Understanding the 'Brew Link' Error
The 'Brew Link' error usually occurs when you try to install a software package using Homebrew, a package manager for macOS (and Linux). This error is typically caused by one of the following reasons:
- Permission issues with the target directory
- Conflicting files or symlinks
- Incomplete or interrupted installation process
Step-by-Step Solution
Follow these steps to resolve the 'Brew Link' error:
Step 1: Identify the Error Message
Note the error message displayed during the installation process. It will provide information about the cause of the issue. Examples of common error messages include:
- Permission denied
- File exists
- Symlink points to another file
Step 2: Resolve Permission Issues
Check if you have write permissions for the target directory. Run the following command:

If you don't have write permissions, change the ownership of the target directory using the following command:
sudo chown -R $(whoami) /usr/local/include
Retry the installation process.

Retry the installation process.
