UnexpectedValueException:无法解析版本约束>=~2:无效版本字符串"~2“

Question

我试过：

1. 作曲家全球更新
2. 作曲家自助式
3. 作曲家更新

我在第三步就出错了。

我运行php7，使用Yii2构建一个网页。我在过去成功地运行了"composer更新“(正如我所记得的，也就是在将php更新到7之前)。

下面是我的composer.json

Answer 1

使用"philippfrenzel/yii2fullcalendar": "*"存在一个错误，您可以使用composer update -vvv检查此错误

你可以在这里看到：https://github.com/philippfrenzel/yii2fullcalendar/issues/76

使用此方法暂时解决以下问题：

$ composer global require fxp/composer-asset-plugin:~1.3@dev

之后，如果您在尝试执行composer时获得了另一个错误，类似于这样：

Changed current directory to /Users/xxxx/.composer

Fatal error: Call to undefined method Composer\Package\RootPackage::getConfig() in /Users/xxxx/.composer/vendor/fxp/composer-asset-plugin/Util/Config.php on line 125

若要修复此问题，只需删除文件夹：sudo rm -rf /Users/xxxx/.composer
