Hi, I got the following erorr when I use pypy3 from homebrew. How to solve the problem? Should I use pypy3 independent of homebrew? If so, could anybody let me know how to do so? The download link only show Python 3.6, does it work for other versions of Python? Thanks. https://www.pypy.org/download.html $ pypy3 -mpip install -U JPype1 Collecting JPype1 Using cached JPype1-0.7.5.tar.gz (645 kB) Installing collected packages: JPype1 Running setup.py install for JPype1 ... error ERROR: Command errored out with exit status 1: command: /usr/local/bin/pypy3 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/private/tmp/mktemp/pip-install-6pnf_iup/JPype1/setup.py'"'"'; __file__='"'"'/private/tmp/mktemp/pip-install-6pnf_iup/JPype1/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /private/tmp/mktemp/pip-record-594dwb7h/install-record.txt --single-version-externally-managed --compile --install-headers /usr/local/Cellar/pypy3/7.3.1_1/libexec/include/JPype1 cwd: /private/tmp/mktemp/pip-install-6pnf_iup/JPype1/ Complete output (61 lines): running install running build running build_py creating build creating build/lib.macosx-10.7-x86_64-3.6 creating build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jcollection.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_classpath.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jio.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_pykeywords.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jproxy.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_gui.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jmethod.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/nio.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jstring.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/__init__.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/types.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/beans.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jvmfinder.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/imports.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jcustomizer.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_core.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jinit.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jarray.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jobject.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/pickle.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jclass.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jexception.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/reflect.py -> build/lib.macosx-10.7-x86_64-3.6/jpype copying jpype/_jpackage.py -> build/lib.macosx-10.7-x86_64-3.6/jpype running build_ext running build_java Using Jar cache creating build/lib creating build/lib/org creating build/lib/org/jpype creating build/lib/org/jpype/classloader copying native/jars/org/jpype/classloader/JPypeClassLoader.class -> build/lib/org/jpype/classloader copying native/jars/org.jpype.jar -> build/lib running build_thunk Building thunks including thunk build/lib/org/jpype/classloader/JPypeClassLoader.class including thunk build/lib/org.jpype.jar Call build extensions Call build ext building '_jpype' extension creating build/temp.macosx-10.7-x86_64-3.6 creating build/temp.macosx-10.7-x86_64-3.6/build creating build/temp.macosx-10.7-x86_64-3.6/build/src creating build/temp.macosx-10.7-x86_64-3.6/native creating build/temp.macosx-10.7-x86_64-3.6/native/python creating build/temp.macosx-10.7-x86_64-3.6/native/common gcc -pthread -arch x86_64 -DNDEBUG -O2 -fPIC -DMACOSX=1 -Inative/common/include -Inative/python/include -Ibuild/src -Inative/jni_include -I/usr/local/Cellar/pypy3/7.3.1_1/libexec/include -c build/src/jp_thunk.cpp -o build/temp.macosx-10.7-x86_64-3.6/build/src/jp_thunk.o -g0 -std=c++11 -ggdb warning: include path for stdlibc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead [-Wstdlibcxx-not-found] In file included from build/src/jp_thunk.cpp:1: In file included from build/src/jp_thunk.h:3: native/common/include/jpype.h:64:10: fatal error: 'map' file not found #include <map> ^~~~~ 1 warning and 1 error generated. error: command 'gcc' failed with exit status 1 ---------------------------------------- ERROR: Command errored out with exit status 1: /usr/local/bin/pypy3 -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/private/tmp/mktemp/pip-install-6pnf_iup/JPype1/setup.py'"'"'; __file__='"'"'/private/tmp/mktemp/pip-install-6pnf_iup/JPype1/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' install --record /private/tmp/mktemp/pip-record-594dwb7h/install-record.txt --single-version-externally-managed --compile --install-headers /usr/local/Cellar/pypy3/7.3.1_1/libexec/include/JPype1 Check the logs for full command output. -- Regards, Peng
