[物联网] esp-idf 环境安装

2026.5 25

在复刻ESP32C3_4.2寸鱼鹰全反射类墨水屏的时候，需要用到esp-idf。

很多地方都是推荐离线安装，下载了2个离线文件。

esp-idf-tools-setup-offline-5.5.4.exe

eim-gui-windows-x64.exe 和archive_v5.5.4_windows-x64.zst

eim-gui-windows-x64.exe 是 esp-idf-tools-setup-offline-5.5.4.exe 的升级替代方案，前者是新一代统一安装管理器，后者是旧版离线安装包。

安装过程中遇到了很多错误。
错误1：

错误2：

最后发现是在C:\Espressif\tools下的 Microsoft.v6.0.1.PowerShell_profile.ps1 有语法错误。

文件：C:\Espressif\tools\Microsoft.v6.0.1.PowerShell_profile.ps1

把：$previous = $env:’_IDF.PY_COMPLETE’
改成：$previous = ${env:_IDF.PY_COMPLETE}

把：$env:’_IDF.PY_COMPLETE’ = ‘powershell_source’
改成：${env:_IDF.PY_COMPLETE} = ‘powershell_source’

把：$env:’_IDF.PY_COMPLETE’ = $previous
改成：${env:_IDF.PY_COMPLETE} = $previous

驱动签名问题：

重启系统禁用驱动签名

安装好esp-idf后，代码提示不兼容
