title: my python package can be installed on my local conda env but can not be installed on other envs or systems
body: <p>I have created my own python package and uploaded it in <a href="https://test.pypi.org/" rel="nofollow noreferrer">https://test.pypi.org/</a> which installed and worked fine in my conda virtual environment but when I want to install it on other systems or environments, it seems that it cant install the dependencies.
  i get this error:</p>
  <pre><code>ERROR: You must give at least one requirement to install (see &quot;pip help install&quot;)
