lazy静态的夜间构建在Travis CI上失败；由旧版本的rustc编译；

我的代码似乎运行良好，除了一个“由旧版本的rustc编译”的板条箱

缩短产量：

为什么lazy_静态板条箱在使用夜间编译器构建时失败

编辑：

.travis.yml

language: rust

rust:
    - nightly
    - beta
    - stable

cache:
    directories:
        - target

script:
    - cargo build --verbose
    - cargo test --verbose
    - cargo doc

after_success:
    test $TRAVIS_PULL_REQUEST == "false" &&
    test $TRAVIS_BRANCH == "master" &&
    test $TRAVIS_RUST_VERSION == "stable" &&
    sh etc/deploy-docs.sh

您的

.travis.yml

配置文件是什么样子的？您是否已将

目标

文件夹推送到存储库？@huon，啊，它可能正在使用以前的缓存目录？是的，不要缓存

目标

目录。为什么要将其添加到配置中？
