Question

我似乎找不到解决此错误的方法：

我已经尝试单独加载rJava，这似乎导致了这个问题，我已经从rStudio的tar.gz文件以及直接从CRAN安装，但是，它们都没有工作！

提前感谢您的帮助！

在重新下载Java x64并试用该行之后仍未解决：

Sys.setenv(JAVA_HOME="C://Program Files//Java//jre1.8.0_161")

这些是关于另一个问题的建议，我使用的是Windows 10并且出现以下错误：

Error: package or namespace load failed for 'rJava':
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: inDL(x, as.logical(local), as.logical(now), ...)
  error: unable to load shared object 'C:/Users/rawlingsD/Documents/R/win-library/3.4/rJava/libs/i386/rJava.dll':
  LoadLibrary failure:  %1 is not a valid Win32 application.

再次感谢您的帮助

问题更可能是32位与64位java安装在您的计算机上。卸载java并安装特定的位版本（64位更好）。然后安装xlsx，rJava等。

无法加载包 - 已尝试所有依赖项
