根因分析

多个模块定义了重叠但冲突的 required_version 约束，导致无法选择满足所有要求的单一 Terraform 版本。

English

Multiple modules define overlapping but conflicting required_version constraints, making it impossible to select a single Terraform version that satisfies all.

解决方案

  1. Align all module required_version constraints to a single compatible range. For example, change all to required_version = ">= 1.6, < 2.0". Then run 'terraform init -upgrade' to reinitialize.
  2. If alignment is not possible, remove required_version from conflicting modules and rely on root module's constraint. Edit each module's versions.tf to delete the required_version line, then run 'terraform init'.

无效尝试

常见但无效的做法:

  1. 95% 失败

    Root module constraints are combined with child module constraints; overriding doesn't work because Terraform enforces intersection of all constraints.

  2. 70% 失败

    Removing constraints from child modules may cause them to be used with incompatible Terraform versions, leading to other errors. Terraform still validates root constraints.

  3. 85% 失败

    This doesn't resolve existing conflicts; it may introduce new ones if modules have different minimum version requirements.
