Note: sudo access is required for this ^__^
As I mentioned in another post, I want to be able to embed Python scripts that use the tk module into my WordPress blog (this website). I started a basic plugin that effectively embeds Python scripts into WordPress posts (yay!) … however I hit a snag when I discovered that my web server does not have the proper dependencies installed to support the code I’m writing. Even as a beginner at Python. D’oh!
Since I’m on a managed hosting platform (DreamHost’s DreamPress) – I don’t have sudo access to install the proper modules with.
Sooooo one of my besties spun me up an Ubuntu Bionic instance (thank you!) on DreamHost’s Cloud hosting platform; DreamCompute…… annnnd since I need Python 3.7 and Bionic comes with 3.6 .. I’m going to go ahead and install Python 3.7 on it … right here, right now.
No one has to know.
Start by logging into your server via SSH as a user with root permissions. If you don’t know how to SSH, you can get started with SSH here. Ultimately, you’ll need to contact your host for login credentials and all that good stuff.
From root, run the following
sudo apt command. This updates the Python package list:
This will look something like this:
sudo apt update
Next, run a
sudo apt install command to install packages needed to build out Python source:
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget
That is going to start out looking something like this:
…and end up looking something like this:
Moving on …. Use
wget to download the latest Python release:
When that completes, extract the tarball (compressed file) with a
tar -xf Python-3.7.3.tar.xz
Then go ahead and navigate into the Python 3.7.3 folder:
Here is what that looks like in my terminal:
Now, we’ll go ahead and run the
configure script which runs a series of checks on all dependencies to confirm that all are present.
--enable-optimizations flag optimizes the Python binary by running further tests. This might slow the build process down a bit.
SWEET! Now let’s start building using
make -j 8
You’ll go into the matrix for a few minutes while this builds. Patience is key here friends, just let it run.
Me to my bestie: I’m in ur DreamCompute, building ur Python…
Me, taking a nap while this builds: =^__^= zzZZZzzZZZzzzZZzzzz
Me eating snacks while this bui…….
……Ok so once it’s done building the success output will look like this:
Next! –>>>> Install the Python binaries with another
sudo make altinstall
If you use a
make install you would override the default system python3 binary. So going with an
altinstall this time….
Back into the matrix we go!
..annnnnd .. Success! We can turn into a pumpkin now because we are done with our install! Woot!
Verify the installation was a success with a
The robots should tell you that you’re running Python 3.7.3!
Heck yeah, us!

Hi, very nice website, cheers!
Thanks, Garth! Much appreciated. 🙂
