Can't update chromedriver in macos10.12.6

Question

I am trying to update chromedriver from 2.30 to 2.35. However, after I brew install chromedriver, the default chromedriver is still 2.30. If I redo brew, it will tell me I have already installed 2.35 version, but when I use chromedriver --version, it still shows 2.30. Can any one tell me why it's that? And can I know where does this brew install?

Thanks!

Output of brew list chromedriver:

/usr/local/Cellar/chromedriver/2.35/bin/chromedriver 
/usr/local/Cellar/chromedriver/2.35/homebrew.mxcl.chromedriv‌​er.plist

and output of which chromedriver shows it's using version 2.30 in other path.

Answer 1

I had the same problem and was able to fix it by:

brew uninstall chromedriver

then I did

brew info chromedriver

which told me to do:

brew tap homebrew/cask
brew cask install chromedriver

It installed chromedriver 2.40

Answer 2

brew cask reinstall chromedriver

In my case helped just reinstalling chromedriver
