在R中装载任何包裹

Question

我已经在RStudio 1.2.1335版本中成功安装了tmap包。

然而，当我尝试用library(tmap)命令加载它时，我会收到以下错误消息：

Error: package or namespace load failed for ‘tmap’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/raster/libs/raster.so':
dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/raster/libs/raster.so, 6): Symbol not found: _EXTPTR_PTR
Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/raster/libs/raster.so
Expected in: /Library/Frameworks/R.framework/Resources/lib/libR.dylib
in /Library/Frameworks/R.framework/Versions/4.0/Resources/library/raster/libs/raster.so

我对所有软件包(新安装的或旧的(都有这个问题，不确定从哪里开始查找这个问题。

Answer 1

我通过重新安装R和RStudio 解决了这个问题

Answer 2

听起来您丢失了关于"光栅"的包。也许你去安装它。
