Root Cause

The 'go' directive in go.mod specifies a version string that does not follow the required semantic versioning format (e.g., '1.21' instead of '1.21.0').

generic

中文

go.mod 中的 'go' 指令指定了一个不符合所需语义版本格式的版本字符串（例如，'1.21' 而不是 '1.21.0'）。

Workarounds

  1. 95% success Correct the go directive to use proper semantic versioning (e.g., 1.21.0) 
    Edit go.mod: replace 'go 1.21' with 'go 1.21.0'
  2. 90% success Use 'go mod edit -go=1.21.0' to fix it automatically 
    go mod edit -go=1.21.0

Dead Ends

Common approaches that don't work:

  1. Changing the go directive to a non-existent version like '1.99' 80% fail

    Go only supports releases; non-existent versions cause the toolchain to fail to locate the proper standard library.

  2. Removing the go directive entirely 50% fail

    Without a go directive, the module defaults to an older version, potentially causing incompatibilities with newer language features.
