如何解决 jupyterlab-vim 的安装错误

Question

我正在尝试安装 jupyterlab-vim，它是 jupyter-lab 的 vim 扩展。从这个简短的错误消息中，有人知道该怎么做吗？

我已尝试更新 npm @phosphor/domutils 包。 npm info @phosphor/domutils 显示我有版本 1.1.3，这似乎是必要的依赖项，查看 package.json。还是没有运气。

jupyter-lab 版本为 1.1.0a1。

安装脚本是

jupyter labextension install jupyterlab_vim

An error occured.
KeyError: '@phosphor/domutils'
See the log file for details:  /var/folders/lr/y3b61w391ldgpfc53_x3y9x00000gp/T/jupyterlab-debug-2l4e0j6s.log

日志文件的内容如下。
