根据错误提示，安装 Paramiko 2.4.2 时出现了 `cryptography` 模块的错误。这是因为 `cryptography` 版本过低，需要升级到 2.2.2 及以上版本。

你可以先尝试升级 `pip` 版本：

pip install --upgrade pip

然后再安装 `cryptography` 模块：

pip install cryptography==3.4.8

最后再安装 Paramiko 2.4.2：

pip install paramiko==2.4.2

如果还是有问题，可以尝试升级 Python 版本或者使用其他 SSH 库来替代 Paramiko。

重新安装后,问题如下：Collecting paramiko==2.7.2 Using cached https://files.pythonhosted.org/packages/95/19/124e9287b43e6ff3ebb9cdea3e5e8e88475a873c05ccdf8b7e20d2c4201e/paramiko-2.7.2-py2.py3-none-any.whl Requirement already satisfied (use --upgrade to upgrade): bcrypt>=3.1.3 in /usr/lib64/python2.7/site-packages (from paramiko==2.7.2) Collecting pynacl>=1.0.1 (from paramiko==2.7.2) Downloading https://files.pythonhosted.org/packages/a7/22/27582568be639dfe22ddb3902225f91f2f17ceff88ce80e4db396c8986da/PyNaCl-1.5.0.tar.gz (3.4MB) 100% |████████████████████████████████| 3.4MB 19kB/s Complete output from command python setup.py egg_info: Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-build-RqQX6B/pynacl/setup.py", line 29, in <module> from setuptools.command.build_clib import build_clib as _build_clib ImportError: No module named build_clib ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-RqQX6B/pynacl/ You are using pip version 8.1.2, however version 23.1.2 is available.

根据你提供的信息，安装 Paramiko 依赖 PyNaCl 时出现了错误。错误信息显示缺少 `build_clib` 模块，可能是因为缺少 setuptools 包导致的。你可以尝试升级 pip 版本，然后再次运行安装命令：

pip install --upgrade pip
pip install paramiko

如果升级 pip 后仍然出现错误，可以尝试手动安装 setuptools：

pip install setuptools

然后再次运行 paramiko 的安装命令。希望这可以帮到你。

根据你提供的信息，安装Paramiko时出现了错误。错误信息中显示了以下内容：

SyntaxError: invalid syntax

这个错误提示是因为安装的bcrypt库版本不兼容当前的Python版本，或者是pip版本过低导致的。建议你更新pip到最新版本，使用以下命令：

pip install --upgrade pip

然后再重新安装Paramiko库：

pip install paramiko==2.7.2

如果问题仍然存在，请尝试先安装bcrypt库，再安装Paramiko库：

pip install bcrypt
pip install paramiko==2.7.2

这些方法中，更新pip或安装bcrypt库可能对你的问题有帮助，如果问题仍然存在，可以尝试升级Python版本或者联系Paramiko库的开发者来获取更多帮助。
