在travis-ci上使用balena-cli (balena build)构建

Question

我一直在尝试为我的balena构建在travis上设置一个CI环境。我已经成功地在travis的环境中安装了balena-cli，但似乎无法在qemu环境中构建。我将使用--debug标志获取此日志

[debug] new argv=[/home/travis/.nvm/versions/node/v12.21.0/bin/node,/home/travis/build/vivitek/deep-thought/node_modules/.bin/balena,build,--deviceType,raspberrypi3-64,--arch,aarch64,--emulated] length=8

.travis.yml如下所示：

sudo: true
language: node_js
node_js:
  - "12"
branches:
  only:
    - develop
    - master
    - ROUT-44-continuous-integration
git:
  submodules: false
cache:
  directories:
    - node_modules
before_script:
  - npm i -g balena-cli
jobs:
  include:
    - stage: "build rpi4"
      name: "Building on raspberry pi 4"
      script: ./build_rpi4.sh
    - stage: "build rpi3"
      name: "Building on raspberry pi 3"
      script: ./build_rpi3.sh

脚本buiöd_rpi4.sh如下所示：

 #!/usr/bin/env sh

echo -e "Building containers in emulated containers"
balena build --deviceType raspberrypi3-64 --arch aarch64 --emulated --debug

build_rpi3.sh看起来基本是一样的，只是标志改变了。

有人知道可能出了什么问题吗？

默认情况下，balena CLI将在$HOME/.balena中缓存下载的资产(比如--emulated的QEMU )，而且主目录看起来在Travis-CI中不存在。

您可以通过首先在您的环境中设置BALENARC_DATA_DIRECTORY来更改balena CLI数据目录。因此，在您的Travis工作区中将其设置为绝对路径，我假设它会起作用。
