我尝试安装pygrib软件包。在python 2。 我安装了所有必需的软件包。 （https://jswhit.github.io/pygrib/docs/pygrib-module.html） 我命令pip安装pygrib。但它有一个错误。 我在错误脚本中找不到错误。有很多警告。但是我不认为没有安装就没问题。
如何解决此错误？

操作部分是cannot find -leccodes，这意味着它找不到库libeccodes.so
要安装它，
sudo apt install libeccodes-dev
答案 1 :(得分：0)
从2.0.2版开始，最新版本的pygrib要求使用称为ecCodes的ECMWF软件包来代替grib-api。您的gcc退出代码表示您缺少“ -leccodes”的编译标志。
ecCode可以在这里找到：https://confluence.ecmwf.int/display/ECC/ecCodes+Home 这是宣布将grib-api替换为ecCodes的地方：https://confluence.ecmwf.int/display/GRIB/Home
安装ecCodes软件包应提供gcc标志“ -leccodes”
