Anyone please help..
How can I fix the following error:
dyld: Library not loaded: /usr/local/lib/libgdbm.4.dylib
Referenced from: /usr/local/bin/zsh
Reason: image not found
Simple reinstall zsh will help you:
brew reinstall zsh && brew unlink zsh && brew link zsh
Alternatively you can try to upgrade zsh
brew upgrade zsh
Late to the party on this one, but simply running
brew upgrade zsh
solved my issue on MacOS High Sierra. Trying to uninstall gdbm will throw dependency errors against zsh and python, and re-doing the symlinks didn't solve for me, either
I suspect you are running into problems while working with Homebrew on MacOSX. I am actually saying this because I have just run into the exact same situation.
The problem comes after upgrading my MacOSX version to Maverick from Mountain Lion while having already installed Homebrew (of course this may apply to previous and future upgrades). After the upgrade you will need also:
- Reinstall the XCode tools
Run an update on Homebrew
brew update
Run a general upgrade of your Homebrew packages
brew upgrade
Make sure you do not have any other problems on your installation
brew doctor
Finally you may find that certain packages are failing due to missing libraries, which seems to be the case you are describing. The idea here is to reinstall the library missing using the brew command.
In your case you would need to reinstall the gdbm library by performing the next steps on your terminal:
brew uninstall gdbm
brew install gdbm
That should fix it.
To be able to fix my terminal/iterm2/hyper (all were broke because of broken zsh) I had to first change my terminal settings 'Shells open with' from a custom command to the default login shell.
Without these changes, I could not type anything in terminal and iterm2 and hyper were crashing immediately after start.
With these changes, I was able to update my zsh via homebrew as suggested in the other answers by De_Vano and C.Nivs and all three apps worked as expected again. In my case a simple upgrade of zsh was enough. No need to reinstall and unlink.
After searching for a long time, this solved it for me:
brew reinstall ncurses
I had the same issue and did not have an option to change the terminal on startup.
I ended up doing the following steps to resolve the problem:
Create a new user on my mac & enable remote login for him.
Login with the new user, which got a new working shell.
Changing the shell of my original account back to bash, using the chsh command.
Upgrading zsh using brew.
It Worked!
