Yarn: command not found

[Adam Polak]

Since about 12PM we're receiving an error: 

bash: yarn: command not found

We're using default node:8 image

image: node:8
pipelines:
    default:
        - step:
            caches:
                - node
            script:
                - yarn install
                - yarn run flow
                - yarn run build
                - yarn run test --coverage --no-cache

 Does anything changed between 10AM and 12PM - last success build on the same pipelines config was at 10:20AM

For those having the same problem:

We had to change image from 

image: node:8

to

image: node:9.7.1

For me it turned out that I accidentally redefined $PATH in bitbucket pipelines environment variables, causing the same message. Took a while to figure it out...

Works with 

image: node:6.17.0

Alternatively, for anyone using an image that doesn't have yarn installed you can also install it as part of your build.

For example, add an installation command to your script such as:

- npm install yarn

- npm install -g yarn
