Root Cause

The vendor directory does not exist or lacks required dependencies when using vendor mode.

generic

中文

使用 vendor 模式时，vendor 目录不存在或缺少必需的依赖项。

Workarounds

  1. 95% success Run 'go mod vendor' to populate the vendor directory. 
    Execute 'go mod vendor' in the module root to copy all dependencies.
  2. 90% success Use -mod=mod flag to bypass vendor mode. 
    Build with 'go build -mod=mod' to use module cache instead of vendor.

Dead Ends

Common approaches that don't work:

  1. Creating an empty vendor directory manually. 100% fail

    Go expects the vendor directory to contain all dependencies; empty directory causes build failures.

  2. Setting GOFLAGS=-mod=mod to ignore vendor. 30% fail

    This works but doesn't fix the vendor issue; it's a workaround, not a fix.
