configure: error: cannot find libusb-devel 1.0
我安装了 libusb-dev 并再次运行配置，配置再次失败并出现相同的错误 我安装了 libusb-1.0-0-dev 并再次运行配置，配置再次失败并出现相同的错误 然后我进行了一些谷歌搜索，并尝试使用以下命令对 libusb 的安装进行一些调查
sudo dpkg -L libusb-1.0-0-dev

然后我尝试：
pkg-config --cflags --libs /usr/lib/arm-linux-gnueabihf/pkgconfig/libusb-1.0.pc
然后重新运行配置，但出现同样的错误，因此我也尝试了：
pkg-config --cflags --libs /usr/lib/arm-linux-gnueabihf/pkgconfig/libusb.pc
然后重新运行配置，但失败了，出现同样的错误，我还运行了：
`pkg-config --modversion libusb-1.0
1.0.20
pkg-config --modversion libusb
0.1.12
然后我卸载了 libusb-dev，只安装了 libusb-1.0-0-dev。然后尝试再次运行 configure，出现同样的错误。
configure: error: cannot find libusb-devel 1.0
然后我尝试添加到~.bashrc
PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/lib/arm-linux-gnueabihf/pkgconfig/libusb-1.0.pc
这是怎么回事，想不通，希望能得到一些帮助

答案1
尝试：
pkg-config --modversion libusb-dev
我不认为 pkg-config-path 是一个命令。有一个 PKG_CONFIG_PATH 环境变量。
答案2
由于某些奇怪的原因，这个“pymini”包没有尝试正确发现 libusb 本身的路径或其他标志。您需要为此给它一些额外的标志，您可以在 configure.ac 的注释中看到引用
# Notes on compiling on Ubuntu.
#
# ./configure --prefix=/usr CFLAGS="-g -Wall -I/usr/include/libusb-1.0" CXXFLAGS="-g -Wall -I/usr/include/libusb-1.0" (Ubuntu 12.04)
#
# make
# make install
你走在正确的轨道上。libusb-1.0-0-dev 是你需要的包（而不是 libusb-dev，它们是不同的），此时上面 configure.ac 中的命令应该可以按原样工作。
您尝试使用 pkg-config 的“更好”版本将是这样的。
pkg-config libusb-1.0 --cflags
./configure --prefix=/usr CFLAGS="$(pkg-config libusb-1.0 --cflags)" CXXFLAGS="$(pkg-config libusb-1.0 --cflags)"
通常您还会设置 LIBS=$(pkg-config libusb-1.0 --libs)，但是这已经硬编码到该项目中，因此在这种特定情况下不需要它。
