rpmvenv failing and complaining about 'time' module not existing.

Hello,

When I run rpmvenv to package my python library I get a wierd error saying it was not possible to import the library ‘time’.

Although if I create a virtual env myself and import time, it works just fine.

This is for CentOS Linux 7 (Core)

The json file, for now, is pretty basic (almost equal to the one in the example):

{
    "extensions": {
        "enabled": [
            "python_venv",
            "blocks"
        ]
    },
    "core": {
        "group": "Application/System",
        "license": "MIT",
        "name": "myRPM",
        "summary": "short package summary",
        "version": "1.0"
    },
    "python_venv": {
        "name": "venv",
        "path": "/usr/share/myPathRPM/"
    },
    "blocks": {
        "desc": [
            "some long package description",
            "each array element is a new line"
        ]
    }
}

And the output is:

RPM build errors:

Any help please?

Thank you!

Does the same error occur if you manually run virtualenv with the same --always-copy flag that rpmvenv uses? I believe this may actually be a bug in the recent release of virtualenv. Reference: https://github.com/pypa/virtualenv/issues/565

I’m glad we could figure it out! Let me know if you have any more trouble.
