Mavericks Issue?

I'm not a Java expert, but I am having this issue.

Here is my version number and stuff

~/dev $ which java
/usr/bin/java
~/dev $ java -version
java version "1.6.0_65"

Seems like perhaps JAVA_HOME may not being discovered properly. I'd try manually setting that, and if that still doesn't work, mucking with binging.gyp line ~130 until you can resolve the issue.

I was having the same issue as Jamund and I've managed to work around it. The solution seems to be setting the JAVA_HOME env variable. I also updated to 1.7.0_45 but I'm not sure that had any effect on finding the solution.

I'm on Mavericks with the same version of Java and haven't seen this issue and can't reproduce it by unsetting or changing JAVA_HOME.

[xjamundx]

In case anyone else has the problem. I did the following.

1. Installed newest Java from http://java.com/en/download/mac_download.jsp
2. export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/
3. npm install java

See: http://stackoverflow.com/questions/9704376/how-to-install-java-native-development-headers-on-os-x-lion for a reference

In talking with a few other folks who have Mavericks and did not have this issue, it appears that if you had 1.7.0_45 before upgrading to Mavericks the issue doesn't appear. After Mavericks the JDK installer no longer appears to update the current_jdk link. So, the only way to solve the issue is to set JAVA_HOME or update the link to point to the latest JDK.

@kevinrc I'm having this error on macOS Sierra and idk 1.8, did you experienced it on recent models of MPB and java8?

[nselikoff]

I was experiencing a similar issue, although the file that couldn't be found was jni_md.h. Turns out, if you're using jenv (https://github.com/gcuisinier/jenv), because it uses a shim and symlink for JAVA_HOME, node-java will resolve the path to "Users" not "Library" and therefore won't include the extra darwin subdirectory (where jni_md.h is located).

[nicholasren]

I'm using jenvand run into the exactly same problem @nselikoff mentioned above.
My current workaround is copy jni_md.h and jawt_md.h from <JDK_HOME>/Contents/Home/include/darwin to <JDK_HOME>/Contents/Home/include and run npm install java

@nicholasren I am also using jenv and tried your recommended solution, but I am still getting

../src/java.h:7:10: fatal error: 'jni.h' file not found
#include <jni.h>

error. What do you suggest to do next?

[paulwcy]

I'm using jenv as well...
Setting JAVA_HOME worked for me
export JDK_HOME=$(/usr/libexec/java_home -v 1.8)

I am also facing this issue with the following specs:
