我尝试将新软件包安装到项目中，但出现此错误：
问题1 -symfony / var-dumper [v3.4.22]可以满足所请求的软件包symfony / var-dumper（锁定在v3.4.22，要求为^4.3@dev），但它们与您的要求或最低稳定性相冲突。 问题2 -symfony / symfony的安装请求未设置版本（解析为1.0.0）-> symfony / symfony可以满足[未设置版本（解析为1.0.0）]。 -cmen / google-charts-bundle dev-master需要symfony / framework-bundle ^ 2.7 || ^ 3.0 || ^ 4.0-> symfony / framework-bundle [v3.4.22，2.7.x-dev，2.8.x-dev，3.0.x-dev，3.1.x-dev，3.2.x-dev，3.3.x-开发人员，3.4.x开发人员，4.0.x开发人员，4.1.x开发人员，4.2.x开发人员，4.3.x开发人员
.....
不要安装symfony / framework-bundle 2.7.x-dev |删除 symfony / symfony未设置版本（解析为1.0.0）
然后我尝试更新，但收到相同的错误消息。我对作曲家所做的任何事情都会给我同样的错误。
这是我的composer.json文件：

我可能在某个时候打破了它，但是我绝对不知道如何解决这个问题。你有什么线索吗？
=>编辑：它必须来自json文件。我删除了供应商文件夹和composer.lock，安装了新版本的composer，并且遇到了同样的问题。也许我搬了一些我不知道的东西
=> Edit2：取消所有“替换”行，现在我有了：
使用版本^1.5@dev作为树枝/扩展名./composer.json已经 使用软件包信息更新了Loading Composer存储库 更新依赖关系（包括require-dev）您的需求可以 不能解析为一组可安装的软件包。
问题1 -结论：请勿安装doctrine / event-manager 1.0.x-dev -结论：请勿安装doctrine / event-manager 1.0.x-dev -原则/事件管理器v1.0.0与原则/公共[v2.7.3]冲突。 -原则/事件管理器v1.0.0与原则/公共[v2.7.3]冲突。 -教义/事件管理器〜1.0的安装请求->教义/事件管理器[1.0.x-dev，v1.0.0]可满足。 -教义/通用的安装要求（安装在v2.7.3）->教义/通用的安装要求[v2.7.3]。
安装失败，将./composer.json恢复为原始状态 内容。
