JupyterLab 3.0.4构建错误。[webpack-cli] [31mTypeError：' Compilation‘参数必须是编译的实例

Question

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，我也尝试了整个anaconda的方法。我在Windows 10上运行它。错误如下：

[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.

和日志文件。我假设错误在这里: webpack-cli31mTypeError：‘(c:\users\acrul\anaconda3\share\jupyter\lab\staging\node_modules\webpack\lib\javascript\JavascriptModulesPlugin.js:119:10)’参数必须是Function.getCompilationHooks编译的实例

Answer 1

不确定我是如何解决这个问题的，但我反复以admin身份运行这些程序

jupyter lab clean
jupyter lab clean --all
pip uninstall jupyterlab
pip install jupyterlab

然后还从另一个文件夹启动了jupyter lab服务器。
