ESP32 Forum

我是按照官方教程一步步走的，但在执行idf.py set-target esp32时出现报错：
CMake Error at build/CMakeFiles/git-data/grabRef.cmake:48 (file):
file failed to open for reading (No such file or directory):

D:/Programs/esp-idf/examples/get-started/hello_world/build/CMakeFiles/git-data/head-ref
我打开git-data文件夹，确实没有找到head-ref文件，里面只有grabRef.cmake文件和HEAD文件。即使不管报错继续执行idf.py build也无法编译，出现几乎相同的报错。百度完全没有查询到相关信息，也请大家和审核大大帮帮我 我不管是用什么教程都会遇到错误，编译不了例程 上次发的Visual Studio Code插件配置问题也没有人回复

以下是CMD内信息：

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

idf.py build

看LOG 信息 ，提示你需要更新子模块， 试过 git submodule update --init --recursive 这个命令了吗

试过了，可惜没什么变化 不过我用了VS Code插件，结合一篇github帖子的修改Build成功了，希望以后别再遇到问题:D

我最后按照https://www.bilibili.com/video/BV17p4y167uN?fro ... 337.0.0的教程，结合一点在github上看到的修改，build成功了例程，希望不要再遇到问题
如果在Build例程的时候第六百多步提示Generating x509_crt_bundle FAILED: esp-idf/mbedtls/x509_crt_bundle 然后下面写着Invalid certificate的话，按照https://github.com/espressif/esp-idf/issues/7621的回答来操作：Visual Studio里 查看-命令面板-搜索 SDK Configuration editor-在它的搜索栏里查询 Certificate-点掉Enable trusted root certificate bundle的勾 然后在它的搜索栏旁边点击保存 重新Build就可以pass掉这个错误 按照原回答所述，是因为有一些证书过期了，希望@乐鑫信息科技 能够修复一下
其他的问题我就不了解了[呆]我第一次用ESP-IDF 希望以后别遇到类似的bug了[笑哭]

后面证书的 fail 和你之前的 fail 是两回事，你最好一个归一个讲。
