需要帮助在 Mac 上安装 rJava

Question

我正在尝试在我的 Mac 上下载 Xlconnect 软件包，但我不断收到错误消息。我能够弄清楚这是因为 mac 与 Java 有一些问题，我需要先解决这个问题。但到目前为止我还没有运气。

我尝试过的其中一件事是：https://www.chrisjmendez.com/2018/11/16/installing-xlconnect-and-rjava-on-macos/

但效果不佳。

有能成功安装rJava的大神帮忙看看吗？

configure: error: One or more Java configuration variables are not set.
Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.

If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.

您似乎还没有使用 java 变量设置环境。 尝试将此添加到您的 ~/.zshrc 或 ~/.basrc

export PATH={PATH_TO_JAVA_INSTALLATION}:$PATH
export JAVA_HOME={SAME_PATH_TO_JAVA_INSTALLATION}

您的 Java 路径最有可能在 /Library/Java/JavaVirtualMachines/{some .jdk file}
