The problem is from where are you calling the jquery.jsfile.
I mean, it depends of where do you have your index.htmlfile.
问题是你从哪里调用jquery.js文件。我的意思是，这取决于您的index.html文件在哪里。
For example, if your index.html is on /app/index.html, try:
例如，如果您的 index.html 是 on /app/index.html，请尝试：
<script src="assets/javascripts/jquery.js"></script>

You don't need the full path, just assets/jquery.jsis enough:
您不需要完整路径，就assets/jquery.js足够了：
<script src="assets/jquery.js"></script>

I think that the most common place to define javascript files to add is the manifest file: app/assets/javasripts/application.js. It looks like this :
我认为定义要添加的 javascript 文件的最常见位置是manifest file: app/assets/javasripts/application.js。它看起来像这样：
//= require jquery
//= require jquery-ui
//= require jquery_ujs
Then you have your assets added application-wide .
然后，您将资产添加到应用程序范围内。
