Root Cause

The go.mod file is malformed, possibly due to corruption or incorrect manual editing.

generic

中文

go.mod 文件格式错误，可能是由于损坏或手动编辑不正确。

Workarounds

  1. 90% success Restore go.mod from version control or a backup. 
    Use 'git checkout go.mod' or copy from a known good state.
  2. 80% success Recreate go.mod by running 'go mod init' and re-adding dependencies. 
    Backup current go.mod, delete it, run 'go mod init <module>', then 'go get' each dependency.

Dead Ends

Common approaches that don't work:

  1. Running 'go mod tidy' to fix the file. 100% fail

    Go cannot parse the file to begin with; tidy requires valid syntax.

  2. Adding random text to the end of go.mod to complete JSON. 100% fail

    Go.mod is not JSON; it's a custom format. Adding JSON will cause more errors.
