R-Project：xlsx 包安装失败（由于 java 问题）

我试图安装 xlsx 包，不幸的是，Java 有一个问题，我无法解决。

这是输出：

“sudo R CMD javareconf”导致：

我不知道如何解决这个java问题。我使用 RStudio 和 Fedora。 非常感谢您的帮助。

如果您安装了 Java，请尝试从命令行重置 R 的 java 配置

sudo R CMD javareconf

然后再次尝试安装rJava（您可以先重新启动RStudio）

install.packages('rJava')

如果这仍然不能解决您的问题，则错误表明 R 无法加载 getsp：

checking whether Java run-time works... 
Error: Could not find or load main class getsp

首先验证 getsp 是否可访问。

locate getsp

输出可能包含多个项目，但您应该找到如下内容：

/usr/share/R/share/java/getsp.class

然后我们希望可以访问它，因此将其导出，以便 R 可以找到它：

export CLASSPATH=/usr/share/R/share/java

在同一窗口中，启动另一个 R 会话并尝试安装rJava again.

另一件需要休息的事情是 JAVA_HOME 并重新运行javareconf

export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.71.x86_64/jre
export PATH=$PATH:$JAVA_HOME/bin
sudo R CMD javareconf

还建议unset CLASSPATH in the rJava问题 https://github.com/s-u/rJava/issues/3因为它可能会导致其他问题。如果仍然无法解决问题，您可能应该在尝试更改 JAVA_HOME 之前执行此操作并再次重置。

EDIT

鉴于这个问题在相当长一段时间内一直“未得到解答”，我想我还应该添加我的建议，即仅使用readxl https://cran.r-project.org/web/packages/readxl/index.html而是不使用 Java 的包。它安装起来更加容易，并且是 tidyverse 的一部分。只是对那些尝试使用 Excel 文件的人的一般建议。
