I installed pip 3.4 recently , however i cant seem to use pip properly ( which is included with the latest python 3) it gives me this error whenever i attempt to import it :
"Traceback (most recent call last)

If you are using python under WIN OS, pip works as a WIN command: try to directly type "pip install .package." in your cmd shell.

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
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.
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:

Installed Twilio successfully however when I attempt to import it in either the shell or terminal I get this error output:
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>

from .util import (
File "/Library/Python/2.7/site-packages/twilio/rest/resources/util.py", line 5, in <module>
import pytz
ImportError: No module named pytz
Can anyone explain what is happening here? My version of Python is 2.7.9 and my pip installer is current as well. Output Error above is from importing in IDLE shell.
Twilio developer evangelist here.
The Twilio library requires pytz to be installed. Easiest way to get it installed is by running this on your terminal:
pip install pytz
Hope this helps

I've followed the install instructions as best I can but can't seem to get past this.
Use this link to install pip properly How do I install pip on Windows?
then do the pip install pylint
then do go through this note http://docs.pylint.org/installation.html#note-for-windows-users
