问题描述
当我尝试运行 jupyter lab build 时出现错误。我尝试卸载 jupyterlab 并重新安装它，我还对整个 anaconda 尝试了这种方法。我在 Windows 10 上运行它。这是错误：
[LabBuildApp] JupyterLab 3.0.4
[LabBuildApp] Building in c:\users\acrul\anaconda3\share\jupyter\lab
[LabBuildApp] Building jupyterlab assets (production,minimized)
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.
An error occured.

解决方法
不知道我是怎么解决的，但我反复以管理员身份运行这些
jupyter lab clean
jupyter lab clean --all
pip uninstall jupyterlab
pip install jupyterlab
然后还从另一个文件夹中启动了 jupyter lab 服务器。
