[FIXED] ERROR: Failed building wheel for numpy , ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects

Issue

I`m using python poetry(https://python-poetry.org/) for dependency management in my project.

Though when I`m running poetry install, its giving me below error.

ERROR: Failed building wheel for numpy
  Failed to build numpy
  ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects

I`m having python 3.9 installed in my laptop.
I installed numpy 1.21.5 using pip install numpy, I even tried to down version it to 1.19.5.

Though I`m getting the same error.

I found out many people are getting ERROR: Failed building wheel for numpy this error in python 3.10, they solved it by down versioning python to 3.9, though that didnt working for me.

Solution

I solved it by doing the following steps:-

1. I updated the pyproject.toml(This file contains all the library/dependency/dev dependency)with the numpy version that I installed using pip install numpy command.

2. Run poetry lock to update poetry.lock file(contains details information about the library)

3. Run poetry install again, & it should work fine.

If you are having any problems, you can comment. I`ll try to answer it.
