我尝试通过RDRPOSTagger安装devtools软件包。

devtools::install_github("bnosac/RDRPOSTagger", build_vignettes = TRUE)

我的CPU上的Java版本：java 10.0.2 64位

我尝试使用qdap程序包，该程序包也需要rJava，而且效果很好。

错误：软件包“ rJava”无法加载

由于未设置JAVA_HOME，因此未加载此软件包。

这可以通过首先安装来完成，具体取决于您的R（32位或64位），Java 32位还是64位。

从此处下载Java：https://www.java.com/en/download/

使用此查找JAVA_HOME地址：

find.java <- function() {
        for (root in c("HLM", "HCU")) for (key in c("Software\\JavaSoft\\Java Runtime Environment", 
            "Software\\JavaSoft\\Java Development Kit")) {
            hive <- try(utils::readRegistry(key, root, 2), 
              silent = TRUE)
            if (!inherits(hive, "try-error")) 
              return(hive)
        }
        hive
    }

加载find.java，您将找到JAVA_HOME的地址。在此输入该地址：

Sys.setenv(JAVA_HOME='C:\\Your\\Java\\Directory')
library(rJava)

那应该加载软件包rJava。

错误：“ i386”的加载失败

此错误可能是因为您同时下载了R（32位和64位）两个版本，而devtools尝试为这两个版本进行构建。

您可以使用此：

devtools::install_github("mne-tools/mne-r", INSTALL_opts=c("--no-multiarch"))

我也遇到了类似类型的错误，在搜索后发现了适用于我的解决方案。
