What is the question?
when I wanna add this package, this problem will show up.
Actually I have tried some method, but only reintallation works.
It seems like the actual error message is missing? Can you maybe post which error you get. From you question, it looks like the package was already installed, that’s why it will not do anything.
update ReservoirComputing if you want a newer version. Or you could explicit define which version you want with
Thanks.I have tried to remove the package and add it again, but it does not work.
I have solved the problem.The answer is reinstall julia.
