我尝试使用sudo apt-get install libdouble-conversion-dev安装libdouble conversion dev包，但失败，输出如下：
Package libdouble-conversion-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libdouble-conversion-dev' has no installation candidate
我之前也尝试过运行sudo apt-get update，并得到了相同的结果，以及从https://packages.debian.org/buster/amd64/libdouble-conversion-dev/download但似乎什么都没有改变。
您可以在兼容sudo dpkg -i $name_of_package_file的Ubuntu主机上手动安装Debian软件包。
