关于EPiServer.TinyMCESpellChecker / NHunspell的问题

Question

在重新安装EPiServer.TinyMCESpellChecker包时，我遇到了NHunspell依赖关系方面的问题。尝试SpellChecker会显示一条浏览器警告消息，其中包含一个错误页面的HTML，并显示它无法找到NHunspellx86.DLL。我检查了我的bin/文件夹，确实缺少了DLL。奇怪的是，它存在于NHunspell安装的nuget包/文件夹中。

以下是在重新安装NHunspell时显示的错误消息：

事实证明，出现错误消息是因为NHunspellx86和NHunspellx64 DLL位于nuget包的content文件夹中。这意味着，如果您的解决方案中存在该文件，它不会被覆盖。为了解决错误，我不得不强制卸载NHunspell (强制因为我希望nuget忽略EPiServer拼写检查依赖于它)：

uninstall-package nhunspell -Force

然后在我的网站项目的根目录中删除NHunspellx86和NHunspellx64 DLL。原来，EPiServer.TinyMCESpellChecker的最初安装已经将它们放在了那里，而它们的存在阻止nuget通过从content选项卡复制DLL来正确地重新安装软件包。删除两个DLL后，运行以下命令：

install-package nhunspell 

现在控制台应该显示NHunspell安装没有错误，当您再次运行EPiServer时，TinyMCESpellchecker应该可以正常工作！
