Below is a screenshot of the error. 
下面是错误截图。
Also, below is what I get on localhost:8080
另外，下面是我在 localhost:8080 上得到的
By changing port numbers in server.xml (i.e. <Connector acceptCount="100" connectionTimeout="20000" executor="tomcatThreadPool" maxKeepAliveRequests="15" port="${bio.https.port}" protocol="org.apache.coyote.http11.Http11Protocol" redirectPort="${bio.https.port}"/>
), I get the same error with different port numbers.
通过更改 server.xml (ie <Connector acceptCount="100" connectionTimeout="20000" executor="tomcatThreadPool" maxKeepAliveRequests="15" port="${bio.https.port}" protocol="org.apache.coyote.http11.Http11Protocol" redirectPort="${bio.https.port}"/>
) 中的端口号，我得到了不同端口号的相同错误。

You have a application running on 8080, so you need to terminate whatever is running currently on 8080 port.
您有一个在 8080 上运行的应用程序，因此您需要终止当前在 8080 端口上运行的任何内容。
If you running Windows use:
如果您运行 Windows，请使用：
netstat -a -o | find "8080"
If you running Mac OS (which i think you are) use:
如果您运行 Mac OS（我认为您是），请使用：
sudo lsof -i :8080
Terminate that application and then launch Pivotal.
终止该应用程序，然后启动 Pivotal。
Otherwise you can change pivotal server port in the config file:
否则，您可以在配置文件中更改关键服务器端口：
<your tc server folder location>/conf/catalina.properties
Hope that helps.
希望有帮助。

Use TcpViewto kill the process on specfic port - Right click on the server and then click on "clean tc server work directory"
- Right click on the server and then click on "Clean"
- and there u go "baaaam"
更改服务器文件夹下 catalina.properties 文件中的端口号
例如
bio.http.port=
18080 bio.https.port=18844- 终止在端口 8080（或任何其他引起问题的端口）上运行的 java.exe -
使用TcpView 终止特定端口上的进程 - 右键单击服务器，然后单击“清理 tc 服务器工作目录”
- 右键单击服务器，然后单击“清理”

If you are using Eclipse under windows and you get this sort of problems - try killing javaw. [Alt+ Ctrl+ Del] -> Processes; kill javaw.
如果您在 Windows 下使用 Eclipse 并且遇到此类问题 - 尝试杀死 javaw。[ Alt+ Ctrl+ Del] -> 进程；杀死爪哇。
This is a quick fix without much thinking so use with caution.
这是一个没有太多思考的快速修复，因此请谨慎使用。
