-get -y download python3-gi
dpkg-deb -x <package>.deb <virtualenv path>
In Ubuntu, the name of the downloaded package is python3-gi_3.32.0-1_amd64.deb.
