Here's the relevant error: Where are the include headers stored? Would be helpful to also see |

Then that python is just broken 😢 The interpreter tells us that it should be inside "sysconfig_paths": {
"include": "{base}/local/include/python{py_version_short}",
},
"sysconfig_vars": {
"base": "/usr",
"py_version_short": "2.7"
},Which resolves to |

We can fall back to the distuils path to resolve this but I'd recommend opening an issue for whoever packages that Python 👍 because they're doing something wrong here 👍 |

This source of this RPM package can be found at: On Centos8 the Python.h is located where you expected: And an original Centos 6, the files are also as expected: But I wasn't able to find Python27 package for Centos 6 or Centos8 |

@tzulberti where you expected is actually where the following things says: So this might not necessarily be |

Thank you for solving the issue so fast. I tested it using the |
Issue
I try to install a package for python2 inside a virtualenv and the compilation fails mentioning that it can't find Python.h.
But, if I install the same package at the system level it can find that issue
I tested this with the lastest virutalenv release (20.0.12)
Environment
You can tests the build using this Dockerfile
And the error when building that dockerfile is:
Output of the virtual environment creation
Make sure to run the creation with
-vvv --with-traceback:Thank you for the amazing work
