通过Composer安装cakephp/localized时出错，与cakephp/chronos和cakephp/database冲突

Question

我尝试使用以下命令安装cakephp/localized：

composer require cakephp/localized

或者：

composer.phar require --update-with-dependencies "cakephp/localized"

并给出以下错误：

$ composer.phar require --update-with-dependencies -W "cakephp/localized"
Using version ^3.5 for cakephp/localized
./composer.json has been updated
Running composer update cakephp/localized --with-all-dependencies
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - cakephp/localized[3.5.0, ..., 3.5.2] require cakephp/cakephp ^3.5 -> satisfiable by cakephp/cakephp[3.5.0, ..., 3.10.0].
    - cakephp/cakephp[3.5.0, ..., 3.5.14] require cakephp/chronos ^1.0.0 -> found cakephp/chronos[1.0.0, ..., 1.3.0] but it conflicts with your root composer.json require (^2).
    - cakephp/cakephp[3.5.15, ..., 3.10.0] require cakephp/chronos ^1.0.1 -> found cakephp/chronos[1.0.1, ..., 1.3.0] but it conflicts with your root composer.json require (^2).
    - Root composer.json requires cakephp/localized ^3.5 -> satisfiable by cakephp/localized[3.5.0, 3.5.1, 3.5.2].


Installation failed, reverting ./composer.json and ./composer.lock to their original content.

如果我在composer.json文件中手动输入cakephp/localized no并给出composer.update命令，它会与cakephp/composer.json冲突：

$ composer update
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1

    - cakephp/localized 3.5.2 requires cakephp/cakephp ^3.5 -> satisfiable by cakephp/cakephp[3.5.0, ..., 3.10.0].
    - Only one of these can be installed: cakephp/cakephp[3.5.0, ..., 3.10.0], cakephp/database[4.0.0, ..., 4.2.7]. cakephp/cakephp replaces cakephp/database and thus cannot coexist with it.
    - Root composer.json requires cakephp/database ^4 -> satisfiable by cakephp/database[4.0.0, ..., 4.2.7].

使用选项--与所有依赖项(-W)允许升级、降级和删除当前锁定到特定版本的包。

以下依赖项位于我的composer.json文件中：

"cakephp/chronos": "^2",
"cakephp/database": "^4",
"cakephp/validation": "^4.2",

如何修复此错误？

Answer 1

我使用cakephp/localized的4.x版本解决了这个问题

Answer 2

错误消息非常清楚：

  Problem 1
    - cakephp/localized[3.5.0, ..., 3.5.2] require cakephp/cakephp ^3.5 -> satisfiable by cakephp/cakephp[3.5.0, ..., 3.10.0].
    - cakephp/cakephp[3.5.0, ..., 3.5.14] require cakephp/chronos ^1.0.0 -> found cakephp/chronos[1.0.0, ..., 1.3.0] but it conflicts with your root composer.json require (^2).

您想要安装需要cakephp/chronos v1的包，但您已经需要cakephp/chronos v2。在您自己的composer.json中将软件包降级为v1，或者搜索支持cakephp/chronos v2的其他软件包的更新版本
