New submission from xz_sophos <xing.zh...@sophos.com>:
When trying to build python 3.9.1 on Mac OSX 10.15, one of the building step by
make is to run this command:
DYLD_FRAMEWORK_PATH=/Users/jenkins/BaseFolder/savmac-python ./python.exe -E -S
-m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
echo "generate-posix-vars failed" ; \
rm -f ./pybuilddir.txt ; \
exit 1 ; \
fi
It would produce this error message:
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Python path configuration:
PYTHONHOME = (not set)
PYTHONPATH = (not set)
program name = '/Library/Frameworks/Python.framework/Versions/3.7/bin/python3'
isolated = 0
environment = 0
user site = 1
import site = 0
sys._base_executable =
'/Library/Frameworks/Python.framework/Versions/3.7/bin/python3'
sys.base_prefix =
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9'
sys.base_exec_prefix =
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9'
sys.platlibdir = 'lib'
sys.executable =
'/Library/Frameworks/Python.framework/Versions/3.7/bin/python3'
sys.prefix =
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9'
sys.exec_prefix =
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9'
sys.path = [
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9/lib/python39.zip',
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9/lib/python3.9',
'/Users/jenkins/BaseFolder/savmac-python/sophos/tmp/Python.framework/Versions/3.9/lib/lib-dynload',
]
Fatal Python error: init_fs_encoding: failed to get the Python codec of the
filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'
Current thread 0x000000011668ddc0 (most recent call first):
<no Python frame>
15:08:54 stdout: generate-posix-vars failed
make: *** [pybuilddir.txt] Error 1
Please note that current working directory is :
/Users/jenkins/BaseFolder/savmac-python
In the Mac, there is already a python 3.7 installed at:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3
I wonder what's the root cause of the above ./python.exe error, as I don't have
this error on a different MacOS 10.15 with an existing installation of "python
launcher.app" (version 3.9.1)
