Question

我有这个travis.yml，travis-ci.org抱怨它无法解析。

language: rust
rust:
  - 1.31.0
  - stable
  - beta
  - nightly
matrix:
  allow_failures:
    - rust: nightly
sudo: false
before_script:
  - rustup component add rustfmt
  - rustup target add thumbv7em-none-eabihf     # Any target that does not have a standard library will do
script:
  - cargo fmt --all -- --check
  - (rustup component add clippy && cargo clippy --all -- -D clippy::all) || true
  - cargo build
  - cargo test
  - cargo build --no-default-features --features alloc --target thumbv7em-none-eabihf # Test we can build a platform that does not have std.
  - cargo test --no-default-features --lib --tests # Run no_std tests
  - [[ $TRAVIS_RUST_VERSION != "1.31.0" ]] && cargo build --no-default-features --features alloc
  - cargo build --features unsealed_read_write # The crate should still build when the unsealed_read_write feature is enabled.
  - cargo build --no-default-features --features unsealed_read_write # The crate should still build when the unsealed_read_write feature is enabled and std disabled.

此文件属于https://github.com/pyfisch/cbor，显然引起解析失败的行是- [[ $TRAVIS_RUST_VERSION != "1.31.0" ]] && cargo build --no-default-features --features alloc。

Online Travis.yml validation没什么用（不推荐使用，已删除且无替换）。

需要进行哪些更改才能使Travis重新构建？

[字符在YAML中是特殊字符，与其他一些字符一样。如果您的字符串以它开头，则需要将其引号。

我建议对更长的字符串使用块标量。您可以使用文字量块标量，其将被直接使用：

- |
  [[ $TRAVIS_RUST_VERSION != "1.31.0" ]] && cargo build --no-default-features --features alloc

或折叠的块标量，使您可以将线分成多条线。它将与空格一起折叠：

- >
  [[ $TRAVIS_RUST_VERSION != "1.31.0" ]]
  && cargo build --no-default-features --features alloc
