【问题描述】：

我有一些全局包，例如无服务器框架、ESLint 等。我已经为 yarn 实现了 GitHub Actions 缓存。下面是我的代码。

- uses: actions/cache@v1
  id: yarn-cache # use this to check for `cache-hit` (`steps.yarn-cache.outputs.cache-hit != 'true'`)
  with:
    path: $ steps.yarn-cache-dir-path.outputs.dir 
    key: $ runner.os -yarn-$ hashFiles('**/yarn.lock') 
    restore-keys: |
      $ runner.os -yarn-

- name: Adding serverless globally
  run: yarn global add serverless

- name: Yarn Install
  if: steps.yarn-cache.outputs.cache-hit != 'true'              
  run: |
    echo "cache hit failed"
    yarn install
  env:
    CI: false

但是我的全局包没有被缓存。有没有办法缓存 Yarn 全局变量？

【问题讨论】：

为什么在“Yarn Install”步骤中将CI 环境变量设置为false？

@Edric 这是一个错误。我刚刚复制了我的 yarn 构建块并为 Yarn Install 重命名。

您是否关注tutorial 启用了纱线包的缓存？

@smac89 是的，我做到了。纱线缓存工作正常。问题在于纱线全局缓存。并且在将一些纱线包安装为全局之后，github操作也无法调用它。所以我目前正在使用 NPM 进行全局安装。但是缓存仍然不起作用。

我正在粘贴解决方案的构建文件，

    push:
        branches:
            - dev

        branches:

        steps:

            - name: NODE SETUP ACTION
              uses: actions/setup-node@v1
              with:
                  node-version: '12.x'

                  yarn config set global-folder $(yarn cache dir)

              uses: actions/cache@v2
              env:
                  cache-version: v1
              id: yarn-cache
              with:
                  path: |
                      $ steps.yarn-cache-dir-path.outputs.dir 
                      **/node_modules
                  key: $ runner.os -yarn-$ env.cache-version -$ hashFiles('**/yarn.lock') 
                  restore-keys: |
                      $ runner.os -yarn-$ env.cache-version -
                      $ runner.os -yarn-
                      $ runner.os -

            - name: Installing dependencies
              if: steps.yarn-cache.outputs.cache-hit != 'true'
              run: |
                  echo "YARN CACHE CHANGED"
                  yarn install

            - name: Adding serverless globally
              if: steps.yarn-cache.outputs.cache-hit != 'true'
              run: |
                  echo "NO CACHE HIT"
                  yarn global add serverless

我为这些步骤命名，以便他们可以理解。

这会抛出：The 'add-path' command is disabled. Please upgrade to using Environment Files or opt into unsecure command execution by setting the 'ACTIONS_ALLOW_UNSECURE_COMMANDS' environment variable to 'true'.
