Raspberry pi 树莓派安装 Jupyter lab

使用Jupyter lab进行python开发是非常快捷友好的方式。

其特点：

所写即所得即所见

调试方便

本文就主要介绍，怎么在树莓派上安装Jupyter lab。

---

安装jupyter lab

在终端输入以下命令：

pip3 install jupyterlab

如果网络慢可以试试使用其他源的方法，例如以下命令进行安装：

pip3 install jupyterlab -i https://pypi.tuna.tsinghua.edu.cn/simple

创建配置文件

在终端输入以下命令：

jupyter notebook --generate-config

or

jupyter-lab --generate-config

之后会输出，创建的文件详细位置，请记住这个位置。要记得，很重要。

---

设置局域网能访问Jupyter lab

使用nano修改配置文件，也就是之前生成的（配置文件路径，请使用你对应的路径做修改）

在终端输入以下命令：

nano  /home/pi/.jupyter/jupyter_notebook_config.py

找到以下配置项，去掉行首的#，并且修改为如下即可：

• c.NotebookApp.allow_origin = ‘*’ #allow all origins
• c.NotebookApp.ip = ‘0.0.0.0’ # listen on all IPs

保存退出

---

设置Jupyter lab的访问密码

在终端输入命令：

jupyter notebook password`

此时，会要求你输入密码，输入后回车即可

（注意：在输入密码的状态下，键盘按下字符是没有任何显示的，这是正常现象，继续输入最后回车即可）

例如我在这里输入密码为：makeronstie

---

重启树莓派

在命令行输入以下命令即可：

sudo reboot

---

启动jupyter lab

在命令行输入以下命令即可：

jupyter-lab

---

现在，

在本地访问 http://127.0.0.1:8888

或者

在局域网中的机器访问 http://your-ip-address:8888

即可打开,

然后输入你设置的密码，

就能在网页上操作你的树莓派和开发python程序。
