dht.h: No such file or directory
时间: 2023-10-15 22:04:43 浏览: 49
如果提示找不到`dht.h`头文件,可能是您没有安装DHT库或者库文件没有正确安装。您可以尝试以下方法解决问题:
1. 安装DHT库
打开Arduino IDE,依次选择「工具」->「管理库...」,搜索「DHT」,找到并安装「DHT sensor library」或者「DHTlib」库。
2. 检查库文件安装路径
在Arduino IDE打开「文件」->「首选项」,在「Sketchbook位置」下面找到「libraries」文件夹,检查是否有「DHT」或者「DHTlib」文件夹,如果没有,可能是您的库文件安装路径不正确,您可以手动将库文件放在该文件夹下。
3. 检查头文件名
在您的代码中,`#include <dht.h>`应该是正确的头文件名,如果还是提示找不到头文件,您可以尝试将`dht.h`改成`DHT.h`,因为在一些库中头文件名可能是大写的。
希望这些方法能够帮到您,如果还有问题可以随时问我。

DHT.h: No such file or directory
It seems like you're encountering an error related to the DHT library in your code. This error message "DHT.h: No such file or directory" typically occurs when the compiler cannot find the header file for the DHT library.
To resolve this issue, you need to make sure that you have properly installed the DHT library and that it is accessible to your code. Here are a few steps you can try:
1. Check if you have installed the DHT library correctly. You can do this by going to the library's installation directory and verifying that the "DHT.h" file is present.
2. If the library is not installed, you need to download and install it. You can find the DHT library on platforms like Arduino IDE or GitHub. Make sure to follow the installation instructions provided by the library's documentation.
3. After installing the library, make sure that your code includes the correct path to the DHT.h header file. You can do this by adding the following line at the beginning of your code:
```cpp
#include <DHT.h>
```
4. If you have already included the header file in your code and are still getting the error, ensure that the file is located in a location where your compiler can find it. In some cases, you might need to move or copy the header file to a different directory or update the include path in your compiler settings.
By following these steps, you should be able to resolve the "DHT.h: No such file or directory" error and successfully compile your code.
fatal error: dht.h: No such file or directory
This error usually occurs when the compiler cannot find the header file "dht.h" that is required for your program. Here are a few possible solutions to resolve this error:
1. Check the file path: Make sure that the "dht.h" file is present in the correct directory. Double-check the file path and ensure that it is accessible.
2. Include the correct directory: If "dht.h" is located in a different directory than the one where your source file is, you need to include the directory in your compilation command. You can do this by adding the directory path with the "-I" flag, like "-I/path/to/directory".
3. Verify installation: If you are using a third-party library or module that includes "dht.h", make sure that it is installed properly. Follow the installation instructions provided by the library's documentation.
4. Update library dependencies: If you have recently updated your libraries or dependencies, make sure that they are up to date and compatible with each other. Incompatible versions of libraries can sometimes cause these types of errors.
By applying these solutions, you should be able to resolve the "fatal error: dht.h: No such file or directory" error and successfully compile your program.
