R安装&x27；巴布亚新几内亚'；无法加载共享对象

当我运行install.packages（“png”）时，无论我是在R Studio中运行，还是作为Mac终端的超级用户运行，我都会收到以下错误。我没有成功地为这个问题实施其他解决方案。我正在使用R4.0.2（从3.6.3升级，因为它也不起作用）。我目前唯一的解决方案是使用我大学的虚拟桌面R发行版，因为它在该版本中工作。然而，它是缓慢的，只是不一样

我尝试通过自制重新安装libpng并重新初始化符号链接来解决这个问题，但我遇到了一个死胡同。

解决：找到了解决方法。在重新下载RStudio之前，必须清除RStudio并下载R。似乎已经解决了这个问题
