Whenever I try to install packages like: JuliaDB, ExcelReaders, ExcelFiles and SymPy, the program shows this message in the console: GitError (Code: ENOTFOUND, Class: Repository, Could not find repository from ‘DocStringExtensions’)  
What should I do?

Unfortunately it did not work, your solution is for SSL error. I need a solution to this error:  
GitError (Code: ENOTFOUND, Class: Repository, could not find repository from ‘DocStringExtensions’)  
Thanks

Looks like there is a problem with `.julia/v0.6/DocStringExtensions`. You could try to remove that directory and try again.
