.onLoad 在“rJava”的 loadNamespace() 中失败

Question

我是运行 Win 10 64-bi，Java 版本 1.8.0.221。加载 xlsx 包时，我在版本 3.5.2 的 R Studio 中遇到错误 - 也是 64 位。错误在于加载 rJava。关于如何解决这个问题的任何想法？我被困住了，无法前进。谢谢

我添加了以下内容，然后正确加载了 rJava。

Sys.setenv(JAVA_HOME='C:\Program Files\Java\jre1.8.0_221')

.onLoad 在“rJava”的 loadNamespace() 中失败
