如何解决在ReactJS中重新加载路由是否需要页面刷新？
我已经使用browswerRouter为我的投资组合网站设置了一些路线（标记为Home | About |我做什么|经验的菜单链接）。
当我单击任何链接时，这些组件不会在页面上加载，或者至少它们不能正确呈现。为了让他们加载，我必须刷新页面。我知道这不是适当的行为。我还在学习React Router的方式。我需要帮助了解为什么会发生这种现象并解决此问题。下面是我使用的导入和我拥有的渲染设置。我只想重申一下，当我将页面路由到所需的组件后刷新页面时，它将正确呈现和加载。
谢谢编码员！

Network Upgrade for Ideal Nursing Services,Inc.: For
this project,I hired two other professionals to
assist with taking Ideal Nursing from a wired network
to a wireless network. Measurements of the building
were taken to create proper network diagrams for
approval by Ideal Nursing. Wires were removed and
Wireless Access Points (WAPs) were then installed and
configured. All machines were upgraded and/or
configured to connect to the WAPs. In addition,a new
rack with POE ports was installed in their server room
for their server,multi-port hub and router. This
created a more efficient working space and alleviated
unnecessary clutter.

当我检查其中任何一个时，控制台中什么都没有真正显示出来...
解决方法
我发现问题根本不是React Router的问题。实际上，这是我的style.css
.js .animate-box {
opacity: 0;
}
当路线渲染其组件时，不透明度分别自动设置为0。刷新页面后，将不透明度仅用作过渡。如果我注释掉不透明性，则显示的组件无需刷新页面
