无法在Thonny中安装Biopython，遇Python.h缺失及pip未找到问题

一、Thonny中安装Biopython的报错 #

执行安装后出现编译错误，具体信息如下：

-I/Library/Frameworks/Python.framework/Versions/3.10/include/python3.10 -c Bio/Align/_aligners.c -o build/temp.macosx-10.9-universal2-cpython-310/Bio/Align/_aligners.o
      Bio/Align/_aligners.c:11:10: fatal error: 'Python.h' file not found
      #include "Python.h"
               ^~~~~~~~~~
      1 error generated.
      error: command '/usr/bin/clang' failed with exit code 1
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> biopython

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
Process returned with code 1

核心错误为*'Python.h' file not found*，导致clang编译失败。

二、bash终端手动安装的报错 #

在终端执行安装命令时，出现命令未找到提示：

pip install Biopython
-bash: pip: command not found

已尝试的解决操作 #

• 重新安装Thonny，但问题仍未解决

补充说明：Thonny是面向初学者的Python IDE
