title: Is there any way to solve launch anaconda-navigation falid:AttributeError: 'NoneType' object has no attribute 'get'
body: <p>yesterday，I update my anaconda-navigator,I execute the followoig code in Anaconda Prompt:</p>
  <pre><code>conda update anaconda-navigator
  anaconda-navigator --reset
  conda update anaconda-client
  </code></pre>
  <p>then.I could not open anaconda-navigator,and I get the following code:</p>
  <pre><code>    (base) C:\Users\liyong01&gt;anaconda-navigator
  Traceback (most recent call last):
    File &quot;D:\Anaconda\Anaconda3\lib\site-packages\anaconda_navigator\widgets\main_window\__init__.py&quot;, line 530, in setup
      user = self.components.accounts.detect_new_login()
    File &quot;D:\Anaconda\Anaconda3\lib\site-packages\anaconda_navigator\widgets\main_window\account_components.py&quot;, line 409, in detect_new_login
      self.detect_enterprise_org_login(conda_rc)
    File &quot;D:\Anaconda\Anaconda3\lib\site-packages\anaconda_navigator\widgets\main_window\account_components.py&quot;, line 395, in detect_enterprise_org_login
      ae4_api_url).netloc == parse.urlparse(conda_rc.get('channel_alias', '')).netloc
  AttributeError: 'NoneType' object has no attribute 'get'
  </code></pre>
  <p>following the information,I find the account_components.py and <strong>init</strong>.py ,but there is nothing,
  so,Is there anyone could help me,In the web stackoverflow,there are many similarity problems,but the reason of problem is different.</p>
