In this article, we will delve into the steps required to force update Meson on Ubuntu 18.04.4 LTS. Meson is a popular build system designed to be user-friendly and efficient. However, keeping it updated is essential to take advantage of its latest features and improvements.
- Step 1: Install Meson Using pip3
- Step 2: Reload Your .profile
- Step 3: Update Your PATH Variable
- Step 4: Check the Meson Version
- Additional Solutions
Before we begin, ensure that you have administrative access to your Ubuntu system and that it’s updated with the latest packages. You can update your system by running the following commands:
sudo apt-get update sudo apt-get upgrade
Step 1: Install Meson Using pip3
The first step is to install the latest version of Meson using pip3. Pip3 is a package installer for Python3. You can install Meson with the following command:
pip3 install --user meson
This command installs the latest version of Meson in your user directory. The
--user flag ensures that Meson is installed locally for the current user, not system-wide.
Step 2: Reload Your .profile
After installing Meson, you need to reload your
.profile file to ensure that the changes take effect. The
.profile file is a script that is executed during startup. You can reload it by running the following command:
This command reads and executes the
.profile file in the current shell session.
Step 3: Update Your PATH Variable
Sometimes, even after installing the latest version of Meson, the system may still use the older version. To fix this, you can update your PATH variable to prioritize the newly installed version. The PATH variable is a list of directories that your shell searches for executable files. You can update it with the following command:
/home/youruser/.local/bin with the actual path to the Meson installation directory. This command adds the path to the newly installed Meson to your PATH variable.
Step 4: Check the Meson Version
To verify that the update was successful, you can check the Meson version. Run the following command:
This command displays the version of Meson that is currently in use. If the update was successful, it should display the latest version that you installed.
If the above steps do not work, consider the following solutions:
Solution 1: Remove the Existing Meson Installation
You can remove the existing Meson installation using the following command:
sudo apt-get remove meson
Then, reinstall the new version with pip3 as explained in Step 1.
Solution 2: Locate the New Version of Meson
You can locate the new version of Meson installed in your Python environment using the
whereis meson command. Then, run the located version directly without affecting the systemwide installation.
Solution 3: Create a Symbolic Link to the New Version
If the scripts still use a hardcoded path to the older version of Meson, you can create a symbolic link to the new version. Use the following command:
sudo ln -si /path/to/new/meson /usr/bin/meson
/path/to/new/meson with the actual path to the new Meson executable. This command creates a symbolic link, which is a type of file that serves as a reference to another file or directory.
Keeping your tools updated is an essential part of system administration. This guide provided a detailed walkthrough on how to force update Meson on Ubuntu 18.04.4 LTS. Remember to adapt the solutions to your specific setup and replace any placeholder paths with the correct ones. Happy coding!
No, the apt package manager does not provide the latest version of Meson. It is recommended to use pip3 to install and update Meson.
The –user flag ensures that Meson is installed locally for the current user, rather than being installed system-wide. This allows you to have multiple versions of Meson installed and easily manage them.
Reloading the .profile file ensures that the changes made during the installation of Meson take effect. The .profile file is read and executed during the startup of each new shell session.
You can check the version of Meson installed on your system by running the command
meson --version. This will display the version number of Meson currently in use.
If the update steps mentioned in the article do not work, you can try removing the existing Meson installation using
sudo apt-get remove meson and then reinstalling it using pip3. Alternatively, you can locate the new version of Meson installed in your Python environment using the
whereis meson command and run it directly.
