我只想了解下面发生的事情。我正在使用MacO，最近从bash切换到zsh。然后我安装了jupyterlab-lsp。你能开导我吗？

Answer 1

问题是因为jupyter服务器无法找到语言服务器。在我的案例中，jupyter是使用/ opt / miniconda3 /下的conda环境（miniconda）安装和维护的，而我的nodejs位于/ usr / local /下。理想情况下，如果您已经在使用conda管理器，则将要完全卸载nodejs并使用conda重新安装它。否则，请删除整个anaconda / conda，然后根据安装nodejs的方式/位置，使用pip或brew重新安装python（https://www.python.org/downloads/release/python-381/）和jupyter。

我可以按照以下步骤解决问题：

1。）完全卸载节点js。我可以通过运行nvm uninstall <version>来做到这一点，或者如果您正在使用自制软件，请先运行brew uninstall node然后在终端上运行rm -f /usr/local/bin/npm。此外，您可以遵循以下参考：How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

2。）重新安装nodejs。 conda install -c conda-forge nodejs

3。）安装语言服务器。请参见参考：https://github.com/krassowski/jupyterlab-lsp/blob/master/LANGUAGESERVERS.md#installing-language-servers

4。）重新启动终端并运行jupyter lab。

现在，这是我能够解决我的问题的最佳答案。
