Root Cause

The identifier does not exist in the imported package (renamed, unexported, or the wrong package version). Often after a dependency upgrade.

generic

中文

所引用的标识符在导入的包中不存在（被重命名、未导出，或版本不对）。常见于依赖升级后。

Workarounds

  1. 90% success 
    go doc github.com/foo/bar.Bar
go doc github.com/foo/bar | grep -i bar
  2. 85% success 
    go get github.com/foo/[email protected]
go mod tidy

Dead Ends

Common approaches that don't work:

  1. 95% fail

    the symbol still does not exist in that package

  2. 100% fail

    undefined symbols are compile errors, not vet warnings

  3. 100% fail

    invalid syntax; cannot shadow package members
