我正在尝试按照本文所述将 Vue 和 Django 结合使用。除了 webpack-bundle-tracker 之外，一切似乎都在工作。我很确定 webpack-bundle-tracker 甚至没有安装，因为当我运行时会发生这种情况yarn add webpack-bundle-tracker --dev：

yarn add v1.22.4
info No lockfile found.
[1/4]   Resolving packages...
error An unexpected error occurred: "https://registry.yarnpkg.com/core-js: self signed certificate in certificate chain".

但是，当我运行npm install --save-dev webpack-bundle-tracker它似乎工作？但没有任何改变，也没有生成 webpack-stats.json 文件。

另一件事可能是 django-webpack-loader，因为当我运行时pip install django-webpack-loader会发出一堆权限错误，但是当我运行pip install django-webpack-loader --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org.

当我尝试打开我的 vue/django 测试页面时 django 给我的错误：

Error reading /Users/$ME/Dev/digiproj/vue_frontend/webpack-stats.json. Are you sure webpack has generated the file and the …

基本上我希望这是一个简单的问题，我只想检查查询集是否包含多个对象，但我不知道该怎么做？我写的（不起作用）如下。

{% if game.developer.all > 1 %} 
   <h1>Developers:</h1>
{% else %} 
   <h1>Developer:</h1>
{% endif %}

嘿，所以我尝试通过 npm ( sudo npm install -g @vue/cli) 安装 Vue，但我只是收到一堆警告和错误，我无法真正理解它，也不知道为什么会发生......
