Error Installing libraries for a HMC5883L

Question

I am using a HMC5883L for my Raspberry Pi and I am following this tutorial. But after I create the setup.env and enter ../quick2wire.env it shows this error bash: ../quick2wire.env: No such file or directory I know that this means that the file wasn't found but I have followed all the steps in the tutorial so I don't know why I am gettings this error. If anyone knows another tutorial for a HMC5883L or how to fix this error I would really appreciate the help.

This is board that I am using https://www.amazon.com/gp/product/B00SDTFI1Q/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

and the reference link is in the comments because I cannot put three links in (the documentation is at the bottom in the Download and Documentation)

Thank you for your time

Edit:

PWD prints home/pi/Desktop/Compass

and ls -l prints total 8 drwxr-xr-x 7 pi pi 4096 Sep 12 00:42 code -rw-r--r-- 1 pi pi 101 Sep 12 00:42 setup.env

Answer 1

The tutorial says:

. ./quick2wire.env

but it seems it should be saying:

. ./setup.env

NOTE: There is a space between the 2 periods (.)

All that is doing is adding the code (or whatever you named it) directory to your path so that Python can find the libraries it needs when you import ...

As these environment changes are for the life of the session only, you'll need to run that command each time you log in to your Raspberry Pi. A easier/more permanent solution is to add those 2 lines from the setup.env file to the end of your .bashrc file (in your home directory)

You should be able to check that they are set correctly with

env | grep code

[where 'code' is the name of the directory you have the git code in]
