Call pip3 from python folder build by me call pip3 from the /usr/bin - Suryavarman - Oct-01-2019
I have build the latest release of python3 on a Mageia7 system.
Here the configuration command line:
./configure --prefix=${PY_PATH} --enable-sharedAnd if I call pip3 like that:
${PY_PATH}/bin/pip3 …${PY_PATH}/bin/python3 pip3 …${PY_PATH}/bin/python3 ${VENV_PATH}/bin/pip3 …${PY_PATH}/bin/python3.7 ${VENV_PATH}/bin/pip3.7 …${PY_PATH}/bin/python3.7m ${VENV_PATH}/bin/pip3.7 …All this command lines have the same result.
An output example:
Output:Requirement already satisfied, skipping upgrade: apipkg>=1.4 in /usr/local/lib/python3.7/site-packages (from execnet>=1.1->pytest-xdist) (1.5)Error:ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission non accordée: '/usr/local/bin/f2py'
Consider using the `--user` option or check the permissions.${PY_PATH}/bin/python3 ${VENV_PATH}/bin/pip3 call the pip3 system from /usr/bin?(Please don't ask me to use a venv, virtualenv or anaconda or wathever... I hate the hasardous behaviour of this things.
)Response: don't build python with the shared option.
It's works. I don't khow why.

The problem is not from where pip starts, you do not have write permission for /usr/local/lib/python3.7/site-packages as a user.
So you have to use sudo or 'pip install --user packagename'

Hi,
I haven't build and install python in the files system but in a /home/username/Python folder.
The building otpion
--enable-shared cause this error. Without this option it's work.

If you need to activate the --enable-shared the answer is:
./configure --prefix=${PY_PATH} --enable-shared LDFLAGS=-Wl,-rpath=${PY_PATH}/lib --enable-optimizations # --enable-optimizations is optional
make -j 16
make altinstallIf you have this error:./python: symbol lookup error: ./python: undefined symbol: __gcov_indirect_callDelete ${PY_PATH} folder befor to call configure.

To use waf i need do define some symbolic link:
ln -sf ${PY_PATH}/bin/python3.7m ${PY_PATH}/bin/python3
ln -sf ${PY_PATH}/bin/pip3.7 ${PY_PATH}/bin/pip3
ln -sf ${PY_PATH}/bin/pip3.7 ${PY_PATH}/bin/pip
ln -sf ${PY_PATH}/bin/python3.7m-config ${PY_PATH}/python3.7-config
ln -sf ${PY_PATH}/bin/python3.7m-config ${PY_PATH}/bin/python3-config
