Ubuntu20.24 安装ecCodes，包括 tar.gz 和 python（笔记）

动机

我的Ubuntu系统提示 grid_copy 找不到，具体问题如下：

./pre_era5.sh: line 78: grib_copy: command not found
./pre_era5.sh: line 84: codes_split_file: command not found
./pre_era5.sh: line 84: codes_split_file: command not found
./pre_era5.sh: line 84: codes_split_file: command not found
./pre_era5.sh: line 84: codes_split_file: command not found
ls: cannot access 'OUTPUTS/2d.grb_*': No such file or directory

因为 找不到 grib_copy，所以最终报错。

为此找了解决方案。废话不多说，如下：

1. 下载 ecCodes 的源文件，网址如下： https://confluence.ecmwf.int/display/ECC/Releases

2. 解压包:

# 安装环境
sudo apt install build-essential gcc gfortran cmake git subversion libnetcdff-dev libnetcdf-c++4-dev libopenmpi-dev netcdf-bin nco cdo ncl-ncarg libxml2 libxml2-utils liblapack-dev libblas-dev 
# 解压包
cd /home/user/ecmwf/
cp ~/Download/eccodes-2.32.1-Source.tar.gz
tar -zxvf eccodes-2.32.1-Source.tar.gz

3. 创建 ecCodes 的安装目录:

mkdir /home/user/ecmwf/eccodes
cd /home/user/ecmwf/eccodes

4. 通过 cmake 安装 :

cmake ../eccodes-2.32.1-Source -DCMAKE_INSTALL_PREFIX=/home/user/ecmwf/eccodes

5. 编译, 测试，安装:

make
ctest
make install

6.最后为Python 安装 eccodes

### 我的环境：python3.7 Anaconda3-2019-10
python -m pip install eccodes

或

python -m pip install --install-option="--prefix=/home/user/ecmwf/eccodes" eccodes

7. 添加环境变量作为默认

vim ~/.bashrc
# 在最末尾添加以下内容
# >>> eccodes initialize >>>
export ECCODES_DIR=/home/user/ecmwf/eccodes
export LD_LIBRARY_PATH=$ECCODES_DIR/lib
export PATH=$ECCODES_DIR/bin:$PATH

具体看官网：https://confluence.ecmwf.int/display/ECC/Releases，我只是搬运工，做笔记。
