EPiServer.TinyMCESpellChecker / NHunspell的问题

Question

在重新安装EPiServer.TinyMCESpellChecker软件包的过程中，我遇到了NHunspell依赖性问题。 试用SpellChecker会在浏览器警报消息上显示错误页面的HTML，并显示无法找到NHunspellx86.DLL的消息。 我检查了bin /文件夹，确实缺少DLL。 奇怪的是，它存在于NHunspell安装的nuget包/文件夹中。

这是我特别安装NHunspell时显示的错误消息：

Answer 1

事实证明，由于NHunspellx86和NHunspellx64 DLL位于nuget包的内容文件夹中，因此出现了错误消息。 这意味着，如果解决方案中存在该文件，则该文件不会被覆盖。 为了解决该错误，我不得不强制卸载NHunspell（强制执行是因为我希望nuget忽略EPiServer拼写检查器所依赖的）：

uninstall-package nhunspell -Force

然后删除我网站项目根目录中的NHunspellx86和NHunspellx64 DLL 。 事实证明，EPiServer.TinyMCESpellChecker的原始安装已将它们放到那里，并且它们存在的事实阻止了nuget通过从内容选项卡复制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，控制台应显示NHunspell的安装没有错误，并且当再次运行EPiServer时，TinyMCESpellchecker可以正常运行！
