问题描述

每当我的工作运行时,他们总是需要大约 40 秒来下载和安装 libreoffice。我将把它存储到缓存中并恢复缓存以在下一个工作中重用它。

      - restore_cache:
          key: cache-libre-6.3-b             # Restore libreoffice
      - run:
          name: install libreoffice 6.3
          command: |
            if [[ ! -d /opt/libreoffice6.3/ ]]; then
                # download & install the .deb
                mkdir -p /tmp/libreoffice
                l=download.tar.gz
                cd /tmp/libreoffice
                  wget -O $l https://download.documentfoundation.org/libreoffice/stable/6.3.3/deb/x86_64/LibreOffice_6.3.3_Linux_x86-64_deb.tar.gz
                  tar -xvf $l
                  d=`ls -td */ | head -n1`
                  cd $d/DEBS/
                  sudo dpkg -i *.deb
                cd -

                # install dependencies required when run :soffice binary  ref. https://github.com/microsoft/vscode/issues/13089
                sudo apt update
                sudo apt install -y libxinerama1 libgtk2.0-0 libxss-dev libgconf-2-4 libasound2

            fi
            # make :libreoffice softlink to libreoffice binary 6.3
            sudo ln -s /opt/libreoffice6.3/program/soffice /usr/bin/libreoffice
            sudo chmod -R 777 /opt/libreoffice6.3/
      - save_cache:
          key: cache-libre-6.3-b
          paths:
            # Save cache libreoffice
            - /opt/libreoffice6.3/
            - /home/circleci/cache-libre

当我再次重新运行作业时,我无法恢复缓存。我在下面得到了一些权限被拒绝:

Found a cache from build 7593 at cache-libre-6.3-b

  * /opt/libreoffice6.3

我该如何解决这个问题。

解决方案


这也发生在我最近。鉴于我有很多构建使用该密钥保存和恢复该缓存,然后它可能是间歇性的,这不太可能是直接原因;但是,我会提到这一点,以防它碰巧帮助人们。

我以前一直在使用该working_directory命令来尝试使用persist-to-workspaceandattach_workspace并认为这可能会导致问题。

可能导致错误的序列:

  • 建个:

    1. 设置工作目录working_directory: ~/tmp
    2. 使用键 X 保存缓存
  • 构建 B:

    1. 默认工作目录(未使用working_directory命令)
    2. 尝试使用相同的键 X(但不同的工作目录)恢复缓存
    3. Error untarring cache: Error extracting tarball

修复它的解决方案只是更改缓存键。比如从v1前缀到v2。这避免了尝试恢复为tmp要尝试将工作目录恢复到不同工作目录的缓存。它现在使用一个新鲜的。
