Question

我正在尝试使用Java配置R，在运行sudo R CMD javareconf    12:16:29  23.11.17 Java interpreter : /usr/bin/java Java version : 9.0.1 Java home path : /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home Java compiler : /usr/bin/javac Java headers gen.: /usr/bin/javah Java archive tool: /usr/bin/jar System Java on macOS trying to compile and link a JNI program detected JNI cpp flags : -I/System/Library/Frameworks/JavaVM.framework/Headers detected JNI linker flags : -framework JavaVM clang -I/usr/local/Cellar/r/3.4.2/lib/R/include -DNDEBUG -I/System/Library/Frameworks/JavaVM.framework/Headers -I/usr/local/opt/gettext/include -I/usr/local/opt/readline/include -I/usr/local/include -fPIC -g -O2 -c conftest.c -o conftest.o conftest.c:1:10: fatal error: 'jni.h' file not found #include <jni.h> ^~~~~~~ 1 error generated. make: *** [conftest.o] Error 1 Unable to compile a JNI program JAVA_HOME : /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home Java library path: JNI cpp flags : JNI linker flags : Updating Java configuration in /usr/local/Cellar/r/3.4.2/lib/R Done.后，我得到了这个。

fatal error: 'jni.h' file not found

我对{{1}}感到担忧。

结果我可以安装rJava。

有什么想法吗？谢谢！

好的！

似乎我修复了用java重新安装R的问题

brew reinstall R --with-openblas --with-java然后我运行sudo R CMD javareconf \ JAVA_CPPFLAGS='-I/System/Library/Frameworks/JavaVM.framework/Headers -I/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/

使用以下输出：

/usr/local/Cellar/r/3.4.2/lib/R/bin/javareconf: line 66: -I/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/: No such file or directory

我将JAVA_HOME设置为：

export JAVA_HOME="$(/usr/libexec/java_home)"

这是对的吗？或者最好不要定义JAVA_HOME？
