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.
