Need help install pybind11 headers

Hello,

I tried to install pybind11 with development headers. I tried this, but does not work.

`

• name: pybind11
  buildsystem: simple build-commands:
  • python3.8 setup.py build
  • cmake -DPYBIND11_INSTALL=ON -DPYBIND11_TEST=OFF .
  • cmake --build .
  • python3.8 setup.py install --prefix=/app/ sources:
  • type: archive url: https://github.com/pybind/pybind11/archive/v2.6.2.tar.gz sha256: 8ff2fff22df038f5cd02cea8af56622bc67f5b64534f1b83b9f133b8366acff2`

The error is this. creating dist creating 'dist/pybind11-2.6.2-py3.8.egg' and adding 'build/bdist.linux-x86_64/egg' to it removing 'build/bdist.linux-x86_64/egg' (and everything under it) Processing pybind11-2.6.2-py3.8.egg creating /app/lib/python3.8/site-packages/pybind11-2.6.2-py3.8.egg Extracting pybind11-2.6.2-py3.8.egg to /app/lib/python3.8/site-packages Adding pybind11 2.6.2 to easy-install.pth file error: [Errno 30] Read-only file system: '/app/lib/python3.8/site-packages/easy-install.pth' Error: module pybind11: Child process exited with code 1

Any ideas? Thanks.
