PrismJS试图将您的Django模板标记处理为所选语言，我们可以告诉PrismJS忽略block, for example:中的内容
`

<pre><code class="language-none">{% image self.search_image thumbnail-400x200 as img %}
<img src="{{ img.url }}" alt="{{ img.title }}"></code></pre>

Now if we want to find a workaround for your case we could replace the spaces in your Django tags with   before you display them in PrismJS .

`

{% image self.search_image thumbnail-400x200 as img %}
<img src="{{&nbsp;img.url&nbsp;}}" alt="{{&nbsp;img.title&nbsp;}}">

与其说是一个答案，不如说是一个解决方案。我添加了以下函数来将这些空格放回：

const processDjangoCodeBlock = (element) => {
    const content = element.innerHTML;

    // Step 1: Insert whitespace after "{%" and "{{" 
    //         if the next character is not whitespace
    const step1Content = content.replace(/({%)(?!\s)/g, "$1 ")
        .replace(/({{)(?!\s)/g, "$1 ");

    // Step 2: Insert whitespace before "%}" and "}}" 
    //         if the previous character is not whitespace
    const step2Content = step1Content.replace(/(?<!\s)(%})/g, " $1")
        .replace(/(?<!\s)(}})/g, " $1");

    // Update the inner HTML of the element with the processed content
    element.innerHTML = step2Content;
};

不是很满意，因为我宁愿只是停止PrismJS剥离这些摆在首位。这个问题将潜伏在核心代码的某个地方，另一个世纪，当我有更多的时间。
调用模板是一个Wagtail块，如下所示：

<pre><code class="prism-block language-{{ self.language }}" 
      id="code-block-{{ block.id }}">{{ self.code }}</code></pre>

{% if self.language == "django" %}
    <script>
    document.addEventListener("DOMContentLoaded", () => {
        setTimeout(() => {
            processDjangoCodeBlock(
                document.getElementById("code-block-{{ block.id }}")
            );
        }, 0);
    });
    </script>
{% endif %}
