我正在尝试安装 CRAN 群体遗传学包hierfstat；但是 libproj.so.13 打印出以下错误：

关于如何修复此错误有什么建议吗？我正在 Ubuntu-20.04 上工作

Answer 1

我在 ubuntu 20.04 上也遇到了同样的问题。就我而言，我扩展了 LD 库路径。在bash中

export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib

在 tcsh 中

setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH\:/lib
setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH\:/usr/lib
setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH\:/usr/local/lib

之后，您已经可以看到现在可以找到共享库，如果

/usr/local/bin/proj

不会导致任何错误。
