我刚开始使用 HerokuCI。我有一些 Selenium 测试，所以我在我的app.json.

{
  "buildpacks": [
    { "url": "heroku/ruby" }
  ],
  "environments": {
    "test": {
      "addons": ["heroku-postgresql:in-dyno", "heroku-redis:in-dyno"],
      "buildpacks": [
        { "url": "heroku/ruby" },
        { "url": "https://github.com/notvad/heroku-buildpack-selenium" },
        { "url": "https://github.com/heroku/heroku-buildpack-chromedriver" },
        { "url": "https://github.com/heroku/heroku-buildpack-google-chrome" }
      ],
      "env": {
        "REDIS_PROVIDER": "REDIS_URL",
        "RAILS_ENV": "test",
        "RACK_ENV": "test",
        "MALLOC_ARENA_MAX": 2,
        "LANG": "en_US.UTF-8",
        "TEST_API": 1
      },
      "scripts": {
        "test-setup": "./bin/setup-cc-test-reporter",
        "test": "./bin/test-with-cc-test-reporter"
      }
    }
  }
}

这些与所有依赖项一起不断重建。

这占用了大部分测试运行时间。

这些安装可以缓存吗？

如果您按照此处所述启用了缓存，则似乎您可以做更多的事情来缓存安装。如果这是一个严重的问题，您总是可以指向您从远程存储库克隆的本地包以加快速度。

经过各种搜索和尝试，我带来了好消息。

关键问题是您在日志文件中的错误，例如：

bash: /tmp/buildpacks/b5ae60a477f2ba582d00a4ba23348059d40dea69cea6d982947f7c6afa72d2b8d69252449d43cbcf97a23341fd57300a3fef3224ace95482e1c0deaf8a844e4d/export: No such file or directory

这个自动生成的目录显然是一个缓存目录，不固定时自动生成的。

例如，这可以在app.json文件中定义的heroku-buildpack-selenium buildpack 中确认：

# parse and derive params
BUILD_DIR=$1
CACHE_DIR=$2
LP_DIR=`cd $(dirname $0); cd ..; pwd`

我发现的这个官方文档证实了这一点：

CACHE_DIR 的内容将在构建之间持久化。您可以在此处缓存依赖解析等长流程的结果，以加快未来的构建。

所以关键的解决方案是在你的安装中定义这个CACHE_DIR变量；所以我猜它要么直接在您的app.json文件中，要么直接在您的GitHub Hook中。

如果您需要进一步的帮助，请告诉我。
