锚测试未连接到Local主机：8899
我运行了一个锚定初始化，锚固，然后部署。
我运行了“锚点运行测试”，即使我的本地验证器正在运行，我也会继续遇到此错误。 什么给？
错误：
初始化！： 错误：无法获得最近的Blockhash：Fetcherror：请求http：// localhost：8899/Failed，原因：Connect Econnrefused :: 1：88899
I ran an anchor init, anchor build, and then deployed.
I ran "anchor run test" I keep getting this error even though my local validator is running.
What gives?
Error:
Is initialized!:
Error: failed to get recent blockhash: FetchError: request to http://localhost:8899/ failed, reason: connect ECONNREFUSED ::1:8899

当我有其他运行验证器与测试的外壳时，我发生了同样的问题。该测试无法连接到Localhost：8899如果已经使用了。关闭另一个实例，然后运行“锚测试”，该实例将启动局部验证器并将其用于测试。
The same issue happened to me when I had a different shell running the validator vs the tests. The test can't connect to localhost:8899 if it is already in use. Close the other instance, then run 'anchor test', which will start a local validator and use it for the tests.
节点16而不是17。
当您获得“连接econnrefused :: 1：8899”错误时，请尝试使用
When you get "connect ECONNREFUSED ::1:8899" error, try using node 16 instead of 17 if you're on 17.
When you get "can't connect to localhost:8899 if it is already in use", try
