一：介绍

由于redmine默认的额markdown和文本不是很方便使用，这里介绍一下如何
安装CKEditor富文本插件。

二：参考文档

https://redmineplugins.cn/projects/1/plugin_blocks/18?tab=installation_notes
https://github.com/a-ono/redmine_ckeditor

三：安装ImageMagick

由于CKEditor上传图片依赖ImageMagick，所以windows上必须先安装这个工具。

• windows官方下载
• ImageMagick-7.1.0-27-Q16-HDRI-x64-dll.exe

一步一步默认安装就行，然后输入：magick --version
查看一下版本号，看看是否安装完毕。

四：安装CKEditor富文本插件

1.从github上下载最新的包
2.解压到redmine/plugins并将文件夹命名为：redmine_ckeditor
3.bundle install
4.set RAILS_ENV=production
5.bundle exec rake redmine:plugins:migrate

五：配置

1.打开部署好的redmine网站
2.选择-管理-配置-一般-文本格式
3.选择Ckeditor

六：错误
