Britain is required in order to run eBay a service obligation without Dwarka.
And then this last, or I'll demonstrate you how to verify installation of the python on Marcos computer
and if needed, update it and in the next Loescher.
I'll explain you how to do that on windows.
Also, we will need to install PIB envy that will help us to manage Python virtual environments.
Let's get started with the verification of the installation of the python on my ankles, and I'll also
demonstrate you how to update it if needed.
Let's go to the terminal and here in the terminal, please write Python three.
There's this version.
And I see version three, seven, three.
And actually, every Mac also comes with installation of the Python out of the box, but I see that
I have not the latest version and latest version I could verify here at the Python dot org website by
going to download section.
And here I'll see the latest version.
At the moment of the recording of this video is 3.9 or two, and I have one of the previous versions
this way.
Let me update current version to the latest one.
Let me click on download Python 3.9.
The two big file will be downloaded.
Let me open it up.
Continue.
Continue to agree.
Cadena install.
Enter my password and install software.
Python was installed, and it has opened the folder with Python 3.9 automatically.
Let me close it and let me close installer.
Let's move it to.
All right, let me know.
Verify whether a Python 3.9 is available here in the terminal and I still see previous version.
I need to reopen time in order to see a new version.
Let me actually try to open a new tab like that press.
No, I don't want to update on my cell and your type Python three.
Does this version once again?
And now I see it.
Latest version three 9.2 Also, along with Spiderman three, I should see the IP three that is actually
package manager for Python.
And if I type Vibe three, I'll see a bunch of options.
And if I add here does this awesome IOC version of the Play three and it has twenty to 2.3.
It means that I am good to go now and I'm able to use latest version of the Python on this computer
and also accept the Python.
And I need the additional package installed to scold baby envy, and I could verify whether it didn't
start honored by typing vibe.
There's desperation and I see that the command is not found.
No, let's install this additional package globally on this computer, and with this package, baby
in we, we will be able to create Python virtual environments after installation in one of the next
lectures.
I'll explain you why I recommend you to use baby envy for managing Python beautiful moments.
And also, I'll explain what is Python virtual environment for now?
Let's just install this baby in the package.
For that, let's go to Google Chrome Feuilles and here it is in your tab lets type the IBM Ian VM.
And let's click on the link that leads us to buy buy dot org website that the least all available Python
packages.
And here you'll find the sweeps of the Envy package, and you might tweet here that this package automatically
creates and manages virtual environments for your Python projects.
It released all packages in the AP file and also it will generate a B file log file.
All right.
Let's go ahead and install the HP Envy for Mac.
And as any Python package, we could install it with help of pipe that is Python package manager.
If you scroll down to the documentation link here and click on it, you will find actually instructions
how to install the app envy and you'll find three options here with help of you.
Actually, you should use Baby three, the this package installer for the third version of the Python,
and also there was alternative commands to install a PTEN VM.
But as you might read here, this option is now discouraged and you should not use it.
So please use this command instead.
Let's go ahead and using Tap Package Manager, install and weep for a particular user in its home directory.
Let's go to the terminal and here again, instead of B.A.P, please type tap three, then install Yeoville
option does this user and next will be the name of the package baby NBA.
Let's go ahead and install it.
Installation was completed, but I see few warnings, and the first one is here aren't the scripts ABC,
NBC and ABC envy this resolver are installed in this folder.
Here it is, but this folder is not in power.
You might see also all the warnings related to all those sweeps that were just installed.
We'll dispel wealth is an environment variable, and it is a global environment variable Olmec, and
you could read any variable on Mac by entering the comment Echo Dot or sign variable.
And if you type this comment, you'll see current value of this environment variable path.
And you might notice that this folder not in this path.
That's why I will be able to access any script located in this folder globally inside of the command
line by simply entering, for example, envy.
If I enter such command, I'll see error from the Z Shell Shell command not found by any of you.
And this what this warning is all about.
We need to modify path and add this folder to it, and we could do that either temporarily by using
export command here or directly in the terminal or permanently.
If you want to go to the permanently, you need to modify this shell configuration profile.
Please notice that Z Shell is default shell in Catalina and older versions of the macOS.
In previous versions, if you're using older versions, you need to modify best profile instead of Z
cell profile.
Now let me show you how to modify his usual profile on this computer in order to do that.
Please go to a home directory of your user.
I am actually already in the home directory of this user.
This deal, the sign tells me that, but if you are not in the home directory, you could send it to
it by entering Sydney and do the sign like that.
And here a police type alerts this L.A. command.
This command will lease the old files and folders in the home directory of the user.
In my case, this Bogdan user and you should find your hidden file gold dot z cell rc and we need to
modify exactly this file in order to be able to access executable files inside of this folder.
Looking at scroll a bit up inside of this folder.
Let me copy this folder name like that.
Please do so as well on your computer.
You, of course, see another path because your user will be different from mine.
Please copy your path.
Next, let's edit DOT is you sell RC file, and you can do that very easily using content editor that
is built in on Mac.
Simply type now and name of the file.
Dot Z Cell RC.
Like that and you'll find existing configuration file for Z Cell on the second line.
You should see such as export path.
In my case, it is comment that out here, I see this pound sign if in your case, it is not coming
out.
You should modify your export path command and add to it folder that you just copied from the warning.
I will throw uncomment this line like that.
And afterwards, bliss, modify it like that.
Remove this section from hero worship only door sign, pile and paste here.
Go a bit path to the folder that we just copied from as a warning.
And next, please ED column before the assigned path.
This will mean that this command will actually modify existing agbele of the path environment variable
and and to eat this string.
If in your case, in that Z Cell C configuration file, you already see uncommon that export path line.
Please don't delete anything in it and just add prefix to it like this.
No, let's say who changes in this configuration file for that police rescue combination of control.
Then press yes and press enter.
Now you could verify whether changes were applied or not by entering court Dot Z Cell are C command
and scroll up to the very beginning of this file.
And here you should find command export path that looks like this.
All right.
Now all is said and we could try to a law terminal in order to verify wells.
Now we will access EMV executable file.
But before doing that, let me quickly deal a wheels.
One more warning I saw here during installation of the interview.
And here was this warning.
I was told that the paper version is older than last version, and I could very easily update version
of the baby by entering such comment.
I could copy it from a show like that and paste it here and execute.
Babies should be updated right now.
And now the AP abortion 21 does 0.1, in my case was successfully installed.
No, let's go ahead and reload terminal.
In my case, I'm using Item two.
You could probably use terminal application that is built in terminal on calls, but before load of
the terminal, let me go to this four step where I'm still running front and application and terminate
this process by pressing control.
C key combination.
And no lets exit from Item two with terminal.
And now let's open it back again.
And here, let's verify current value of the path variable like that, and I'll see that it was correctly
adjusted as was instructed in the Dot Z cell are a C configuration file and this folder is here in the
path.
Go ahead.
It means that the now I could try to access B.A.P Envy executable file and view and type, for example,
option does this bottom.
And now I see resolved version of the PPE and we installed on this computer is here and now I have access
to the IPAB and executable file.
This concludes installation of all Python tools necessary for development of API service and then the
next lecture.
I'll explain you how to do the same on windows.
How to install Python and API envy.
There are if you are a macOS user, of course.
Feel free to skip next show.
I'll see you soon.
