Try
尝试
composer self-update
If this doesn't work check your PATH variable, if it's not there try searching composer.bat in windows and add it to your PATH variable. Normally, its in following path.
如果这不起作用，请检查您的 PATH 变量，如果它不存在，请尝试在 Windows 中搜索 composer.bat 并将其添加到您的 PATH 变量中。通常，它在以下路径中。
C:\ProgramData\ComposerSetup\bin
C:\ProgramData\ComposerSetup\bin

php composer.phar self-update
'update' updates your dependencies not composer itself.
'update' 更新您的依赖项而不是 Composer 本身。
