Cannot connect to MySQL 8.0.11

[chingting]

I updated MySQL to the newest version 8.0.11, but when I tried to connect R to MySQL, it's not working.

Code:
library(RMySQL)
con <- dbConnect(MySQL(), user="hello", password="hi", dbname = "webscrape", host="xx.xxx.xxx.xxx", port=xxxx)

Error:
Error in .local(drv, ...) :
Failed to connect to database: Error: Can't initialize character set unknown (path: compiled_in)

Just ran into this when a homebrew upgrade installed mysql v8.0.11. FWIW, here's what I did to get things working again on my OSX system:

In RStudio, remove the RMySQL package:
remove.packages(“RMySQL")

From a command prompt, remove mysql:
brew uninstall mysql

From a command prompt, install the old version, and keep it from being upgraded in the future:
brew install [email protected]
brew link --force [email protected]
brew pin [email protected]

Back in RStudio, install RMySQL from source:
install.packages("RMySQL", type = "source")
