Hi, I had the same problem. I managed to solve it by installing libssh2 with brew and setting up LDFLAGS and CPPFLAGS:

$ brew install libssh2

$ grep libssh2 ~/.zshrc
export LDFLAGS="-L${HOME}/brew/opt/libssh2/lib"
export CPPFLAGS="-I${HOME}/brew/opt/libssh2/include"

$ pip3 cache purge

$ pip3 install parallel-ssh
...

$ cat test.py
from pssh.clients import SSHClient

client = SSHClient(host='github.com', user='git', port=22, pkey='~/.ssh/github')
host_out = client.run_command('hostname')
for line in host_out.stdout:
    print(line)
for line in host_out.stderr:
    print(line)

$ python3 test.py

  You appear to be using ssh to clone a git:// URL.

had the same issue and with some modification went to success

need to change flags path

export LDFLAGS="-L$(dirname $(which brew))/../opt/libssh2/lib"
export CPPFLAGS="-I$(dirname $(which brew))/../opt/libssh2/include"

install cmake (obviously)

brew install cmake

after that i got another (openssl) error

CMake Error at /opt/homebrew/Cellar/cmake/3.25.1/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
        Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
        system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY
        OPENSSL_INCLUDE_DIR)

even tho openssl was in some obscure version, i did install it thru brew

brew install openssl

crate links

brew link --force openssl

and hallelujah ... installing parallel-ssh went finally ok and working (using fresh venv)

[FengJi2021]

both not working for me? any trouble shooting suggestion? i think this package using cpython to get openssl and problem shall be compiler lib link.
