For Windows User coming to this post, follow these steps:-

You can make sure that pip is up-to-date by running: python -m pip install --upgrade pip

Install virtualenv by running: python -m pip install --user virtualenv

Finally create environment using python -m virtualenv <your env name>

Answer 3

On LMDE2 with :

• Python 3.4.2
• Debian_version : 8.11

It was the first time I use python on this machine and I encountered this problem:

freezed@machine ~/git/repo % python3 -m venv .venv                            
Error: Command '['/home/freezed/git/repo/.venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
zsh: exit 1     python3 -m venv .venv

I solved this problem with :

sudo apt-get install python3.4-venv

Answer 4

Same problem on Linux Mint 17 (which is basically Ubuntu 14.04). Installing python3.4-venv didn't work, so I created virtualenv without pip and then installed pip manually.

1. Create virtualenv and activate it

   python3 -m venv --without-pip foo
   source foo/bin/activate
   

2. Download latest versions of setuptools and pip:

   wget https://pypi.python.org/packages/source/s/setuptools/setuptools-7.0.tar.gz#md5=6245d6752e2ef803c365f560f7f2f940
   wget https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz#md5=01026f87978932060cc86c1dc527903e
   

3. Unpack and install them

   tar xf setuptools-7.0.tar.gz
   tar xf pip-1.5.6.tar.gz
   cd setuptools-7.0
   python setup.py install
   cd ../pip-1.5.6
   python setup.py install
   

Answer 5

I had encountered this issue.

To investigate, I executed the same command as pyvenv did, and then I got "locale.Error: unsupported locale setting".

It finally fixed by configuring "LC_ALL=en_US.UTF-8".

I had below Issues with psutil installation in Ubuntu 16.04 :

Building wheel for psutil (setup.py) ... error

These are my steps which worked:

check your Python version. (My Python version is 3.7)

then done this below addtitional step:

sudo apt-get install python3.7-dev

then

pip install psutil 

source ./my_venv_dir/bin/activate

pip install --upgrade pip
