这可以通过添加_templates/versions.html 文件来覆盖rtd 主题的默认jinja template file 并在conf.py 文件中添加一些变量来实现。
执行以下命令创建一个新的 '_templates/' 目录和 'versions.html' 文件：
mkdir _templates
cat > _templates/versions.html <<'EOF'
{% if READTHEDOCS or display_lower_left %}
{# Add rst-badge after rst-versions for small badge style. #}
<div class="rst-versions" data-toggle="rst-versions" role="note" aria-label="versions">
<span class="rst-current-version" data-toggle="rst-current-version">
<span class="fa fa-book"> Read the Docs</span>
v: {{ current_version }}
<span class="fa fa-caret-down"></span>
</span>
<div class="rst-other-versions">
{% if languages|length >= 1 %}
<dl>
<dt>{{ _('Languages') }}</dt>
{% for slug, url in languages %}
{% if slug == current_language %} <strong> {% endif %}
<dd><a href="{{ url }}">{{ slug }}</a></dd>
{% if slug == current_language %} </strong> {% endif %}
{% endfor %}
</dl>
{% endif %}
{% if versions|length >= 1 %}
<dl>
<dt>{{ _('Versions') }}</dt>
{% for slug, url in versions %}
{% if slug == current_version %} <strong> {% endif %}
<dd><a href="{{ url }}">{{ slug }}</a></dd>
{% if slug == current_version %} </strong> {% endif %}
{% endfor %}
</dl>
{% endif %}
{% if downloads|length >= 1 %}
<dl>
<dt>{{ _('Downloads') }}</dt>
{% for type, url in downloads %}
<dd><a href="{{ url }}">{{ type }}</a></dd>
{% endfor %}
</dl>
{% endif %}
{% if READTHEDOCS %}
<dl>
<dt>{{ _('On Read the Docs') }}</dt>
<dd>
<a href="//{{ PRODUCTION_DOMAIN }}/projects/{{ slug }}/?fromdocs={{ slug }}">{{ _('Project Home') }}</a>
</dd>
<dd>
<a href="//{{ PRODUCTION_DOMAIN }}/builds/{{ slug }}/?fromdocs={{ slug }}">{{ _('Builds') }}</a>
</dd>
</dl>
{% endif %}
<hr/>
{% trans %}Free document hosting provided by <a href="http://www.readthedocs.org">Read the Docs</a>.{% endtrans %}
</div>
</div>
{% endif %}
EOF
并执行以下操作以追加到conf.py 文件：
cat >> conf.py <<'EOF'
