Let’s briefly talk about the difference between composer update and composer install: Here is the mechanism of composer. When the `composer.lock` file exists, when the `composer install` command is executed , composer will update and install according to the specified version of the package in `composer.lock`. If `composer update` is executed, the `package` version will be updated, and the `composer.lock` file will be updated (I don’t understand the difference, Refer to Zhihu).

The recommended acceleration method in composer China is to replace the default foreign image with a domestic one.

Specific steps:

composer config repo.packagist composer https://packagist.phpcomposer.com

This command is to modify the config.json configuration

 "repositories": {
        "packagist": {

            "url": "https://packagist.phpcomposer.com"
