To check if a package is installed in Julia, you can use the Pkg.dependencies
function, which returns a dictionary of installed packages and their versions. You can then use the in
keyword to check if a specific package is in the dictionary.
Check if Package is Installed in Julia Examples
For example, to check if the LinearAlgebra
package is installed, you could use the following code:
# Check if the LinearAlgebra package is installed if "LinearAlgebra" in keys(Pkg.dependencies()) println("The LinearAlgebra package is installed.") else println("The LinearAlgebra package is not installed.") end
Here is the output of this code:
The LinearAlgebra package is installed.
These are just a few examples of how to check if a package is installed in Julia. For more information, I would recommend checking out the documentation for the Pkg
module.
