preface
Believe for python developers, the machine has different python version is very normal, because the development of the project in 2.6 or 2.7, 3.0 + in some versions, how to put these different versions of management is good, keep the each environment clean and independent, easy to switch between different versions, this time is going to use our virtual environment, so today we take a look at python build tools pyenv using virtual environment.
1, install,
git clone https://github.com/yyuu/pyenv.git ~/.pyenv
echo ' export PYENV_ROOT= " $HOME/.pyenv "' >> ~/.bash_profile
echo ' export PATH= " $PYENV_ROOT/bin:$PATH "' >> ~/.bash_profile
echo ' eval " $(pyenv init -) "' >> ~/.bash_profile
exec $SHELL
source ~/.bash_profile
Just log out and log in again.
2. Common commands
pyenv install, list # lists the installable versions of python
pyenv install -v 3.3.5 # install version 3.3.5
pyenv uninstall 3.3.5 # uninstall
pyenv version # view the current version
pyenv global 3.3.5 # switch to version 3.35
3. Install pyenv-virtualenv
git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
source ~/.bash_profile
4. Create a virtual environment
pyenv virtualenv 2.7.10 env2710
5. Activate the virtual environment
pyenv activate env2710
You can then install the required software in this environment.
6. Quit the virtual environment
pyenv deactivate
