无法安装nloptr（R4.0.3，Ubuntu 20.04）

我试图在R4.0.3上安装nloptr，但出现以下错误：

/usr/bin/ld: /usr/local/lib/libnlopt.a(general.o): relocation R_X86_64_TPOFF32 against `nlopt_srand_called' can not be used when making a shared object; recompile with -fPIC

* removing ‘/home/giovanni/R/x86_64-pc-linux-gnu-library/4.0/nloptr’
Warning in install.packages :

有人能告诉我一个解决办法吗

提前感谢。

libnlopt dev的最新（2.6.2）包在Ubuntu 20中被破坏，出于某种原因，它被编译到一个静态库中（.so shared object missing） 几天前我遇到了类似的问题。快速修复方法是从Github下载NLOPT并自己编译

至少，它对我有用。

非常感谢！
