DRM4G intallation problem

[antonio]

I'm just tried to install DRM4G in my Ubuntu box, but I'm getting this error

antonio@xps:~$ pip install drm4g
Downloading/unpacking drm4g
  Could not find a version that satisfies the requirement drm4g (from versions: 2.5.0b1)
Cleaning up...

Storing debug log for failure in /home/antonio/.pip/pip.log

I had the same error. I solved it by updating pip:

sudo pip install --upgrade pip

And remember that if you're not adding any installation options or doing it in a virtual environment you need to run sudo pip install drm4g.

I have made a sudo installation, and it said Success, but I'm getting some error messages:

antonio@xps:~$ sudo pip install drm4g

The problems you're having are related with your versions of python and your virtual environment. They can be ignored since they don't affect the installation process.

To solve the problem about not owning the directory, just follow their indications, use sudo's -H flag, and choose a directory owned by you.

One solution for solving the SNIMissingWarning and InsecurePlatformWarning warnings is to upgrade to a more recent version of Python..

If for any reason you are not able to upgrade, you can also run pip install 'requests[security]' as explained ​here.

You can also check ​here for a bit more information about those warnings.
