ESP-IDF 4.4例程hello_world编译失败的原因？

问答对人有帮助，内容完整，我也想知道答案 0 头一次接触硬件，跟着官方的快速入门一步步走到build这里开始报错，Code: Select all idf.py menuconfig 步的菜单和之前的步骤都没问题，但是到编译这里开始报错，一开始好像是内存问题，把内存设置成16MB之后就变成下面这样，求大神指点一下 Code: Select all D:Espressifesphello_world>idf.py build Executing action: all (aliases: build) Running ninja in directory d:espressifesphello_worldbuild Executing "ninja all"...
