Composer php friendsofsymfony/ckeditor捆绑包与sebastian/exporter冲突

成功卸下egeloen/ckeditor捆绑包后，我在安装FOS/ckeditor捆绑包时遇到问题。 （我是按照以下建议的方式做的：）

输出为：

composer require friendsofsymfony/ckeditor-bundle      
Using version ^2.1 for friendsofsymfony/ckeditor-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - friendsofsymfony/ckeditor-bundle 2.1.0 conflicts with sebastian/exporter[1.2.2].
    - friendsofsymfony/ckeditor-bundle 2.1.0 conflicts with sebastian/exporter[1.2.2].
    - friendsofsymfony/ckeditor-bundle 2.1.0 conflicts with sebastian/exporter[1.2.2].
    - Installation request for friendsofsymfony/ckeditor-bundle ^2.1 -> satisfiable by friendsofsymfony/ckeditor-bundle[2.1.0].
    - Installation request for sebastian/exporter == 1.2.2.0 -> satisfiable by sebastian/exporter[1.2.2].


Installation failed, reverting ./composer.json to its original content.

我还尝试了：

composer require friendsofsymfony/ckeditor-bundle:1.2.0

---

但我也犯了同样的错误。symfony 3.4是否有特殊版本？

您的一些其他依赖项可能需要

sebastian/exporter

<2.0，而

friendsofsymfony/ckeditor bundle

不支持该版本

您可以使用获取需要

sebastian/exporter

的软件包列表

composer why sebastian/exporter

---

然后，您可以使用它升级（因此他们需要更新的

sebastian/exporter

）或删除软件包以安装捆绑包。

我的phpunit/phpunit似乎使用了sebastian/exporter。我删除了phpunit/phpunit，现在可以安装ckeditor.phpunit 5.7是第一个支持

sebastian/exporter

2.0的版本，因此您可以尝试升级到该版本，而不是删除它。
