esp32编译环境配置

1. 初步配置开发环境

Windows 平台工具链的标准设置
上面这个链接是官方详细配置说明，其实这里有2种安装方式，在安装前需要安装python命令(当时我安装的是python3.9)，最好安装好git.exe命令，本人当时安装的cmder.exe终端工具，。

• 1.安装方式1：
  下载exe安装器，这个需要很长时间
  https://dl.espressif.com/dl/esp-idf-tools-setup-2.3.exe
• 2.安装方式2：
  通过esp_idf源码目录下的安装命令安装，在命令行下执行install.bat即可安装，如果之前有安装其它旧版本的编译工具，这里会进行更新（记住这里，可以通过install.bat进行更新工具）。默认安装在C:\Users\username\.espressif
  
  下面是我的安装日志,安装完成后提示需要执行export.bat,linux是export.sh.执行这个命令，主要是把一些编译工具的环境变量配置到系统，方便我们在其他目录能够使用编译命令。

Setting up Python environment
Python 3.9.5
pip 21.1.2 from D:\espressif\python_env\idf4.4_py3.9_env\lib\site-packages\pip (python 3.9)
Installing Python packages from E:\board_project\esp32\esp-idf\requirements.txt
Looking in indexes: https://pypi.org/simple, https://dl.espressif.com/pypi
Processing e:\board_project\esp32\esp-idf\tools\kconfig_new\esp-windows-curses
  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.
