I've recently installed pylint on a windows 7 and when I run it I get the error:
Error executing PyLint: Command failed with error=None, status=1; stderr:

I Have followed the below steps for airflow installation and have successfully installed but am unable to run any commands which start with airflow, even to check the version. Any help is appreciated.
python3.9 -m venv airflowenv ,
source airflowenv/bin/activate export ,
AIRFLOW_HOME=~/airflow ,
echo $AIRFLOW_HOME ,
pip install --upgrade pip ,
pip install apache-airflow==1.10.15 ,
airflow initdb.
This is the error am receiving:

---------------------------------------------------------------------*********************************************************************
SOLUTION:[Followed these steps to fix the issue]:
Install python3.9 from the python website
python3.9 -m venv envpython
source envpython/bin/activate
export AIRFLOW_HOME=~/airflow
echo $AIRFLOW_HOME
pip install apache-airflow==1.10.15 --constraint https://raw.githubusercontent.com/apache/airflow/constraints-1.10.15/constraints-3.8.txt
airflow initdb
airflow webserver
airflow scheduler
*********************************************************************
If you are on MacOS, you need to install Python 3.8 manually following https://www.python.org/downloads/.
See Import issue for setproctitle on Mac OS,
You should use constraints when installing Airflow. See this link that explains why: https://airflow.apache.org/docs/apache-airflow/stable/installation.html#constraints-files
In your case, the correct command will be:
pip install apache-airflow==1.10.15 --constraint https://raw.githubusercontent.com/apache/airflow/constraints-1.10.15/constraints-3.8.txt
I'm getting these errors while working with Spyder and Anaconda. My Python scripts only work with the Anaconda prompt and nothing else is working. This is the whole error:

I even uninstalled and installed zmq but the error persists.
Try
pip uninstall pyzmq
pip install pyzmq
#CanciuCostin's answer is correct, but for doing something slightly different worked:
pip uninstall pyzmq
pip install --user pyzmq
HTH.
Good morning!
Until yesterday I was using python 2.7 and using the following code for writing output files for my scripts:
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
But now I'm upgrading my code to python 3.7, so now I need to use importlib.reloadinstead of just reload. However, typing sudo -H pip3 install importlib on my shell gives me the following error:
Collecting importlib
Using cached https://files.pythonhosted.org/packages/31/77/3781f65cafe55480b56914def99022a5d2965a4bb269655c89ef2f1de3cd/importlib-1.0.4.zip

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-install-3cz_3d6n/importlib/
After looking for solutions I also tried to upgrade setuptools, but that didn't fix my problem.
Many thanks in advance!
importlib at PyPI is an outdated package intended for very old Python versions. For new versions of Python importlib is a module from the standard library, you don't need to install it, it's always available.

pip install -r requirements.txt
And then re execute elastalert.
I am trying to install spacy for windows, python 3.x.
I ran the following commands:-
conda install -c conda-forge spacy
python -m spacy download en
"python -m spacy download en" gives the error:-

and the same error when I try to import spacy thereafter. What should I do to successfully install spacy?
I found this link from where I downloaded all of the required whls one by one to install spacy.
Compiling wheel rather than downloading ready one might be helpful as well:
python -m pip install thinc --no-binary=:all:
or
pip install thinc --no-binary=:all:
Don't forget to add --force option if you already have the package.
More information about --no-binary option:
