hi:
   I cross compiled python2.7.10 and install python on my embedded device. But now, I may install pip on my embedded device.
   So, I did it as follow:
       1>I execute cmd:python -m ensurepip. It ocuurs errors as follow:
           Traceback (most recent call last):
            File "/usr/lib/python/lib/python27.zip/runpy.py", line 162, in _run_module_as_main
            File "/usr/lib/python/lib/python27.zip/runpy.py", line 72, in _run_code
            File "/var/app/python/libs/ensurepip.zip/ensurepip/__main__.py", line 4, in <module>

            File "/var/app/python/libs/ensurepip.zip/ensurepip/__init__.py", line 123, in bootstrap
            File "/var/app/python/libs/ensurepip.zip/ensurepip/__init__.py", line 45, in _run_pip
            File "/tmp/tmprHZPx4/pip-6.1.1-py2.py3-none-any.whl/pip/__init__.py", line 15, in <module>

            File "/tmp/tmprHZPx4/pip-6.1.1-py2.py3-none-any.whl/pip/index.py", line 30, in <module>
            File "/tmp/tmprHZPx4/pip-6.1.1-py2.py3-none-any.whl/pip/_vendor/__init__.py", line 92, in load_module
            ImportError: No module named 'pip._vendor.html5lib'
            The message "/tmp/tmprHZPx4/pip-6.1.1-py2.py3-none-any.whl" point out the pip package in that dir, while it is not there.
       2>As a result of the above error message, I download the pip-7.1.2 package and install it on my embedded device. It ocuurs errors as follow:
           # python setup.py install
               Traceback (most recent call last):
                File "setup.py", line 6, in <module>
                from setuptools import setup, find_packages
                ImportError: No module named setuptools
           #
       3> I I download the setuptools package and  execute cmd: python setup.py install.It ocuurs errors as follow:
           # python setup.py install
            Traceback (most recent call last):
             File "setup.py", line 6, in <module>
             from setuptools import setup, find_packages
             File "/var/app/python/libs/setuptools.zip/setuptools/__init__.py", line 12, in <module>
             File "/var/app/python/libs/setuptools.zip/setuptools/extension.py", line 8, in <module>
             File "/var/app/python/libs/setuptools.zip/setuptools/dist.py", line 19, in <module>
             ImportError: No module named pkg_resources
      So, where can i download the pkg_resources package. Is there somebody installed pip on embedded device? can you tell me how to do that?
