When using jupyterlab to try to install a new labextension, the installation nodejs version error occurred. Many extension modules have been unable to be installed or failed to install. The author has found various solutions, as follows:

• Method 1: Deploy Anaconda and JupyterLab on the server

• Method 2: Delete the package and then install it

• Method 3: Jupytelab How to install labextension

• Method 4: Through npm Install nodejs

• Method 5: The civet cat changes to the prince - as shown below:

The result... doesn’t work. Of course, you can also try the above methods, maybe which one will work for you.

Cause analysis

Later I found out: labextension requires nodejs version 10.0 or above to install the extension plug-in! !!
The author found by querying various nodejs versions in his own environment that most versions

1. nodejs --version   # v14.4.1 这个是通过方法四安装的
2. pip list                  # v0.1.1 这个是通过pip安装的
3. conda list             # v4.6.5 这个是通过conda安转的

Although nodejs installed through npm exceeds v10.0, in the jupyterlab environment It cannot be used (if you find something that can be used, please communicate with me). I found that there were too many installed versions, so I simply uninstalled the nodejs installed by pip conda, and then found a way to install a nodejs version exceeding v10.0.

Solution

Specify the installation version, you can install it through the following command:

Method 1 You can first try to search Check the nodejs version:

conda search nodejs # 搜索conda下的nodejs版本。
conda install nodejs=14.7.0 -c conda-forge

Method 2. conda search nodejs -c conda-forge #Search for the nodejs version under conda-forge.

Or directly enter conda-forge under anaconda official website Search the repo you want

conda install -c conda-forge/label/cf202003 nodejs

Select one of the above methods
