conan: Conan install cmd Errors on using options (-o).

Ref: https://github.com/conan-io/conan/issues/1556 my last entry on this ERROR issuing conan info

As per Ref above, Lib1 was packaged with conan package_files and using options with config @memsharded suggested in Ref above.

As next step I’m trying to consume Lib1 by issuing a simple conan install but this also erroring. Below is my config for the consumer, the Conan cmd and the Error output.

conanfile.py

from conans import ConanFile
import os

class ConsumerConan(ConanFile):
    name = "Consumer"
    channel = "testing" 
    version = "1.0.0"   
    description = "Consumer"
    author = "user"
    url = "http://"
    license = "BSD"
    options = { "variations": ['d1', 'd2', 'd3'] }

    def requirements(self):
        self.requires("Lib1/1.2.4@user/testing" )

    def imports(self):
      self.copy("*", dst="inc", src="inc", root_package="Lib1") 
      self.copy("*", dst="lib", src="bin", root_package="Lib1")

install.py for the Consumer’s conanfile

import os, shutil, sys

os.system("conan install . -o Lib1:variations=d1 -o variations=d1") 

Error
