Python 为什么我能'；在安装jupyterlab lsp扩展后是否构建jupyter lab？

这是我的第一个问题

所以，我已经使用jupyterlab一段时间了，我想得到一个很好的扩展名为jupyterlab lsp。因此，我遵循以下（有序）步骤：

在Jupyter实验室中启用扩展管理器

试图通过扩展管理器安装@krassowski/jupyterlab lsp，但它提示我需要nodejs 5+和npm

所以我去做了“pip安装nodejs”，还下载并安装了nodejs（通过这个链接：）。根据他们的说法，npm也与NodeJ一起安装

重新开放了jupyter实验室，现在我可以安装@krassowski/jupyterlab lsp。在那之后，我被要求重建jupyter实验室

我使用命令jupyter lab build，得到了以下错误日志：
