Updating Composer

The solution is to update Composer to the latest version, which supports the new token format, as suggested by Jordi Boggiano on this tweet. "Composer 1.10.21 and 2.0.12 (both released April 1st) added support for the new GitHub token format."

• Go to getcomposer.org/download/
• Follow the instructions to download the latest phar

The following command will install the latest version of Composer on your machine—v2.2.6 as of this writing. Note that future Composer updates will break the script as shown here, as the sha384 hash check won't pass.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '906a84df04cea2aa72f40b5f787e49f22d4c2f19492ac310e8cba5b96ac8b64115ac402c8cd292b8a03482574915d1a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

Installing composer with brew

You can use Homebrew to install (or reinstall) composer on macOS.

brew install composer

brew reinstall composer

The brute-force fix

2021.04.20

As I mentioned above, both Lukas Kahwe Smith and Jordi Boggiano discouraged tinkering with Composer's auth.json file manually and recommended upgrading Composer to its latest version instead.

Still, here's the brute-force fix that worked for me. Apparently, editing the auth.json is the only way to update to the latest Composer programmatically, and you can revert it to its original state if you opt for this option. The alternative, of course, is to upgrade as shown above.

Edit the composer authentication configuration file ~/.composer/auth.json.

nano ~/.composer/auth.json

Then replace the following.

  "github-oauth": {
    "github.com": "ghp_[YOUR-PERSONAL-TOKEN]"
  }

With this (basic auth):

  "http-basic": {
    "github.com": {
      "username": "[YOUR-GITHUB-USERNAME]",
      "password": "ghp_[YOUR-PERSONAL-TOKEN]"
    }
  }

To Lukas Kahwe Smith and Jordi Boggiano for pointing this out on Twitter.

I found this error while trying to update and install composer packages with composer install.

could not find driver (SQL: select * from information_schema.tables where table_schema = folio_burns and table_name = folio_items and table_type = 'BASE TABLE')

At first, I thought the solution was to edit /etc/php/7.4/cli/php.ini (for PHP-FPM 7.4 in my case) and uncomment the line ;extension=pdo_mysql to be like extension=pdo_mysql . But I was still getting this error as the mysql extension was missing.

PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_mysql' (tried: /usr/lib/php/20190902/pdo_mysql (/usr/lib/php/20190902/pdo_mysql: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/pdo_mysql.so (/usr/lib/php/20190902/pdo_mysql.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

The solution ended up being to install the extension, which would also add its own .ini file and activate itself on installation.

sudo apt-get install -y php7.4-mysql

Note that you can run this command with multiple extensions to be installed at once.

sudo apt-get install -y php7.4-{xml,bcmath,gd,mbstring,xsl,zip,curl,mysql}
