使用一键安装命令安装PlateformIO MicroROS开发环境时报错

[l1]

报错代码如下

Processing featheresp32 (platform: espressif32; board: featheresp32; framework: arduino)
--------------------------------------------------------------------------------
Tool Manager: Installing espressif/toolchain-xtensa-esp32 @ 8.4.0+2021r2-patch5

是跟镜像问题相关吗？我在安装PlateformIO MicroROS开发环境前已经用一键安装命令更换了系统镜像源，并且根据视频教程【《ROS 2机器人开发从入门到实践》9.2.1开发平台介绍与安装】 https://www.bilibili.com/video/BV1pLf2YxEzv/?share_source=copy_web&vd_source=b55b762ce28a6ddb1537f871dc7d4a1d 配置完platformio.ini文件后，用

pio run

编译运行时下载速度也特别慢。求各位大佬指点下解决方法。
