AWS CodeBuild buildspec.yaml文件YAML_FILE_ERROR问题求助：Variables应为map类型

The error you're seeing (Expected Variables to be of map type: found string instead at line 5) stems from a simple YAML syntax mistake in your variables section.

The Root Cause #

YAML requires a space after the colon for valid key-value pair parsing. Your problematic line:

CRYPTOGRAPHY_DONT_BUILD_RUST:"1"

Lacks this space, so the parser treats the entire line as a single string instead of recognizing it as a key-value entry in the variables map.

Corrected Buildspec Configuration #

Here's the fixed version of your buildspec.yml, with the critical space added:

version: 0.2
env:
  variables:
    CRYPTOGRAPHY_DONT_BUILD_RUST: "1"  # Added space after colon to fix YAML parsing
phases:
  install:
    commands:
      - yum install python3 -y
      - python3 -m venv venv
      - source venv/bin/activate
      - curl https://sh.rustup.rs -sSf | sh -s -- -y
      - pip3 install -r requirements/local.txt

Quick YAML Syntax Tip #

For map entries (like your environment variables), always stick to the key: value format with a space after the colon. Quotes around values are optional here, but they're harmless to keep if you prefer consistency.
