Installing Required Packages
The necessary packages must then be installed from source code in order to compile and install Python 3.8. For the creation and installation of Python 3.8, these packages are necessary. Open a terminal window and type the following command to install the required packages:
There are none, really.
Install the build-essential z lib1g, libncurses5, libgdbm, libnss3, libssl,dev libreadline, dev libffi-dev libsqlite3, dev wget curl llvm libbz2-dev -y
Build-essential, a collection of essential packages for creating Ubuntu packages, will be installed in this command, among other packages. While libssl-dev and libreadline-dev are required for Python to compile Python with SSL support, libncurses5-dev, libgdbm-dev. libnss3-dev is libraries that are used by Python. To support various Python modules and to download files from the web, respectively, libffi-dev, libsqlite3-dev wget, curl, llvm, and libbz2-dev are all used.
We can move on to downloading and installing Python 3.8 on Ubuntu once these prerequisites are in place.
## Downloading and Extracting Python 3.8
Python 3.8 download and extracting instructions
Visit the official Python website at [python.org] to download Python 3.8. To begin the download, click "Download Python 3.8.0" under the heading.
Once the download is finished, open a terminal window and navigate to the directory where the downloaded file is. extract the files using the following command:
tar -xf Python-3.8.0.tgz.
The name of the downloaded file should be changed to "Python-3.8.0.tgz."
The files from the downloaded archive can be extracted using the `tar` command. The name of the archive file to extract is specified by the `-x` option, while the `tar` option tells the files to be extracted.
A new directory with the same name as the downloaded file should appear after the extraction is finished. How to compile and install Python 3.8 from source code will be covered in the next section.
## Compiling and Installing Python 3.8
Python 3.8 is Compiled and Installed.
We can compile and install the Python 3.8 source code now that we have extracted and downloaded it. To install and compile Python 3.8 on Ubuntu, adhere to the following instructions:
1. To access the directory where the extracted files are located, open a terminal window. Navigate to the directory using the `cd` command:
There are none, really.
Python-3.8.12: cd
- To configure the installation, run the following command:
There are none, really.
configure –enable-optimizations for./configure
This command prepares the source code for compilation and optimizes the installation for your system's architecture.
3. The source code can be compiled using the following command:
There are none, really.
Make -j `nproc'
The number of threads specified by the nproc command is used to compiles the source code using this command. Compilation can be accelerated by using several threads.
- To install Python 3.8, run the following command after that:
There are none, really.
Make altinstall sudo
Instead of replacing any current Python installations, the `altinstall` option is used to install Python 3.8 alongside any existing Python installations. As a result, any system applications or scripts that rely on the system's default Python version will continue to function properly.
Depending on the hardware of your system, the compilation and installation process might take a few minutes to complete. After the procedure is finished, you can move on to setting up the environment variables to make sure your system can find the Python 3.8 installation.
## Setting up the Environment Variables
Setting up the environment variables that instruct the system on where to find the Python 3.8 installation is necessary if Python3.8 is to be used on Ubuntu.
Subsection 1: Adding the.bashrc File.
When a new terminal window is opened, the.bashrc file is an execution shell script. To guarantee that our system can find the Python 3.8 installation, we can add the necessary environment variables to this file.
Open the terminal and type the following command to edit the.bashrc file:
There are none, really.
The ~/.bashrc for nano is
The.bashrc file in the nano text editor will appear as a result of this command.
Subsection 2: Add the Environment Variables.
Add the following lines to the.bashrc file’s bottom by clicking it:
There are none, really.
export PATH, which is located inusr/local/bin,
exported LD_LIBRARY_PATH=”/usr/local/lib”
The first line adds the /usr/local/bin directory to the PATH environment variable, instructing the system on where to locate the Python 3.8 executable. The second line adds the /usr/local/lib directory to the LD_LIBRARY_PATH environment variable, instructing the system on where to locate the Python 3.8 shared libraries.
Subsection 3: Saving and Applying the Changes
By pressing theCtrl X, then the Y, and the Enter keys, you can save and exit the.bashrc file.
The following command should be used to apply the modifications:
There are none, really.
source: ~/.bashrc
The changes will be applied to the current terminal by this command. We can test the installation to make sure everything is functioning properly after setting up the environment variables.
Testing the Installation
The Installation: Testing the Installation
Verifying that the installation was successful is crucial after Python 3.8 was installed on Ubuntu. You can start developing Python applications on your system by testing the installation to make sure everything is functioning properly.
Open a terminal window and type the following command to test the installation:
``Bash,`.
python3.8 -version
The version number of Python 3.8 should be returned by this command, confirming the installation was successful. refer to the troubleshooting advice provided earlier in this article if you run into any difficulties while installing or when testing the installation.
It's crucial to test any additional tools or packages you've installed for Python development on Ubuntu in addition to testing the Python 3.8 installation itself. By doing this, you can make sure that your development environment is fully functional and prepared for use.
## Troubleshooting Common Errors
Even with the most detailed instructions, it's possible to encounter some common errors during the installation process. Here are some solutions to help troubleshoot these errors:
### Missing Dependencies
If you encounter an error regarding missing dependencies during the installation process, it's important to install them before continuing. To do so, use the following command:
```none
sudo apt-get install <package-name>
Replace <package-name> with the name of the missing package.
Errors During Compiling
If you encounter errors during the compiling process, it’s possible that your system is overloaded with too many processes. To fix this, try running the make command again with fewer processes by replacing -jnproc` with-j 1`.
If you continue to encounter errors during the installation process, refer to the Python documentation or seek assistance from the Python community.
By following these troubleshooting tips, you can overcome common errors and successfully install Python 3.8 on Ubuntu.
