I am not sure what is wrong but I can't seem to get python3 in a virtualenv environment. I tried upgrading my ubuntu and updating all the packages - but no luck:
python3 -m virtualenv ENV
Running virtualenv with interpreter /usr/bin/python2
New python executable in /home/ramin/projects/buybulkamerica/ENV/bin/python2
Also creating executable in /home/ramin/projects/buybulkamerica/ENV/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
What can I do to ensure that virtualenv installs python3 instead of python2?
First, uninstall existing virtualenv.
sudo apt-get remove --purge python-virtualenv if you installed it using a package manager.
pip uninstall virtualenv if you have installed it using pip.
pip3 uninstall virtualenv if you have installed it using pip3.
Any one of the above commands will work.
Now install virtualenv again. Since you want python3, you need to run the following command.
pip3 install virtualenv
That should do the trick. Now when you create a new virtualenv, it will use python3.
There may be a better way but I had the same problem and after not finding any solution I tried this and it worked.
After you have installed virtualenv using pip, it doesn't matter if you used pip or pip3 if you give the location of your python3 installation to the virtualenv command, like this.
Create new virtualenv
virtualenv --python=/usr/bin/python3.6 environmentname
Access virtualenv
source /environmentname/bin/activate
If this doesn't work, use complete path from pwd
source /complete/path/to/environmentname/bin/activate
Stop virtualenv
deactivate

I am using a old ubuntu so apt install python3.8 will not work. system default python is 3.5.
Then I build python3.8 successfully and run sudo make install. but when I try pip3 install package-name, it still point to python3.5.
I know use python3.8 -m pip install package-name works but I would like to change pip3 to point to new python version directly.
Is it's possible, please help direct me how to do it!
I am trying to install xlrd to read Excel files in python.
I have tried this: pip install -U pip setuptools. My macOS Mojave 10.4.3 has Python 2.7 which is where the default install goes to. But I have also installed Python3.7. How do I get pip install to my 3.7 directory?
I am on Mac machine(Catalina -version 10.15.5) and below pip3 command worked for me.
pip3 install xlrd
python version : 3.7.6
OS : Mac-Catalina(10.15.5)
Thanks to #Tapan Hegde, pip3 install xlrd worked from me, after installing the pip3, like this:
sudo apt update
apt install python3-pip
pip3 install xlrd
I reckon the easiest/cleanest solution would be to use a tool that isolates your python environment, such as virtualenv
Once installed, create a virtual env by specifying which version of python you want to use:
$> virtualenv -p python3 env
Note: puttin python3 directly works only for mac, with linux, you must specify the absolute path or your python binary.
And then 'activate' your environment:
$> source env/bin/activate
From here, any python or pip command you use will use python3.
$> pip install xlrd
Virtualenv has the advantage of not 'polluting' your local python installation, your can manage your pip modules installed more easily.
If you want more detail on how it works and the other alternatives, check this post
When pip install xlrd not work and in computer is still old version, then try do it with current version, for example pip install xlrd==2.0.1.
The current versions are here
I have python in ConEMu loaded and am trying to creating a virtual environment to work in.
I used
pip3 install virtualenv --user
and it said that virtualenv was usccessfully installed, however then I try to
virtualenv .venv
and i get the error message
bash: virtualenv: command not found
wondering if anyone else has run into this problem
virtualenv is built into python 3, and called venv. You don't need to install anything with pip.
You can make a virtualenv in python 3 like this:
python3 -m venv ve
I'm trying to install packages for my python 3.5.0 versus my python 3.4.3
I can run both by typing either python3.4 or python3.5
I have pip2 and pip3. I also ran the script sudo easy_install3 pip, which made me be able to use pip3.4 But I am still having trouble installing modules for python3.5. pip3 just installs for python3.4
I am looking to install termcolor for python3.5 and I am having no success. Can anyone help?
I am on Windows, and you appear not to be, but maybe the following will help.
If pip is in your system's equivalent of python35/Lib/site-packages, then python3.5 -m pip should run pip so that it installs into the 3.5 site-packages.
If you do not have pip in the 3.5 site-packages, copy its directory, along with its dependencies (pip....dist-info/, setuptools/, setuptools....dist-info/, and easyinstall.py) from the 3.4 site_packages.
Or, if pip3 or even pip3.4 is in python35/Scripts, run it with its full path name so you are not running the 3.4 version.
So I've got a virtualenv I've created using pyvenv-3.3, which I thought set up pip to install things into the virtualenv's path. However, I get the following outputs after I've activated by virtualenv:
$ pip --version
pip 1.4.1 from /usr/local/lib/python2.7/site-packages/pip-1.4.1-py2.7.egg (python 2.7)
pip-3.3 --version
pip 1.4.1 from /usr/local/lib/python3.3/site-packages/pip-1.4.1-py3.3.egg (python 3.3)
This is all fine and good, but then my sys.path is this:
['',
'/usr/local/Cellar/python3/3.3.2/Frameworks/Python.framework/Versions/3.3/lib/python33.zip',
'/usr/local/Cellar/python3/3.3.2/Frameworks/Python.framework/Versions/3.3/lib/python3.3',
'/usr/local/Cellar/python3/3.3.2/Frameworks/Python.framework/Versions/3.3/lib/python3.3/plat-darwin',
'/usr/local/Cellar/python3/3.3.2/Frameworks/Python.framework/Versions/3.3/lib/python3.3/lib-dynload',
'/Users/alexgolec/Documents/gutenberg/virtualenv/lib/python3.3/site-packages']
Most notably, the whole site-packages directory is outright missing. Furthermore, this output indicates to me that I'm probably using a python that installed through homebrew at some point. Most infuriatingly, none of the directories in my sys.path are compatible with pip.
Any thoughts on remedies? I won't manually edit my sys.path, but maybe there's some configuration with pip I can do?
Install virtualenvwrapper (makes using virtualenv so much easier):
pip install virtualenvwrapper
.. and then try this:
mkvirtualenv <your_env> -p /usr/local/bin/python3
Where homebrew sticks python is different from where your system has it. You can run the following to see what I'm talking about:
which python
which python3
