在 jupyterlab 中不渲染/显示情节图。因此，我尝试安装扩展 jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyterlab-plotly。之后，我被要求运行 jupyter 实验室构建，但失败了。我不知道问题出在哪里。我尝试过网络，但我很想寻求建议。
安装信息： 我用 pyenv 安装了一个 venv，运行 python 3.8.5。
jupyter --version jupyter 核心：4.7.1 jupyter 笔记本：6.4.0 qtconsole : 未安装 ipython：7.25.0 ipykernel：6.0.3 jupyter 客户端：6.1.12 jupyter 实验室：3.0.12 nbconvert：6.1.0 ipywidgets：7.6.3 nb 格式：5.1.3 特质：5.0.5
npm --version 7.11.2
节点 --version v16.1.0
由于公司要求，我被限制使用 WSL1。
我将在命令输出下方发布
任何建议将不胜感激。我不知道如何解决这个问题。 谢谢

Build failed.
Troubleshooting: If the build failed due to an out-of-memory error, you
may be able to fix it by disabling the dev_build and/or minimize options.
If you are building via the jupyter lab build command, you can disable
these options like so:
jupyter lab build --dev-build=False --minimize=False
You can also disable these options for all JupyterLab builds by adding these
lines to a Jupyter config file named jupyter_config.py:
c.LabBuildApp.minimize = False
c.LabBuildApp.dev_build = False
If you don’t already have a jupyter_config.py file, you can create one by
adding a blank file of that name to any of the Jupyter config directories.
The config directories can be listed by running:
jupyter --paths
Explanation:
dev-build: This option controls whether a dev or a more streamlined
production build is used. This option will default to False (i.e., the
production build) for most users. However, if you have any labextensions
installed from local files, this option will instead default to True.
Explicitly setting dev-build to False will ensure that the production
build is used in all circumstances.
minimize: This option controls whether your JS bundle is minified
during the Webpack build, which helps to improve JupyterLab’s overall
performance. However, the minifier plugin used by Webpack is very memory
intensive, so turning it off may help the build finish successfully in
low-memory environments.

答案 0 :(得分：1)
您不需要从源代码安装扩展。 JupyterLab 3.0 引入了预构建的扩展系统，该系统允许用户从 pip（和 conda）安装扩展，而无需构建步骤，从而消除了对失败构建进行故障排除的所有麻烦。您似乎使用了一套旧的安装说明来安装 plotly，因为 plotly 5.0+ 支持 JupyterLab 的预构建扩展。首先卸载你刚刚安装的源扩展（不需要）：
jupyter labextension uninstall @jupyter-widgets/jupyterlab-manager jupyterlab-plotly plotlywidget
可选：验证扩展列表：
jupyter labextension list
然后使用 pip 或 conda 安装一个新的 plotly 版本：
pip install "plotly>=5" "ipywidgets>=7.6"
# or, if using conda:
# conda install -c conda "plotly>=5"
# conda install "ipywidgets>=7.6"
同时包含小部件和渲染器，因此无需单独安装 plotlywidget。
再次检查扩展列表：
jupyter labextension list
您现在应该看到带有以下内容的行：
jupyterlab-plotly v5.1.0 enabled OK
@jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK (python, jupyterlab_widgets)
（当然以后版本可能会更新）。
