Error with examplePlugin

cd /usr/local/CyberCP/pluginInstaller && \\
python pluginInstaller.py remove --pluginName examplePlugin && \\
python pluginInstaller.py install --pluginName examplePlugin

I tried to run this command 6 times and get an error:


and

Also I want to ask is there a way to remove url and view because it’s just a background application after deleting the database (or another action).

Fix menu:

Line 81, add: + "
"
/cyberpanel-stable/pluginInstaller/pluginInstaller.py


`
writeToFile.writelines('<li><a href="{% url \\'' + pluginName + '\\' %}" title="{% trans \\'' + pluginName + '\\' %}"><span>{% trans "' + pluginName + '" %}</span></a></li>' + "\
")
`

And
Line 897, write all li tag in one line
/cyberpanel-stable/baseTemplate/templates/baseTemplate/index.html


`
<div class="sidebar-submenu">

    <ul>
        <li><a href="{% url 'installed' %}" title="{% trans 'Installed Plugins' %}"><span>{% trans "Installed" %}</span></a></li>
    </ul>

</div><!-- .sidebar-submenu -->
`

p/s:
How can I get POST variable from request (ex: preSubmitDBCreation) in file signals.py?
