Problem 1
- topthink/think-installer is locked to version v1.0.11 and an update of this package was not requested.
- topthink/think-installer v1.0.11 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.1.0] but it does not match the constraint.
Problem 2

- topthink/think-testing v1.0.6 requires topthink/think-installer ~1.0 -> satisfiable by topthink/think-installer[v1.0.11].
- topthink/think-testing is locked to version v1.0.6 and an update of this package was not requested.
解决方法
当你遇到这个问题的时候，你要考虑你用的composer.phar版本问题
composer太高了，改成1.0.22版本
composer下载链接: https://getcomposer.org/download/
不要用最新版本，因为上面提示要1.版本所以，2.版本完全不能使用
安装composer
下载后
cp composer.phar /usr/local/bin/composer
查看版本
composer -V
