Error: link is a void element tag and must neither have `children` nor use `dangerouslySetInnerHTML`.

这个错误通常发生在你在一个空元素标签上使用了 `children` 属性或 `dangerouslySetInnerHTML` 属性。空元素标签是指没有内容的 HTML 标签,如 `<br>`、`<img>`、`<input>` 等。这些标签不支持包含子元素或设置内部 HTML。
要解决这个错误,你可以检查你的代码中是否在空元素标签上使用了 `children` 属性或 `dangerouslySetInnerHTML` 属性。如果有,你可以将它们移除或替换为适当的属性。
例如,如果你有以下代码:
```jsx
<br children="Hello World" />
```
你可以修改为:
```jsx
<br />
```
或者,如果你有以下代码:
```jsx
<input dangerouslySetInnerHTML={{ __html: '<span>Hello World</span>' }} />
```
你可以修改为:
```jsx
<input />
```
这样就可以避免这个错误。

tshark: "'icmp'" is neither a field nor a protocol name.
`tshark`是一款网络协议分析工具,它是Wireshark项目的一部分,用于抓取和解码网络包(Packet)。当你看到"icmp" 错误消息时,这意味着你在尝试解析的数据包中包含了ICMP(Internet Control Message Protocol,互联网控制报文协议)字段或数据包,但是`tshark`并未识别这个特定的字符串作为已知的字段名或内置协议。
ICMP是一个基础的网络协议,主要用于错误报告、路由信息查询等,但在`tshark`中查看它的内容时,你需要明确指定 ICMP 类型(例如 "icmp.type" 或 "icmp.code")或者是具体的ICMP报文名称(如"echo-request", "timestamp-reply" 等)。
如果你试图过滤特定的ICMP消息,正确的命令格式可能是:
```
tshark -D icmp.type=8 # 查看ICMP Echo Request (ping请求)
```
或者
```
tshark -r capture.pcap -T fields -e ip.src -e icmp.type # 显示IP源地址和ICMP类型字段
```
error: subscripted value is neither array nor pointer nor vector
This error message occurs when you try to use the subscript operator ([ ]) on a variable that is not an array, pointer, or vector.
For example, if you try to access a single character in a string using the subscript operator, but you forget to declare the string as an array or pointer, you will get this error.
Here's an example of incorrect code that would trigger this error:
```
int main() {
int x = 5;
x[0] = 10;
return 0;
}
```
In this example, we are trying to use the subscript operator on an integer variable "x", which is not an array, pointer, or vector. To fix this error, we need to declare "x" as an array or pointer first, like this:
```
int main() {
int x[5] = {1, 2, 3, 4, 5};
x[0] = 10;
return 0;
}
```
Now we have declared "x" as an array, and we can use the subscript operator to access its elements.
