What is Solara?
Solara is an Open Source library that lets you use and build data-focused web apps (data apps) using reusable UI components. Your app will work in the Jupyter notebook and production-grade web frameworks (FastAPI, Starlette, Flask, ...).

Solara uses proven technologies and mature standards. Grow from a one-off experiment in the Jupyter notebook to a dynamic data portal in production. Built on top of Reacton to keep your code complexity under control and IPywidgets to access a rich set of UI libraries without having to write Javascript or CSS.

We care about developer experience. Solara will give your hot code reloading and type hints for faster development.

Why is Solara created?
How much time have you wasted investing in a web framework only to find out that what you need is impossible to do?

Many frameworks only solve a specific set of problems. Once you step outside of the paved path, you get stuck.

On the other extreme, you might be working with a library with no clear patterns that let you do anything. You may only be weeks away from a total code complexity nightmare, which slowly kills your project.

At the same time, starting a new framework from scratch would be unwise. We prefer to build on top of solid, battle-tested libraries, such as IPywidgets.

export const getMapTilesSettings = () => {
  if (hasExtension("mapTiles")) {
    return getExtension("mapTiles");
  }
  /* defaults */
  const api = 'https://a.tile.openstreetmap.org/{z}/{x}/{y}.png';
  return {

修改前：

修改后：

只要执行
npm i
npm i XXX@1.0 --save 等@antv/g6都会报错

解决办法：
去掉^ "@antv/g6": "3.2.1",

然后执行npm安装包相关命令，@antv/g6不会报错

• ~ 会匹配最近的小版本依赖包，比如~1.2.3会匹配所有1.2.x版本，但是不包括1.3.0
• ^ 会匹配最新的大版本依赖包，比如^1.2.3会匹配所有1.x.x的包，包括1.3.0，但是不包括2.0.0
• *这意味着安装最新版本的依赖包

二，安装最新版本

curl -sL https://deb.nodesource.com/setup_10.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh
sudo apt install nodejs

The nodejs package contains the nodejs binary as well as npm, so you don’t need to install npm separately.
In order for some npm packages to work

sudo apt install build-essential

三，删除nodejs
sudo apt remove nodejs
sudo apt purge nodejs //彻底删除　包括配置文件
sudo apt autoremove //清除依赖
