RStudio is no longer working on my MacBook Pro (running OS 10.14). R itself works. RStudio launches but then fails to do anything more: I cannot open existing files, or open a new file. RStudio was previously working. I had not used it for a while, and it's possible that my OS has been updated since the last time it was working.
I have tried several troubleshooting steps suggested on the RStudio website:
• Deleting startup files (.RData, etc.)
• Verified that I have read and write permissions on RStudio and .rstudio-desktop
• I have done clean installs of RStudio three times with no success.
I was not able to verify the search path: typing the suggested command
into Terminal generates the error message
-bash: syntax error near unexpected token `"R"'
