Question

我是erlang的新手。我安装了erlide plugi，当我尝试打开Erlang首选项（Window - ＆gt; Preferences - ＆gt; Erlang）时出现以下错误，＆＃34;创建此首选项页面时出错。＆＃34;。我已经附加了错误的日志。这是我创建的新工作区。它曾经与eclipse Luna合作。我试图在Eclipse Mars中使用它，我收到了这个错误。所以，我试着检查以前版本的eclipse，我仍然得到同样的错误。不确定出了什么问题。

我也试过卸载我的erlang（erl5.9.1）有人可以帮助我，我在这里缺少什么吗？

谢谢，维杰

Answer 1

它是什么版本的erlide？你能试试最新的0.33.1吗？我相信这个问题与那里修复的问题相同（＃290 @ github）。

另外，请使用https://github.com/erlang/erlide_eclipse/issues报告

最好的问候，维拉德

Answer 2

我安装了最新版本0.33.1但是，遇到了同样的问题。有人提到类似问题的“检查更新”选项。因此，我尝试检查Erlide插件的更新，从而降低了插件版本。我尝试了几次，每次都降低了版本。最后，我能够与verion 0.31.0达成和解，就像插件兼容性问题一样。
