error when installing #122

Closed Palaeocortex closed 2 years ago

Palaeocortex commented 5 years ago

I can't install the newest release 0.6.0.post1 with Python3:

  File "./setup.py", line 22
    f'pyunicorn.{pkg}._ext.numerics',
                                   ^
SyntaxError: invalid syntax

The command is sudo python3 ./setup.py install The same error occurs with pip.

Dear Cristian,

we tested the install via setup.py and pip on different machines running Python3 on Mac OSX (Mojave), Linux and Windows and it works for us.

Please check that you actually have a Python3 environment installed and linked as the standard Python interpreter on your system.

Cheers, Jonathan

We have tracked down the bug. What you can do now is download the latest development version at: https://github.com/pik-copan/pyunicorn/archive/master.zip https://github.com/pik-copan/pyunicorn/archive/master.zip

Then install cython and then install pyunicorn via setup.py which will compile the C extensions on your machine.

Dear Jonathan, Thanks a lot for debugging! I am still getting the same error message:

  File "setup.py", line 34
    f'pyunicorn.{pkg}._ext.numerics',
                                   ^
SyntaxError: invalid syntax

Am I doing something wrong? Python3, cython and all dependencies are installed (otherwise it would complain at an earlier line). Against what is this line linking? I am not familiar with installation scripts.

ntfrgl commented 5 years ago

@jdonges This seems to be a different problem. @Palaeocortex These lines are defining the Cython extensions.

The only simple explanation for this error message that I can think of is that setup.py is in fact being executed by Python 2, and therefore the Python 3 string formatting syntax f"{}" is seen as invalid. This might be caused by any number of environment configuration issues on your machine. Please falsify by adding the following lines to the beginning of setup.py:

import sys
print(sys.version)

Dear Jonathan, I tried to install Pyunicorn in python3. but, mpl_toolkits.basemap is in python2. what should I do for installing this package? thanks for any suggestion.

jdonges commented 5 years ago

Basemap is an optional dependency. Hence, you don't need it for running most of pyunicorn's functions.

Thank you for reporting this issue, and please accept our apologies for our delay in providing a rigorous solution. This set of problems should be fully resolved with the commit linked above, which will be reflected in an upcoming new release including official wheels. I'm tentatively closing this ticket, but please let us know in case you have any trouble installing pyunicorn from the current master branch, in which case we will attempt to find a solution as quickly as possible.

Cython is now declared as a build dependency, which means that your Python package manager (e.g., pip) is responsible for automatically providing the Cython compiler without any user intervention. After the package installation process is completed, Cython is not required as a runtime dependency. The version information is now retrieved via importlib.metadata from the Python standard library.
