MacOS – How to make Visual Studio Code run python 2.7.15

macospythonvisual-studio-code

I'm using an iMac with High Sierra. I used Anaconda to install both python 2.7.15 and python 3.6.5. I created virtual environments for both of these. I'm trying to learn python and I'm using Visual Studio Code. I've run scripts fine that were developed for python 3 but the code I'm currently working with was developed for python 2. I can not get VScode to run using a python 2 interpreter, it seems to use python 3 no matter what I do. I could rewrite the script to make it compatible with python 3 but I'd rather not do that. I've tried running VScode from the python 2 virtual environment but that seems to have no effect. I edited the settings in VScode and changed the variable python.pythonPath to point to python 2 but that doesn't work. I used the command pallet to change the python interpreter but that doesn't work either. How do I force VScode to run python 2.

Start VScode and open your python script. Using either the command palette or the status bar, select the python interpreter you wish to use. Both options present a list of available interpreters. Now you may run your code by right-clicking in the edit window and selecting "Run python file in terminal". A terminal window opens below the edit window and your code executes there. Note: You must execute your code using the right-click technique described above. Other methods, such as using the command palette with "run: code", will not work

MacOS – How to install SciPy and VisualPython on OSX Mavericks

When you install Anaconda, it installs a different version of Python, which has SciPy, NumPy, pandas, matplotlib, and whole lot of goodness bundled with it. However, those libraries won't automatically become usable by your other Python version that comes pre-installed on your computer (or any other Python version that you installed yourself).

From the command line, try which python - this will tell you which Python you're using on the command line right now. If what is printed has the word 'Anaconda' in it, you are fine, and you should be able to use scipy. If not, then that is not the right Python associated with scipy.

In your shell configuration file (typically .bashrc or .bash_profile) Anaconda makes the required change to make sure that you start using the Anaconda version of Python. From your output, it seems that it didn't get your username right. In the path, the username should be your actual username on the computer. Try to make that change, restart your terminal or a shell session, and try again. It might also simply be that you never restarted your terminal. Let us know what you find.

MacOS – Installing virtualenvwrapper on macOS Sierra – “-bash: /usr/local/bin/virtualenvwrapper.sh: No such file or directory” error

You have a mix of pythons on your machine. I would stick to one.

In this case I would stick to anaconda.

SO edit your path so that anaconda is first on the path before /usr/local/bin and /usr/bin

Test by running

 which python

You should get

/Users/mark/anaconda3/bin/python

If a 2 rather than 3 you have python2,7 and I would switch to 3.

You can now use virtulenv etc as they are part of python 3.6 (the current 3.x version) see the python docs You should use venv now not what your tutorial shows https://docs.python.org/3/library/venv.html

However as you are using anaconda you can use conda insteaf of venv, You will find most things already installed (I use conda as it provides prebuilt C libraries when needed, pip etc can be more complex and also could require Xcode) https://conda.io/docs/user-guide/getting-started.html The django install is at https://anaconda.org/anaconda/django
