yarn command not found in gitlab ci

Question

I am trying to configure my gitlab-ci to use yarn install instead of npm install

My current gitlab-ci.yml looks like:

image: node:6.9.4

cache:
  paths:
  - node_modules/
  - .yarn

before_script:
  - apt-get update -qq && apt-get install -qy libelf1

stages:
  - test

test_core:
  stage: test
  script:
  - yarn config set cache-folder .yarn
  - yarn install
  - npm run build
  - npm run test
  tags:
    - 2gb

But the build fails with the error: /bin/bash: line 48: yarn: command not found

is there something I am missing? I tried installing yarn with:

curl -o- -L https://yarnpkg.com/install.sh | bash

this gave me same error, probably because I need to reload the bash environment for the yarn command to become available.

The above config works perfect with npm install.

Please help me resolve this. If there is something missing in my config file or there is something wrong with the gitlab-ci. Thanks.

Answer 1

使用最新的官方节点docker镜像解决了这个问题。 由于图像：6.10.0，纱线默认安装在图像中。

但是如果您需要node-gyp来构建任何包，则需要通过在脚本中添加一行来安装它：

yarn global add node-gyp

Answer 2

安装纱线后，将以下内容添加到ci脚本中：

export PATH=$HOME/.yarn/bin:$PATH

Answer 3

我使用npx（程序包运行程序）解决了这个问题。最好仅为此目的扩展docker-image

npx yarn someCommand

Answer 4

我使用 image:node:latest 有时它会提示错误。 Clear Runner Caches 为我完成工作。也许跑步者在做其他工作后没有恢复到正确的状态。
