r - 运行 rize - R 时包“rJava”的配置失败

问题描述

我正在尝试使用该rize软件包为 ShinyApp 创建一个 Dockerfile。从rize::shiny_dockerize()App 目录启动命令。所需的软件包之一是xlsx（可能它也在尝试安装 rJava）。我收到以下错误：

有谁我可以把它放在rize包里工作吗？

解决方案

看起来您在设置 Java 的正确位置时遇到了问题。请注意，让自己R开心Java可能会有点困难。

看看这里：http ://www.owsiak.org/r-java-11-and-making-sure-you-can-load-rjava/示例。它是macOS基于的，但仍然应该可以正常工作。

基本上，您想要做的是设置您在安装JAVA_HOME时指向的这种方式。Java完成后，您可以R cmd javareconf像这样运行

> sudo R CMD javareconf \
JAVA_HOME=${JAVA_HOME} \
JAVA=${JAVA_HOME}/bin/java \
JAVAC=${JAVA_HOME}/bin/javac \
JAVAH=${JAVA_HOME}/bin/javah \
JAR=${JAVA_HOME}/bin/jar

确保您已经gcc安装并且可以编译简单的C代码。
