解决方式

alias ibrew='arch -x86_64 /usr/local/bin/brew' # X86 Homebrew
ibrew install libssh2   # 本次安装的最新版本 stable 1.11.0
export LIBSSH2_DIR=$(ibrew --prefix libssh2)
export LDFLAGS="-L$LIBSSH2_DIR/lib"
export CFLAGS="-I$LIBSSH2_DIR/include"

pip uninstall -y pssh ssh2-python
pip install parallel-ssh==2.14.0 ssh2-python==1.1.2.post1 --no-cache-dir

安装完依赖的lib后，服务正常运行。

otool -L .env/lib/python3.9/site-packages/ssh2/session.cpython-39-darwin.so

.env/lib/python3.9/site-packages/ssh2/session.cpython-39-darwin.so:
	/usr/local/opt/libssh2/lib/libssh2.1.dylib (compatibility version 2.0.0, current version 2.1.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1311.100.3)

或者

python -c "from ssh2.session import Session; print('Success')"
