JypyterLab学习之二(JypyterLab编译运行)

一、git clone代码

git clone XXX

创建环境

conda创建python环境

conda create -n jupyterlab python=3.8
conda activate jupyterlab

conda创建node环境

conda search nodejs # 搜索conda下的nodejs版本。
conda install nodejs=16.13.1 -c conda-forge

二、安装python依赖

官网给的命令是：

pip install -e .

这个命令会报各种错，可以换成下面这个：

pip install -v -e .

如果执行报错，先执行

jupyter lab clean
jupyter lab build --minimize=False --dev-build=False

如果报下面错误,需要手动执行：

npm install -g node-gyp

需要安装hatch打包工具，可执行下面命令进行安装：

conda install -c conda-forge hatch

六、开发者模式启动jupyter lab

jupyter lab --dev-mode
jupyter lab --dev-mode --watch
jupyter lab --dev-mode --watch --extensions-in-dev-mode

启动如果报下面错误：

上面是因为ipykernel有问题，需要先查看ipykernel的位置：

jupyter kernelspec list

>Available kernels:python3    C:\Users\mbshq\AppData\Roaming\jupyter\kernels\python3

打开C:\Users\mbshq\AppData\Roaming\jupyter\runtime，删除runtime文件夹下的内容，重新启动即可。

七、独立运行example

将目录切换到examples/下执行：

jlpm
run build:examples

将目录切换到具体的example目录下执行：

python main.py
