But when I run in the directiy with file I want to check pylint text.py it writes
$ pylint test.py
bash: pylint: command not found
I didn't add path to pylint to PATH because I can't find its path. But when I run python and import pylint it imports ok. How could I run pylint from command line?
any python module can be run with python -m MODULE for instance I always use python3 -m pip since I can never manage to get the pip alias to work for the correct version 😋. so you can use pylint as:
python -m pylint test.py

I am trying to pip install a CLI and it successfully installs.
pip3 install databricks-cli
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

Thank you for your advice!
Sometimes, when you have multiple versions of Python installed (with multiple Python 3.X versions), using pip3 is not enough, as it does not necessarily install a package for the latest version of Python installed on your machine.
You can check what version of python your pip3 is using by using the pip3 --version command.
If you plan to run a script with Python 3.8 and need to install a package for this specific version of Python, you can use:
pip3.8 install PACKAGE or
python3.8 -m pip install PACKAGE

altgraph 0.10.2
ansible 2.8.0
asn1crypto 0.24.0
awscli 1.15.0
But when I'm trying to run any aws command I get command not found for example -
wwww:~ rgsd$ aws
-bash: aws: command not found
wwww:~ rgsd$ awscli
-bash: awscli: command not found
wwww:~ rgsd $ aws s3
-bash: aws: command not found
I also executed the command to include this in my $PATH.
export PATH=~/.local/bin:$PATH
But no success on that. I use Mac machine.
What am I doing wrong ?
For Modern macos/OSX, you need to find your ~/Library/Python/$version/bin directory and add it to your $PATH. This will help you locate the one where aws got installed.
$ ls -d ~/Library/Python/*/bin/aws
/Users/bbronosky/Library/Python/3.6/bin/aws
So based on that I added this line to my .bashrc
export PATH=$HOME/Library/Python/3.6/bin:$PATH
This link is helpful -

In an attempt to access and run Matlab code via Jupyter notebook and Python, I tried installing 'matlab_kernal' (w/ typo) and 'matlab_kernel' as suggested by a blog, I didn't realize I needed MatLab, not MatLab Compiler Runtime.
I received the error:
"Collecting matlab_kernal
Could not find a version that satisfies the requirement matlab_kernal (from versions: )
No matching distribution found for matlab_kernal"
As a work around, I found python code on GitHub that calculated the metric I wanted, but the author said I'd need to install 'MPI' from 'mpi4py'.
However, it seems my Terminal is now stuck on my previous installation attempts of 'matlab_kernal'. It lists my previous attempts to install these packages (see all white text above red error message in the attached screen capture).
I'm running: pip 18.1 from /anaconda3/lib/python3.7/site-packages/pip (python 3.7)
I've tried:
pip uninstall 'package'
Terminal restart
laptop restart
Screenshot of Terminal error
Please use:
pip install matlab-kernel
Try with conda as well:
conda install -c pchrapka matlab_kernel
I think you're making a typo with kernal.
I am on py3.7 with pip v19.3.
Output:
$ pip install matlab-kernel

Make sure that /usr/local/lib/python3.7/site-packages and /Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages are in the path.
Use the below code to temporarily append it to the path.:
import sys
print(sys.path)
sys.path.append('/usr/local/lib/python3.7/site-packages')
sys.path.append('/Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages')
print(sys.path)
import boto3
Make sure you have installed your package with the pip associated with a particular python, use:
python -m pip install <pkg>
instead of:
pip install <pkg>
