Root Cause

The version constraint string in the required_version block has a syntax error, such as mixing incompatible operators or using unsupported characters.

Workarounds

  1. 95% success Use a single valid constraint: `terraform { required_version = ">= 1.2" }` or `required_version = "~> 1.2"` without combining multiple operators. 
    Use a single valid constraint: `terraform { required_version = ">= 1.2" }` or `required_version = "~> 1.2"` without combining multiple operators.
  2. 85% success If combining constraints, use only compatible operators: `terraform { required_version = ">= 1.2, < 2.0" }` (both range operators) instead of mixing `~>` and `>=`. 
    If combining constraints, use only compatible operators: `terraform { required_version = ">= 1.2, < 2.0" }` (both range operators) instead of mixing `~>` and `>=`.

中文步骤

  1. Use a single valid constraint: `terraform { required_version = ">= 1.2" }` or `required_version = "~> 1.2"` without combining multiple operators.
  2. If combining constraints, use only compatible operators: `terraform { required_version = ">= 1.2, < 2.0" }` (both range operators) instead of mixing `~>` and `>=`.
  3. Validate the constraint syntax using `terraform version` command or an online HCL validator before applying.

Dead Ends

Common approaches that don't work:

  1. Adding a comma between constraints without checking operator compatibility (e.g., `~> 1.0, >= 1.2`) 60% fail

    The comma is allowed but the combination of `~> 1.0` (pessimistic) and `>= 1.2` can conflict; Terraform may reject ambiguous combinations.

  2. Using a single equals sign (e.g., `= 1.0`) instead of `~>` or `>=` 40% fail

    Single equals is valid but too restrictive; it doesn't cause the syntax error but may fail to match expected versions, leading to a different error.

  3. Removing all quotes around the version constraint string 95% fail

    Quotes are required for string values in HCL; removing them causes a parse error before version validation.
