Root Cause

The current working directory does not contain a go.mod file, and no parent directory has one, so Go cannot determine the module context.

generic

中文

当前工作目录不包含 go.mod 文件，且任何父目录都没有，因此 Go 无法确定模块上下文。

Workarounds

  1. 95% success Initialize the module with 'go mod init' 
    go mod init example.com/project
  2. 90% success Navigate to a directory that contains a go.mod file 
    cd /path/to/valid/module && go build

Dead Ends

Common approaches that don't work:

  1. Creating a go.mod file with arbitrary content 70% fail

    The module path must be correct; arbitrary content may cause import resolution failures.

  2. Setting GO111MODULE=off to use GOPATH mode 60% fail

    If the project is not in GOPATH, it still fails; also disables modern module features.
