使用Nginx服务Angular应用：js文件上的404

如何解决使用Nginx服务Angular应用：js文件上的404

我正在尝试使用Nginx提供Angular应用。

当我在location / {}块下提供应用程序时，一切正常，但是当我尝试将我的应用程序放在自定义路径块location /admin {}下时，我从每个.js文件（主要是404）中获取了404。 js，runtime.js等...）。

我的Angular应用程序的base-href是“ /admin”。

我在做什么错了？

即使添加了try_files $uri $uri/ /index.html，也没有任何反应。

在我的sites-available conf文件下面：

server {
    root /home/user/my_client/live/src;
    index index.html index.htm index.Nginx-debian.html;

    server_name myserver.com www.myserver.com;

    location /admin {
            alias /home/user/my_client/live/src;
            proxy_pass http://localhost:4200;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            try_files $uri $uri/ /index.html =404;
            index index.html;
    }

    location / {
            alias /home/user/omy_server/;
            proxy_pass http://localhost:3000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            client_max_body_size 25M;
    }
