Could not find directory of OpenSSL installation, and this `-sys` crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the `OPENSSL_DIR` environment variable for the
compilation process.
Make sure you also have the development packages of openssl installed.
For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.
If you're in a situation where you think the directory *should* be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.
$HOST = x86_64-unknown-linux-gnu
$TARGET = x86_64-unknown-linux-gnu
openssl-sys = 0.9.48
It looks like you're compiling on Linux and also targeting Linux. Currently this
requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`
could not be found. If you have OpenSSL installed you can likely fix this by
installing `pkg-config`.

#通过libssl.so.1.1 => /usr/lib/x86_64-linux-gnu/libssl.so.1.1 (0x00007fa72fe20000)知道OPENSSL_LIB_DIR是 /usr/lib/x86_64-linux-gnu
代码语言：javascript复制# find / -name "openssl" | grep include
find: /usr/include/openssl知道OPENSSL_INCLUDE_DIR是/usr/include/openssl 编辑.bashrc，添加：
代码语言：javascript复制export OPENSSL_INCLUDE_DIR=/usr/include/openssl
export OPENSSL_LIB_DIR=/usr/lib/x86_64-linux-gnu然后
代码语言：javascript复制source ~/.bashrc
cargo install cargo-generate这个时候就可以成功
