Install successfully on version 6.7.0

@xcTorres I think this happened because I failed to configure editdistpy properly for systems that cannot install via prebuilt wheels, sorry about that. I have made some changes to the package configuration, could you please try the following command

pip install -U symspellpy==6.7.3 --no-cache-dir

and let me know the results? Thank you!

[xcTorres]

Sorry, still cannot work. But when I use the following command it works.

CFLAGS='-stdlib=libc++' pip install -U symspellpy==6.7.3 --no-cache-dir

Looks like an extra compiler flag is required on some macOS version. If you don't mind, could you try and install just editdistpy==v0.1.3rc1 to see if it can install without the extra flags (I added the extra flag for macOS into its setup script)?

pip install -U editdistpy==0.1.3rc1 --no-cache-dir

And may I know which macOS version are you running? So that other users who encounter similar problem can find your solution. Thanks!

My Mac version: 10.15.7

I am not able to install editdispy using "pip install -U editdistpy==0.1.3rc1 --no-cache-dir", here is the error.

I made some more changes to the build, could you please try this

pip install -U editdistpy==0.1.3rc3 --no-cache-dir

and see if it's able to install?

[xcTorres]

It works. Thanks
