如何制作携Paramiko模块的便携Python 2.7脚本？

Absolutely, this is totally feasible—you can bundle Paramiko and its required dependencies directly with your script, so your code can import the module from a local folder without needing to install anything on the target machines. Here's a step-by-step guide tailored to your Python 2.7.11 setup on Windows:

1. Gather Paramiko and Its Dependencies #

Paramiko doesn’t work alone—it relies on other modules like cryptography, pyasn1, and bcrypt (depending on the version). To grab all the necessary files:

• Open a command prompt and use Python 2.7’s pip to download the packages to a local folder. Run this command:

  pip install --download ./paramiko_lib paramiko
  

  This will download Paramiko and all its dependencies into a folder named paramiko_lib in your current directory.

2. Organize Your Folder Structure #

Arrange your files so your script can easily find the bundled modules. A clean structure looks like this:

my_portable_script/
├─ your_script.py  # Your main Python script
└─ paramiko_lib/
   ├─ paramiko/          # The Paramiko module folder
   ├─ cryptography/      # Required dependency
   ├─ pyasn1/            # Required dependency
   └─ ... (other downloaded dependency folders/files)

3. Modify Your Script to Use Local Modules #

At the very top of your_script.py, add code to add the local paramiko_lib folder to Python’s module search path. This tells Python to look for modules in your bundled folder first:

import sys
import os

# Get the absolute path to the local paramiko_lib folder
lib_path = os.path.join(os.path.dirname(os.path.abspath(__file__)), 'paramiko_lib')
# Add it to the front of sys.path so Python checks here first
sys.path.insert(0, lib_path)

# Now you can import Paramiko just like you normally would
import paramiko

4. Optional: Precompile Modules (For Speed/Source Hiding) #

If you want to precompile the .py files to .pyc (bytecode) for faster loading or to obfuscate the source a bit, run this command from your script’s root folder:

python -m compileall paramiko_lib/

This will generate .pyc files for all modules in the paramiko_lib folder. Important: Make sure the target machines are running the exact same Python 2.7 version (2.7.11) as your local setup—.pyc files are version-specific and won’t work across different Python 2.7 subversions.

5. Test Locally First #

Before deploying to remote machines, test your script locally to ensure it works without the system-wide Paramiko installation:

• Uninstall Paramiko from your local Python 2.7 environment (run pip uninstall paramiko).
• Run your script—if it imports Paramiko and runs correctly, you’re good to go.

Key Notes #

• System Compatibility: If your remote machines are also running Windows (matching your local setup), the downloaded dependencies will work fine. If remote machines use a different OS, you’ll need to download the OS-specific versions of the dependencies (some modules like cryptography have platform-specific binary components).
• Avoid Conflicts: By inserting the local lib path at the start of sys.path, you ensure Python uses your bundled modules instead of any existing system-wide versions (though you said remote machines don’t have Paramiko, so this is just a safeguard).
