Problem installing snappy on mac m1


Thank you for reading this and appreciate all of your help.
I have a problem installing snappy on my mac m1 for a long time. I read every single comments and posts here relating installing snappy on mac or window or linux but until now no progressing.

So my setup is:
MacBook Pro (14-inch, 2021)
Apple M1 Pro Chip
Mac OS Monterey

on terminal java -version:
java version “18.0.2” 2022-07-19
Java™ SE Runtime Environment (build 18.0.2+9-61)
Java HotSpot™ 64-Bit Server VM (build 18.0.2+9-61, mixed mode, sharing)

mvn -v :
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
Maven home: /opt/apache-maven-3.8.6
Java version: 18.0.2, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-18.0.2.jdk/Contents/Home
Default locale: en_DE, platform encoding: UTF-8
OS name: “mac os x”, version: “12.5”, arch: “aarch64”, family: “mac”

nano .zshrc
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk-18.0.2.jdk/Contents/Hom$
export PATH="$JAVA_HOME/bin:$PATH"
export PATH="/opt/apache-maven-3.8.6/bin:$PATH"

I installed SNAP 9.0 and created a conda virtual environment called “py36” with Python version 3.6.

I did following steps

  1. git clone GitHub - jpy-consortium/jpy
  2. python3 bdist_wheel
  3. cd dist
  4. cp *.whl “/Users/hm/.snap/snap-python/snappy”
  5. cd /Applications/snap/bin
  6. ./snappy-conf /Users/hm/opt/miniconda3/envs/py36/bin/python3.6 /Users/hm/opt/miniconda3/envs/py36/lib/python3.6/site-packages

and i got this error

in python3:

>>> import snappy
RuntimeError: jpy: internal error: static method not found: unwrapProxy(Ljava/lang/Object;)Lorg/jpy/PyObject;

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

I would appreciate any comment and help. Thanks.


There are a few things to note.


Thank you so much for the reply.

(I use rosetta terminal)
I installed Java JDK v8 newly. I reinstalled maven too.
I installed 0.9.0 of jpy from your github link and then I could see finally “snappy install finished”

but then I faced a different error.

>>> import snappy

INFO: org.esa.s2tbx.dataio.gdal.GDALVersion: Incompatible GDAL 3.5.1 found on system. Internal GDAL 3.2.1 from distribution will be used.

And then I installed jpeg package by brew.

I renamed the file /usr/local/Cellar/jpeg/9e/lib/libjpeg.9.dylib to /usr/local/Cellar/jpeg/9e/lib/libjpeg.8.dylib

Now i can use snappy. It works without problem. Thank you so much!!!
I struggled for so long time and finally it works like a charm. Thank you thank you!


Greetings everyone!

I am also using the same Mac OS (Mac OS Monterey) and M1 Pro Chip. I have tried to install JDKv8 and maven using the rosetta terminal.

(I have tried both JDKv8 - zulu-8.jdk and adoptopenjdk-8.jdk)
(Apache Maven 3.8.6 84538c9988a25aec085021c365c560670ad80f63
Maven home: /opt/apache-maven-3.8.6
Java version: 1.8.0_292, vendor: AdoptOpenJDK, runtime: /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/jre
Default locale: en_DE, platform encoding: UTF-8
OS name: “mac os x”, version: “10.16”, arch: “x86_64”, family: “mac”)
python 3.7

Using 0.9.0 of jpy, i have built the .whl and followed these steps:

  1. git clone GitHub - jpy-consortium/jpy
  2. python3 bdist_wheel
  3. cd dist
  4. cp *.whl “/Users/hm/.snap/snap-python/snappy”
  5. cd /Applications/snap/bin
  6. ./snappy-conf /Users/hm/opt/miniconda3/envs/py36/bin/python3.6 /Users/hm/opt/miniconda3/envs/py36/lib/python3.6/site-packages

There are no errors while building the jpy wheel but however, i have this error after executing step6

INFO: Installing from Java module ‘/Applications/snap/snap/modules/org-esa-snap-snap-python.jar’
INFO: Installing jpy…
ERROR: The module ‘jpy’ is required to run snappy, but no binary ‘jpy’ wheel matching the pattern
‘jpy-{version}-cp36-{abi_tag}-macosx_10_9_x86_64.whl’ could be found.
You can try to build a ‘jpy’ wheel yourself, then copy it into
“/Users/pavanmugudasanjeevamurthy/.snap/snap-python/snappy”, and then run the configuration again.
Unzip the jpy sources in /Users/pavanmugudasanjeevamurthy/.snap/snap-python/snappy/, then
cd jpy-<version> python bdist_wheel
cp dist/*.whl "/Users/pavanmugudasanjeevamurthy/.snap/snap-python/snappy" Or get the source code from and follow the build instructions: git clone GitHub - bcdev/jpy: A bi-directional Python-Java bridge used to embed Java in CPython or the other way round.
$ cd jpy
ERROR: Configuration failed with exit code 10

and when importing snappy ModuleNotFoundError

Can anybody please help me, @YumYumYumi you have succeeded in installing the snappy (on M1) can you please help me out with where I am going wrong?

Thanks in advance
