Linux | 安装 lb-toolkits
最近又需要下载葵花的数据，之前分享过一次代码。今天发现之前的环境不小心被我删了，而运行相关的代码需要安装lb-toolkits这个库，今天正好记录了一下安装lb-toolkits的过程。
这里安装的版本是1.2.4，别问为什么是这个版本，因为只安到了这个版本才成功。
- https://pypi.org/project/lb-toolkits/1.2.4/#files
本来是直接通过
pip install lb-toolkits==1.2.4
命令直接安装的，但是发现一直报错。
安装过程
下面记录一下成功安装的过程
安装python版本
这里先安装python=3.11的版本
conda create -n py311 python=3.11
安装相关依赖
由于lb-toolkits需要相关的依赖环境
库名 版本 库名 版本 库名 版本
numpy 1.2.0 pyhdf 0.10.0 h5py 1.0.0
netcdf4 1.0.0 tqdm 4.0.0 gdal 2.0.0
pillow 7.0.0 paramiko 2.10.0 cdsapi 0.5.0
所以在安装之前先安装他的依赖
conda install conda-forge::pyhdf h5py netcdf4 tqdm gdal pillow paramiko cdsapi
安装lb-toolkits 1.2.4
依赖环境安装完了，然后再使用pip 安装具体的版本
pip install lb-toolkits==1.2.4
安装成功了
测试脚本
运行相关脚本前需要再装一个库
conda install bs4
运行相关脚本，下载2023年8月和9月的数据：
#!/usr/bin/env python3
