错误：无法为 numpy 构建轮子，错误：无法为 numpy 构建轮子，这是安装基于 pyproject.toml 的项目所必需的

Question

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.

Answer 1

I had this trying to install numpy with PyPy on macOS.

I solved the issue by first running brew doctor , which showed that my Command Line Tools (XCode) were outdated. Then I just followed the instructions to update them:

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

This solved the issue.

My configuration:

• macOS 12.2.1 Monterey

> python --version
Python 3.8.12 (9ef55f6fc369, Oct 25 2021, 05:10:01)
[PyPy 7.3.7 with GCC Apple LLVM 13.0.0 (clang-1300.0.29.3)]

Answer 2

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.
