【问题描述】:

使用 Github 操作发布 npm 包,它可以正常运行并运行 jest 测试用例而不会出错。所以我决定添加纱线缓存以优化构建时间并且缓存过程有效,但是开玩笑失败并出现以下错误。

$ jest --config=jest.config.js
/bin/sh: 1: jest: not found

【问题讨论】:

  • 你解决了吗?我怀疑问题是恢复缓存目录不会将笑话添加回 $path,因此需要手动添加或直接通过其 ./node_modules 路径调用

【解决方案1】:

我遇到了类似的问题,我提到了一些其他人的做法。也许试一试

- name: Cache dependencies
  uses: actions/cache@v1
  id: yarn-cache
  with:
    path: ${{ steps.yarn-cache-dir-path.outputs.dir }}
    key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
    restore-keys: |
      ${{ runner.os }}-yarn-
- name: Install Dependencies (from network)
  if: steps.cache-deps.outputs.cache-hit != 'true'
  run: |
    yarn policies set-version
    yarn install --frozen-lockfile --ignore-optional
- name: Install Dependencies (from cache)
  if: steps.cache-deps.outputs.cache-hit == 'true'
  run: |
    yarn policies set-version
    yarn install --frozen-lockfile --ignore-optional --offline

【讨论】:

  • 这解决了找不到命令的问题,但在时间上大大否定了缓存的好处。由于构建了新的包,在线和离线步骤都需要相似的时间来运行。
【解决方案2】:

您的管道仅缓存纱线的缓存,而不是 node_modules。 Jest 二进制文件应该在 node_modules 中,因此它(连同其他部门)不会从缓存中恢复。这是根据actions/cache 指导方针,建议缓存纱线缓存,然后执行yarn install

actions/setup-node 已经可以处理纱线缓存,无需为此滚动您自己的逻辑。

      - uses: actions/checkout@v2
      - uses: actions/setup-node@v2
        with:
          node-version: 12.x
          cache: yarn

      - name: Install dependencies
        run: yarn install --frozen-lockfile

      - run: yarn run test

如果真的要缓存 node_modules 而不是 yarn 的缓存,那就手动缓存目录

    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v2
        with:
          node-version: 12.x

      - uses: actions/cache@v2
        id: yarn-cache
        with:
          path: node_modules
          key: ${{ runner.os }}-node_modules-${{ hashFiles('**/yarn.lock') }}

      - name: Install dependencies
        if: steps.yarn-cache.outputs.cache-hit != 'true'
        run: yarn install --frozen-lockfile

      - run: yarn run test
