I have problem with using pip in unix. If I download a package, there is no prolbem to install it by :

sudo python setup.py install

But if I would like to install it by 

pip install "package"

I receive error:

Could not find a version that satisfies the requirement setuptools-scm (from versions: ) No matching distribution found for setuptools-scm /usr/local/lib/python2.7/dist-packages/pip-19.0.1-py2.7.egg/pip/vendor/urllib3/util/ssl.py:150: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings InsecurePlatformWarning Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLError(1, '_ssl.c:504: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version'),)) - skipping

Do you know where could be a problem please?

The error says about an SSL connection rejected. maybe it is some Host problem, but anyways, did you try with Python 3 pip3 install "package ?

First, You try 

sudo apt install python3-pip

Then, try:

pip3 install "package"
