Minify - Composer安装错误

Question

我尝试在正确的目录中使用composer install从composer.json文件安装，但得到以下错误：

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package scrapbook/psr-cache could not be found in any version, there may be a typo in the package name.
  Problem 2
    - The requested package satooshi/php-coveralls dev-master exists as satooshi/php-coveralls[0.1.0, 0.2.0, 0.3.0, 0.3.1, 0.3.2, 0.4.0, 0.5.0, 1.0.x-dev, 1.1.x-dev, 2.0.x-dev, v0.6.0, v0.6.1, v0.7.0, v0.7.1, v1.0.0, v1.0.1, v1.0.2, v1.1.0, v2.0.0] but these are rejected by your constraint.

Answer 1

您遇到了一些问题：

1)包列表中没有任何名为scrapbook/psr-cache的包

2)您的composer.json中没有有效的satooshi/php-coveralls版本

我建议您将包psr-cache更改为一个有效包，并修复php-coveralls版本

编写器的错误在这一点上非常明显。

如果您想要检查所有有效的软件包，请参考以下内容：
