Installation path

composer installation path https://getcomposer.org/download/

Installation under Windows

After the composer is successfully installed in windows, the composer.phar file will be generated in the C:\ProgramData\ComposerSetup\bin path.

Could not input open file: composer.phar appears during use. You should check the composer installation directory and environment variable configuration.

Actual operation

Before you need to execute the composer command, you can copy the composer.phar file to the project file and then execute it

So what we want Take the installation of Yii2-admin extension as an example https://github.com/mdmsoft/yii2-admin. We only need to copy composer.phar to the Yii2 project directory, then switch the command line to this directory and execute

php composer.phar require mdmsoft/yii2-admin "~1.0"

The sign of completion is that the vendor adds the mdmsoft source folder, which is the source file of yii2-admin.

The following are the relevant nodes of composer.json

"require": {
        "php": ">=5.4.0",
        "yiisoft/yii2": "*",
        "yiisoft/yii2-bootstrap": "*",
        "yiisoft/yii2-swiftmailer": "*",
        "guzzlehttp/guzzle": "~5.0",
        "mdmsoft/yii2-admin": "~1.0"
    },
