mysql-python: Berechtigungstabellen können nicht geöffnet und gesperrt werden: Tabelle 'mysql.host' existiert nicht

Question

Ich habe mysql mit homebrew installiert.

Ich versuche jetzt, mysql-Python zu installieren, und ich bekomme den Fehler unten, wenn ich mysql ausführen.

Ich bin neu in der Programmierung und weiß nicht genug, um das Problem zu identifizieren.

Jede Hilfe wird geschätzt. Vielen Dank.

Ich fand es heraus. Ich habe vergessen, den Anweisungen oben auf den Homebrew-Installationshinweisen im Terminal zu folgen.

Hope spart Zeit für andere, die den gleichen Fehler machen.

Set up databases to run AS YOUR USER ACCOUNT with: 
    unset TMPDIR 
    mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp 

To set up base tables in another folder, or use a different user to run 
mysqld, view the help for mysqld_install_db: 
    mysql_install_db --help 

and view the MySQL documentation: 
    * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html 
    * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html 

To run as, for instance, user "mysql", you may need to `sudo`: 
    sudo mysql_install_db ...options... 

Start mysqld manually with: 
    mysql.server start 

    Note: if this fails, you probably forgot to run the first two steps up above
