What should I do if composer installation dependencies are slow?

The following tutorial column of composer will introduce to you the solution to the slow installation dependency of composer, and check the detailed execution log of composer. I hope it will be helpful to friends in need!

composer installation dependencies are slow, check composer’s detailed execution log

Installing composer dependencies on windows WSL

composer install

It was found that the execution was abnormally slow. It was suspected that the domestic mirror was not used, but github was directly accessed.

Need to see composer’s execution log

composer -h

I found that composer’s parameters support

 -v|vv|vvv, --verbose           Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

So

composer -vvv install

As expected, they all went to github. . .

After I updated to the domestic mirror source of https://laravel-china.org/composer, I found that the installation was still done through github.

After checking, it turned out to be a problem with composer.lock. Delete composer.lock and run composer install to regenerate it. The reason is that composer.lock caches the previous configuration information, causing the new image configuration to be invalid.
