在 Windows 10 64 、PHP 7.0.22 下，运行 Yii 2.0.12，提示：The file or directory to be published does not exist: E:\wwwroot\yii2-app-advanced/vendor\bower/jquery/dist 的解决

1、打开网址：http://www.yii2-app-advanced.dev/ ，报错目录：E:\wwwroot\yii2-app-advanced/vendor\bower/jquery/dist 不存在，如图1

2、打开 E:\wwwroot\yii2-app-advanced\vendor ，确定目录 bower 不存在，如图2

3、查看 Composer 的安装提示，发现 bower 已经被替换为 bower-asset 目录了，此处为正常，如图3

4、由于刚从 PHP 5.6.27 升级到 PHP 7.0.22，决定重新安装 Composer asset plugin，无更新，如图4

5、查看 composer.json 文件，发现 “bower-asset-library”: “vendor/bower” ，如图5

6、查看 Composer 的安装提示，bower-asset 目录下的文件从缓存加载，决定清空 Composer 缓存，如图6

7、删除 E:\wwwroot\yii2-app-advanced，重新安装，如图7
composer global require “fxp/composer-asset-plugin:^1.2.0”
composer create-project yiisoft/yii2-app-advanced yii2-app-advanced 2.0.12

8、仍然提示错误，仅删除 E:\wwwroot\yii2-app-advanced\vendor，重新安装，如图8
composer install

9、重新安装 Composer asset plugin，1.3.1 版本，如图9
composer global require “fxp/composer-asset-plugin:^1.3.1”

10、运行 composer update，报错，如图10

Potential causes:
– A typo in the package name
– The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

11、目录 E:\wwwroot\yii2-app-advanced\vendor\bower 生成，只是目录为空，如图11

12、再次清空 Composer 缓存，执行命令：composer clear-cache，如图12

13、删除 E:\wwwroot\yii2-app-advanced，重新安装，如图13
composer global require “fxp/composer-asset-plugin:^1.3.1”
composer create-project –prefer-dist yiisoft/yii2-app-advanced yii2-app-advanced

14、打开网址：http://www.yii2-app-advanced.dev/ ，正常，如图14

15、总结：报错的原因有可能与Composer 缓存无关，而是在于 Composer asset plugin 的版本问题。
