python - 由于构建错误，无法在 JupyterLab 中添加扩展
问题描述
每当我在 JupyterLab 中添加扩展时，它都会要求我更改构建，但每次运行命令时jupyter lab build都会出现以下错误：RuntimeError: JupyterLab failed to build. 我尝试了人们提出相同问题的各种解决方案，但没有一个奏效。这是我运行此命令时的日志文件：

有一百万个错误，但我不确定是什么原因造成的。任何帮助，将不胜感激。
解决方案
这很可能是由于您在 jupyterlab 中安装的另一个扩展（对我来说是jupyterlab-latex）。
基于您的错误路径的快速谷歌搜索表明，在您的情况下它可能是jupyter-lsp（注意：它对 jupyterlab 版本有上限<2.1.0a0）。尝试
jupyter labextension uninstall @krassowski/jupyterlab-lsp
pip uninstall jupyter-lsp
jupyter lab build
