Composer (composer) installation php-ml

At first I was using the up5.6 version of the PHP command installation composer

Later when using composer, the command line was found to prompt PHP version too low

So I downloaded the wamp and reinstalled the composer with version 7.1 PHP because the PHP-ML requirement must be version 7.1

There are some problems with the installation, that is, the installation is unsuccessful, and there is no folder that appears

When installing with composer, use the path where the Composer.json is located

Usecomposer require php-ai/php-ml

Installation of PHP-ML, but no success, prompt for errors

This is because version matching is not ignored

First set composer to domestic mirror

Composer Config-g Repo.packagist composer https://packagist.phpcomposer.com

Then use the Ignore version matching command

Composer Install--ignore-platform-reqs

You can find the Vendor folder at the Php-ml directory, which is all the library files

At this point, complete the composer install PHP package process

Add: Actually this is not used when I install PHP-ML

About the update command

Composer Update--ignore-platform-reqs

If prompted for warning:

is isn't writable.  Proceeding without cache

This is the execution of composer in the virtual machine, that the directory does not have writable permissions, composer cannot cache the downloaded package, so that each time you have to re-download, the directory is changed to writable readable.
