Thanks for your suggestion, I have solved the installation problem I encountered when using the command `Pkg.add()`, although I don’t know why it works.  
When I try to reinstall Julia according to the method [here](https://ferrolho.github.io/blog/2019-01-26/how-to-install-julia-on-ubuntu), I found that the last two steps of the installation part I did not do before. So I just added those two commands in the terminal  
`sudo cp -r julia-1.4.2 /opt/`  
`sudo ln -s /opt/julia-1.4.2/bin/julia /usr/local/bin/julia`  
and then it can automatically install the packages I need.
