I am new to python and I switched from Jyputer Notebook working environment to python console (python 3.8.1 shell). I am facing issue in installing packages which I was able to install/import through notebook.
pip install dask
pip install pyodbc
pip install pysftp
pip install selenium
e.g:
>>> pip install pysftp
SyntaxError: invalid syntax
>>>
>>> pip install selenium
SyntaxError: invalid syntax
>>>
While import is working for some libraries.
>>> import csv
is ok
>>> import pysftp
Traceback (most recent call last):
File "<pyshell#44>", line 1, in <module>
import pysftp
ModuleNotFoundError: No module named 'pysftp'

Pip is a utility run from your regular terminal, not a python library so it works outside of a python shell
To install a python package, open your cmd (windows) or gnome terminal(linux):
pip install <package-name>
To install a package in your python source code, there is a deprecated method：
import os
os.system("pip install <package-name>")
Installing a pip package within a Jupyter Notebook:
! pip install --user <package>
After I upgraded pip from 8.1.1 to 19.0.1 by running
pip install --upgrade pip
I tried to test the version of pip by running
pip -V
But I got the following error
Traceback (most recent call last):
File "/usr/bin/pip3", line 9, in <module>
from pip import main
ImportError: cannot import name 'main'
I set the python3 and pip3 to be default by putting the following in ~/.bashrc
alias python=python3
alias pip=pip3
My system is ubuntu 16.04
This is a common issue as referenced here : https://github.com/pypa/pip/issues/5221
You are trying to use the pip, which is shipped with the Debian system. You better try to avoid using that pip at any cost.
Please use python3 -m pip install package instead of the system pip which you have in the debian system.
I also recommend using venv - virtual environments for keeping your system environment safe.
I am trying to install something using "python setup.py install" but it shows me this error :-
Traceback (most recent call last):
File "setup.py", line 3, in <module>
from setuptools import setup
ImportError: No module named setuptools
I have installed this missing module using "pip install setuptools". But still it shows me the same error .I have also tried to install this using "sudo apt-get install python-setuptools" but the problem still remains the same. Help me in this issue
If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setuptools, but will need to upgrade to the latest version:
On Linux or macOS:
pip install -U pip setuptools
On Windows:
python -m pip install -U pip setuptools
If you’re using a Python install on Linux that’s managed by the system package manager (e.g “yum”, “apt-get” etc…), and you want to use the system package manager to install or upgrade pip, then see link

Any ideas?
You can instead use the mysqlclient package as a drop-in replacement for MySQL-python. It is a fork of MySQL-python with added support for Python 3.
I had luck with simply
pip install mysqlclient
in my python3.4 virtualenv after
sudo apt-get install python3-dev libmysqlclient-dev
which is obviously specific to ubuntu/debian, but I just wanted to share my success :)
In Python 3, ConfigParser has been renamed to configparser for PEP 8 compliance. It looks like the package you are installing does not support Python 3.
Here is a code that should work in both Python 2.x and 3.x
Obviously you will need the six module, but it's almost impossible to write modules that work in both versions without six.
try:
import configparser
except:
from six.moves import configparser
pip install configparser
sudo cp /usr/lib/python3.6/configparser.py /usr/lib/python3.6/ConfigParser.py
Then try to install the MYSQL-python again.
That Worked for me
MySQL-python is not supported on python3 instead of this you can use mysqlclient
If you are on fedora/centos/Red Hat install following package
yum install python3-devel
pip install mysqlclient
Additional info:
Python 2x
import ConfigParser
Python 3x
import configparser
Compatibility of Python 2/3 for configparser can be solved simply by six library
from six.moves import configparser
If you are using CentOS, then you need to use
yum install python34-devel.x86_64
yum groupinstall -y 'development tools'
pip3 install mysql-connector
pip install mysqlclient
I was having the same problem. Turns out, I needed to install python3 devel on my centos. First, you need to search for the package that is compatible with your system.
yum search python3 | grep devel
Then, install the package as:
yum install -y python3-devel.x86_64
Then, install mysqlclient from pip
pip install mysqlclient
Do pip3 install PyMySQL and then pip3 install mysqlclient.
Worked for me
I got further with Valeres answer:
pip install configparser
sudo cp /usr/lib/python3.6/configparser.py /usr/lib/python3.6/ConfigParser.py
Then try to install the MYSQL-python again. That Worked for me
I would suggest to link the file instead of copy it. It is save to update. I linked the file to /usr/lib/python3/ directory.
For me the following command worked:
sudo python3 -m pip install mysql-connector
Try this solution which worked fine for me.
Basically it's to reinstall/upgrade to latest version of mysql from brew, and then installing mysqlclient or MySQL-Python from global pip3 instead of virtualenv pip3.
Then accessing the virtualenv and successfully install mysqlclient or MySQL-Python.
I still have this issue, so I go to /usr/lib/python3.8 and type as sudoer:
cp configparser.py ConfigParser.py
You may have another python version than 3.8.
Following #MaciejNg I tried making a copy, which didn't work:
sudo cp ./env/lib/python3.8/site-packages/configparser.py ./env/lib/python3.8/site-packages/ConfigParser.py
Because configparser.py and ConfigParser.py are identical, I renamed the file:
sudo mv ./env/lib/python3.8/site-packages/configparser.py ./env/lib/python3.8/site-packages/ConfigParser.py
how about checking the version of Python you are using first.
import six
if six.PY2:
import ConfigParser as configparser
else:
import configparser
I run kali linux- Rolling and I came across this problem ,when I tried running cupp.py in the terminal, after updating to python 3.6.0. After some research and trial I found that changing ConfigParser to configparser worked for me but then I came across another issue.
config = configparser.configparser()
AttributeError: module 'configparser' has no attribute 'configparser'
After a bit more research I realised that for python 3 ConfigParser is changed to configparser but note that it has an attribute ConfigParser().
I was getting the same error on Mac OS 10, Python 3.7.6 & Django 2.2.7. I want to use this opportunity to share what worked for me after trying out numerous solutions.
Steps
Installed Connector/Python 8.0.20 for Mac OS from link
Copy current dependencies into requirements.txt file, deactivated the current virtual env, and deleted it using;
create the file if not already created with; touch requirements.txt
copy dependency to file; python -m pip3 freeze > requirements.txt
deactivate and delete current virtual env; deactivate && rm -rf <virtual-env-name>
Created another virtual env and activated it using; python -m venv <virtual-env-name> && source <virtual-env-name>/bin/activate
Install previous dependencies using; python -m pip3 install -r requirements.txt
base on your OS is centos use python3
if you don't known where is configparser.py or ConfigParser.py
pip3 install configparser
find / -name "configparser.py"
cd /usr/local/lib/python3.6/site-packages(base on your environment )
cp configparser.py ConfigParser.py
solved the issue
Kindly to see what is /usr/bin/python pointing to
if it is pointing to python3 or higher change to python2.7
This should solve the issue.
I was getting install error for all the python packages. Abe Karplus's solution & discussion gave me the hint as to what could be the problem.
Then I recalled that I had manually changed the /usr/bin/python from python2.7 to /usr/bin/python3.5, which actually was causing the issue. Once I reverted the same. It got solved.
This worked for me
cp /usr/local/lib/python3.5/configparser.py /usr/local/lib/python3.5/ConfigParser.py
I'm having a strange problem while trying to install the Python library zenlib, using its setup.py file. When I run the setup.py file, I get an import error, saying
ImportError: No module named Cython.Distutils`
but I do have such a module, and I can import it on the python command line without any trouble. Why might I be getting this import error?
I think that the problem may have to do with the fact that I am using Enthought Python Distribution, which I installed right beforehand, rather than using the Python 2.7 that came with Ubuntu 12.04.
More background:
Here's exactly what I get when trying to run setup.py:
enwe101#enwe101-PCL:~/zenlib/src$ sudo python setup.py install
Traceback (most recent call last):
File "setup.py", line 4, in <module>
from Cython.Distutils import build_ext
ImportError: No module named Cython.Distutils
But it works from the command line:
>>> from Cython.Distutils import build_ext
>>>
>>> from fake.package import noexist
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named fake.package
Note the first import worked and the second throws an error. Compare this to the first few lines of setup.py:
#from distutils.core import setup
from setuptools import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
import os.path
I made sure that the Enthought Python Distribution and not the python that came with Ubuntu is what is run by default by prepending my bash $PATH environment variable by editing ~/.bashrc, adding this as the last line:
export PATH=/usr/local/epd/bin:$PATH
and indeed which python spits out /usr/local/epd/bin/python... not knowing what else to try, I went into my site packages directory, (/usr/local/epd/lib/python2.7/site-packages) and give full permissions (r,w,x) to Cython, Distutils, build_ext.py, and the __init__.py files. Probably silly to try, and it changed nothing.
Can't think of what to try next!? Any ideas?
Install Cython:
pip install cython
Your sudo is not getting the right python. This is a known behaviour of sudo in Ubuntu. See this question for more info. You need to make sure that sudo calls the right python, either by using the full path:
sudo /usr/local/epd/bin/python setup.py install
or by doing the following (in bash):
alias sudo='sudo env PATH=$PATH'
sudo python setup.py install
For python3 use
sudo apt-get install cython3
For python2 use
sudo apt-get install cython
Details can be read at this
Run
which python
Thats the path to the python that your system has defaulted too
then go to #tiago's method of:
sudo <output of which python> setup.py install
I only got one advice for you : Create a virtualenv. This will ensure you have only one version of python and all your packages installed locally (and not on your entire system).
Should be one of the solutions.
In the CLI-python, import sys and look what's inside sys.path
Then try to use export PYTHONPATH=whatyougot
Running the following commands resolved the issue for me in ubuntu 14.04:
sudo apt-get install python-dev
sudo apt-get install libusb-1.0-0-dev
sudo apt-get install libsystemd-daemon-dev
sudo pip install cython
This link helped me: https://github.com/trezor/python-trezor/issues/40
Ran into this again in modern times. The solution was simple:
pip uninstall cython && pip install cython
Read like a thousand of these threads and finally got it for Python 3. (replace pip with pip3 if you have that kind of installation, and run pip uninstall cython if you have tried other solutions before running any of these)
Mac:
brew install cython
pip install --upgrade cython
Ubuntu
sudo apt-get install cython3 python-dev
pip install --upgrade cython
Windows (must have conda, and MinGW already in path)
conda install cython
conda install --upgrade cython
That is easy.
You could try install cython package first.
It will upgrade your easy_install built in python.
I had dependency from third party library on Cython, didn't manage to build the project on Travis due to the ImportError. In case someone needs it - before installing requirements.txt run this command:
pip install Cython --install-option="--no-cython-compile"
Installing GCC also might help.
Just install Cython from
http://cython.org/#download
and install it using this command
sudo python setup.py install
Then run the command
sudo python -c 'import Cython.Distutils'
and it will be installed and the error message will disappear.
