【问题描述】:
我想安装需要安装proj4 包的ggalt 包,但是当我安装proj4 时会抛出错误libproj and/or proj_api.h not found in standard search locations。
我的电脑是Mac,我用brew install proj安装了PROJ.4,R的版本是3.6.0_2。我在互联网上搜索了这个问题,但没有找到解决它的方法。我不是编码员,刚开始学习R,所以现在不知道该怎么做。
报错如下:

【问题讨论】:
-
proj是否包含所需的proj_api.h?它位于哪里?brew ls --verbose proj应该有助于回答这些问题。 -
proj_api.h位于/usr/local/Cellar/proj/6.1.0/include/proj_api.h -
能否在安装
proj4包之前将环境变量PKG_CPPFLAGS定义为-I/usr/local/Cellar/proj/6.1.0/include/? -
我使用
export PKG_CPPFLAGS="-I/usr/local/Cellar/proj/6.1.0/include"和Sys.setenv("PKG_CPPFLAGS"="-I/usr/local/Cellar/proj/6.1.0/include"),但不起作用 -
错误信息保持不变?顺便说一句,你为什么不使用 CRAN 提供的二进制包。我试图重现该问题,并且安装包没有问题。
