I downloaded and installed python3.3 from the website and followed the instructions in the readme file.
I can run python3.3 from commandline, but when I try to install a package with pip, it will install to the default python (Anaconda python 3.6 in my case).
I tried installing a new pip using easy_install as described
here, but it gives me the error saying
/usr/local/bin/python3.3: No module named easy_install
How can I install the setuptools if I don't have pip?
Does your Anaconda distribution (Python 3.6) have pip installed already? If yes, you can use virtualenv as virtual environment.
Check if you have virtualenv installed. In my computer, I have virtualenv 16.0.0 installed.
$ virtualenv --version
16.0.0
If it says, "command not found", you can install virtualenv.
$ pip3 install virtualenv
Once virtualenv is installed, create a new virtual environment, with Python 3.3. In the command below, we will create a new virtual environment called venv, that uses Python 3.3.
$ virtualenv --python=/usr/bin/python3.3 <path/to/new/virtualenv/> venv
If it says the path does not exist, check the path to python 3.3 using which command.
$ which python3.3
Activate the the virtual environment venv. The commands are activate to activate and deactivate to deactivate.
$ source venv/bin/activate
Install the package that you want.
$ pip3 install X
Once you are done and what to use the default Python 3.6, deactivate the virtual environment.
@aeduG's answer is correct. Alternatively, you can use virtualenv. See here for the differences between conda virtual environment and virtualenv.
See here if you want to use conda's virtual environment instead.
