Solving the "Library not loaded" Error in PostgreSQL
So, you just installed PostgreSQL using Homebrew and you're excited to get started. But as soon as you type in the command
psql, you hit a roadblock. Error message "dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.6.2.dylib" appears, leaving you clueless. Don't worry, we're here to help! 👩💻🚀
Understanding the Error
Let's break down the error message to better understand what's going wrong:
dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.6.2.dylib
This error usually occurs when the required library file,
libreadline.6.2.dylib, is missing or not correctly linked.
There are a few common causes behind this issue:
Missing or Incompatible Readline Library: PostgreSQL relies on the Readline library, and it seems it can't find the required version (
libreadline.6.2.dylib) in the specified directory.
Incomplete Installation: It's possible that the PostgreSQL installation process encountered an error or wasn't completed correctly.
Outdated or Incorrect Paths: Your system might have outdated or incorrect paths set up for PostgreSQL or the Readline library.
To get PostgreSQL up and running without the "Library not loaded" error, try these solutions:
1. Reinstall PostgreSQL
Sometimes, a fresh installation can solve the problem. Follow these steps:
Uninstall PostgreSQL: Run
brew uninstall postgresqlto ensure a clean slate.
Perform Cleanup: Run
brew cleanupto remove any leftover files from the previous installation.
Reinstall PostgreSQL: Run
brew install postgresqlto install PostgreSQL again.
After reinstalling, run
psql command and cross your fingers 🤞.
2. Reinstall Readline Library
If the Readline library is missing or incompatible, try reinstalling it:
Uninstall Readline: Run
brew uninstall readline.
Clean Up: Run
brew cleanupto remove any remaining files.
Reinstall Readline: Run
brew install readline.
Once the installation is complete, give
psql a whirl and see if it resolves the error.
3. Update Paths
Updating your system's paths can help PostgreSQL locate the required libraries. Follow these steps:
Open your shell's configuration file (e.g.,
Add the following line to the file:
Save the file and close it.
