运行phpcs时，ERROR：Referenced嗅探“PHPCompatibility”不存在即将到来

Question

我想运行phpcs工具，但是这个错误即将到来，

ERROR: Referenced sniff "PHPCompatibility" does not exist I运行了phpcs -i。那给了我，

The installed coding standards are PEAR, PSR1, Zend, Squiz, PSR12, PSR2, MySource and PHPCompatibility.

但总是会出现这个错误，错误：引用嗅探“PHPCompatibility”不存在。有什么原因？

Answer 1

根据目前的PHP Compatibility Coding Standard文档，您需要按照以下步骤操作：

1. 打开您的composer.json文件并将以下行添加到：

"require-dev": {
  "phpcompatibility/php-compatibility": "*"
  },
  "prefer-stable" : true,
  "scripts": {
  "post-install-cmd": "\"vendor/bin/phpcs\" --config-set installed_paths vendor/phpcompatibility/php-compatibility",
  "post-update-cmd" : "\"vendor/bin/phpcs\" --config-set installed_paths vendor/phpcompatibility/php-compatibility"
  }

2. 运行composer update
3. 用./vendor/bin/phpcs -p . --standard=PHPCompatibility测试
