检查文件夹结构
首先看README文件，看文件夹组织结构是否正确
This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
(“lib/your_library_name/[here are source files]”).
For example, see a structure of the following two libraries Foo and Bar:
|–lib
| |
| |–Bar
| | |–docs
| | |–examples
| | |–src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |–Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|–src
|- main.c
and a contents of src/main.c:
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
PlatformIO Library Dependency Finder will find automatically dependent
libraries scanning project source files.

设置 platformio.ini 配置文件
如果编译仍然报错，可能是你在 lib 文件夹中的库相互包含了，可以参考官方说明文档。链接
阅读官方文档后，我在 platformio.ini 文件中添加这一行就解决问题了
lib_ldf_mode=deep+
如图
