我在 Ubuntu 18.04 中遇到了 wifi 范围问题。我从 GitHub 下载了 Realtek 驱动程序软件，然后将文件解压到桌面并运行 make 命令。
allen@allen-HP-Notebook:~/Desktop/rtlwifi_new-rock.new_btcoex$ make
运行此命令后，出现以下错误。
make -C /lib/modules/4.15.0-33-generic/build M=/home/allen/Desktop/rtlwifi_new-rock.new_btcoex modules
make[1]: Entering directory '/usr/src/linux-headers-4.15.0-33-generic'

为什么我会收到这个错误？
