安装requests模块时出现SyntaxError: invalid syntax，请求协助排查代码问题

Hey there! Let's troubleshoot that SyntaxError you ran into while trying to install requests. From what I've seen with similar issues, this almost always happens when you try running the pip command inside the Python interactive shell instead of your system's terminal or command prompt. Let's break this down:

• The Mistake: You probably opened up the Python REPL (the window with the >>> prompt) and typed pip install requests directly there. Python interprets everything in that shell as Python code, and pip isn't a valid Python statement—hence the syntax error.
• The Fix: First, exit the Python shell by typing exit() and hitting enter (or use Ctrl+D on macOS/Linux, Ctrl+Z on Windows). Then open your regular terminal/command prompt (the one where you can run system commands) and run pip install requests there. That should work smoothly.

• If you have both Python 2 and Python 3 installed, use pip3 install requests instead to make sure you're installing it for the right Python version.
• If you're using a virtual environment, don't forget to activate it first before running the install command—this ensures the package gets installed in the right place.
• Double-check for typos! Sometimes an extra space or missing character can throw off the command.

If you can share the exact line of code/command that triggered the error, I can help pinpoint it even better.
