  Could not open the editor: No editor descriptor 
  for id org.eclipse.jdt.ui.CompilationUnitEditor

And inside "Details" of the error, I have the following description:

What can I do to solve this problem? I don't do anything, I just update Eclipse from their own "Check for Updates".

我能做些什么来解决这个问题？我什么都不做，我只是从他们自己的“检查更新”中更新 Eclipse。

As you can see here, a workaround for your problem is just move the "~/.eclipse" to another folder.

正如您在此处看到的，解决您的问题的方法是将“~/.eclipse”移动到另一个文件夹。

So:

所以：

1. Close Eclipse
2. Open "Terminal"
3. Type the following command:

1. 关闭日食
2. 打开“终端”
3. 输入以下命令：

e.g.:

例如：

mv ~/.eclipse somewhereYouWant

When I got this problem, I just:

当我遇到这个问题时，我只是：

mv ~/.eclipse home/paladini/Downloads

Had a similar error when I removed Eclipse Typescript plugin

当我删除Eclipse Typescript 插件时出现了类似的错误

Tried to open typescript(*.ts) files and got this error:

尝试打开 typescript(*.ts) 文件并收到此错误：

No editor descriptor for id com.palantir.typescript.text.typeScriptEditor

And I was not allowed to move the workspace.

而且我不被允许移动工作区。

On Eclipse Oxygen, Window -> Perspective -> Close All worked for me.

在 Eclipse Oxygen 上，Window -> Perspective -> Close All 对我有用。

The other solutions here didn't work for me.

这里的其他解决方案对我不起作用。

Perhaps my problem was as the result of trying to get eclipse setup the first time and re-installed different versions of it: a c++ version and then a plain base version + separately installed add-ons. (Since I also want to use it for other languages I was confused how to set it up.)

也许我的问题是第一次尝试安装 eclipse 并重新安装它的不同版本的结果：一个 c++ 版本，然后是一个普通的基础版本 + 单独安装的附加组件。（因为我也想将它用于其他语言，所以我很困惑如何设置它。）

Solution:I closed eclipse, then renamed: ~/eclipse, ~/workbenchand ~/.eclipse; (in other words, remove them), and finally reinstalled, and restarted.

解决方案：我关闭了eclipse，然后重命名了：~/eclipse, ~/workbenchand ~/.eclipse; （换句话说，删除它们），最后重新安装，并重新启动。

cd ~
mv .eclipse           .eclipse~            #renames
mv  eclipse            eclipse~ 
mv  eclipse-workspace  eclipse-workspace~

~/nobak/Installers/eclipse/eclipse-installer/eclipse-inst    #reinstall

eclipse/cpp-2018-09/eclipse/eclipse   #restart
