The error message: “you don’t have write permissions for the \/Library\/Ruby\/Gems\/2.6.0 directory” <\/strong>usually appears on macOS when trying to install a Ruby gem globally using the system Ruby, which is protected by macOS for security reasons<\/strong>.<\/em><\/span><\/h3>\n

\ud83d\udd27 How to Fix It<\/strong><\/span><\/h3>\n

You have several options depending on what you’re comfortable with. Here are the safest and most common solutions:<\/p>\n

\n

\u2705 Option 1: Use sudo<\/code> (Not recommended for general use)<\/span><\/h3>\n

You can prepend sudo<\/code> to your command to gain temporary admin rights:<\/p>\n

\n
sudo gem install <gem_name>
\n<\/code><\/div>\n<\/div>\n

However, this is not recommended<\/strong> long-term because:<\/p>\n

    \n
  • \n

    It modifies system files<\/p>\n<\/li>\n

  • \n

    It can break macOS updates or system tools<\/p>\n<\/li>\n<\/ul>\n

    \n

    \u2705 Option 2: Use a Ruby version manager (Recommended)<\/span><\/h3>\n

    Using a version manager like rbenv<\/strong> or RVM<\/strong> allows you to manage and install gems without touching the system Ruby.<\/p>\n

    \ud83d\udce6 Install rbenv<\/code> (with Homebrew):<\/h4>\n
    \n
    brew install rbenv ruby-build
    \nrbenv install 3.2.2 # or your desired version<\/span>
    \nrbenv global 3.2.2
    \n<\/code><\/div>\n<\/div>\n

    Then install your gem:<\/p>\n

    \n
    gem install <gem_name>
    \n<\/code><\/div>\n<\/div>\n

    This installs everything in your user space<\/strong>, avoiding permission issues.<\/p>\n

    \"you<\/p>\n

    \n

    \u2705 Option 3: Install gems to user space with --user-install<\/code><\/span><\/h3>\n

    If you only want a quick fix:<\/p>\n

    \n
    gem install <gem_name> --user-install
    \n<\/code><\/div>\n<\/div>\n

    Your gems will be installed to:<\/p>\n

    \n
    ~\/.gem\/ruby<\/span>\/2.6.0\/<\/span>
    \n<\/code><\/div>\n<\/div>\n

    To use these gems from the command line, add this to your ~\/.zshrc<\/code> or ~\/.bash_profile<\/code>:<\/p>\n

    \n
    export<\/span> PATH=\"$HOME<\/span><\/span>\/.gem\/ruby\/2.6.0\/bin:$PATH<\/span>\"
    \n<\/code><\/div>\n<\/div>\n

    Then restart your terminal or run source ~\/.zshrc<\/code>.<\/p>\n

    \n

    \ud83d\udee1\ufe0f Final Note:<\/span><\/h2>\n

    Modifying system Ruby can lead to unintended consequences on macOS. Using a version manager is the safest and most flexible long-term solution.<\/p>\n","protected":false},"excerpt":{"rendered":"
