我尝试运行以下代码读取HID设备：

import hidapi

# Find the device
devices = hidapi.DeviceManager().devices()
for device in devices:
    if device.vendor_id == 0x2341 and device.product_id == 0x0042:
        gamepad = device
        break

# Read data from the device
data = gamepad.read(64)
print(data)

已通过pip3 install hidapi成功安装模块，但运行代码时仍提示ModuleNotFoundError: No module named 'hidapi'，命令行操作记录如下：

PS C:\Users\felix\OneDrive\Desktop\UE5 Space Ship Project> pip3 install hidapi

运行环境：Windows 11、Python 3.12.6

• 确认Python与pip的对应关系
  问题大概率是pip3安装的模块和python命令调用的解释器不是同一个版本。执行以下命令检查版本是否一致：

  python --version
  pip3 --version
  

  如果版本不匹配，改用python -m pip install hidapi安装模块，这会确保模块安装到当前python命令对应的解释器环境中。

• 验证模块安装路径
  Windows下用户级安装的模块默认路径为C:\Users\felix\AppData\Roaming\Python\Python312\site-packages，检查该目录下是否存在hidapi相关文件。
  也可以在代码开头添加以下内容，查看Python加载模块的路径列表，确认是否包含上述用户目录：

  import sys
  print(sys.path)
  

  如果路径中没有用户目录，可手动添加：

  import sys
  sys.path.append(r'C:\Users\felix\AppData\Roaming\Python\Python312\site-packages')
  import hidapi
  

• 使用Python完整路径运行
  直接调用Python安装目录下的python.exe运行脚本，确保使用的是安装了hidapi的解释器：

  C:\Python312\python.exe "c:\Users\felix\OneDrive\Desktop\UE5 Space Ship Project\HID_test.py"
  

• 检查虚拟环境
  如果当前项目使用了虚拟环境，需要先激活虚拟环境，再重新安装hidapi并运行脚本。
