version flag is not working

[RoccoCloudCycle]

when I specify the version I want, even if it is the latest one, pipoe always fail with (No sdist package can be found error)

I can run the command without specifying the version, but for libraries that depend on specific version is problematic. For example, I can't install awsiotsdk, even without specifying the version, because it depends explicitly on awscrt v.0.14.0:

awsiotsdk
  | awscrt==0.14.0
  |  [ERROR] Failed to gather awscrt (No sdist package can be found.)

in get_package_info() when a version is specified the url = "https://pypi.org/pypi/{}/{}/json".format(package_name, version) will return a json response that doesn't contain "releases" field, so the following try block will always fails:

        try:
            version_info = next(
                i for i in info["releases"][version] if i["packagetype"] == "sdist"
            )
        except:
            raise Exception("No sdist package can be found.") 

it should be used always url = "https://pypi.org/pypi/{}/json".format(package_name)

plus line version = info["info"]["version"] will always override our desired version with the latest one

Replicates even with pipoe, using pipoe==2019.11

$ pipoe --package pipoe --version 2019.11

  pipoe==2019.11

I can confirm that this breaks pretty confusingly, especially when translating a requirement.txt create by pip freeze, etc.

The recipes can be created easily by removing the versions or calling on command line without specifying a version.
