linux - 如何在 gitlab ci :bad substitution 中修复 bash

Question

package.json 文件中的脚本 block :

"scripts": {
  ...
  "test:schema": "./src/schemas/schema-test.sh"
}

.gitlab-ci.yml 文件内容:

image: node:12

stages:
  - lint
  - test
  # - build

.yarn_install:
  before_script:
    - yarn config set @private:registry https://npm.private.io
    - echo "//npm.private.io/:_authToken=${NPM_TOKEN}" > ~/.npmrc
    - yarn install
    - export PATH="./node_modules/.bin:${PATH}"

prettier:
  stage: lint
  script:
    - yarn config set @private:registry https://npm.private.io
    - echo "//npm.private.io/:_authToken=${NPM_TOKEN}" > ~/.npmrc
    - yarn add prettier
    - yarn lint

schema test:
  stage: test
  script:
    - yarn test:schema

variables:
  GIT_DEPTH: 10

schema-test.sh 文件内容:

#/usr/bin/env bash

# Test all file ends with schema.json via ajv

CURRENT_DIR=`dirname "$0"`

cd $CURRENT_DIR

for SCHEMA_FILE in *.schema.json
do
    SAMPLE_FILE=samples/${SCHEMA_FILE/schema/sample}
    echo Schema file: $SCHEMA_FILE
    if [ -f $SAMPLE_FILE ]
    then
        echo Found sample file: $SAMPLE_FILE
        npx ajv -s $SCHEMA_FILE -d $SAMPLE_FILE
    else
        echo "*NO* sample file found for $SCHEMA_FILE"
    fi
done

Gitlab CI 错误信息:

...
51 $ export PATH="./node_modules/.bin:${PATH}"
52 $ yarn test:schema
53 yarn run v1.21.1
54 $ ./src/schemas/schema-test.sh
55 ./src/schemas/schema-test.sh: 11: ./src/schemas/schema-test.sh: Bad substitution
56 info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
57 error Command failed with exit code 2.
61 ERROR: Job failed: command terminated with exit code 1

• CI 错误说 schema-test.Sh 文件的第 11 行有问题，但我没有看到问题。

• 它们在 MacOS 环境下运行良好，我的猜测是 CI 的 Docker 镜像是 Linux，导致了一些兼容性问题。

• 或者只是“/”符号不是转义码的问题？我很困惑。

感谢大家的帮助!

============================================= ===

• 按照@chepner的说法进行修改，但是测试还是有问题

23 $ yarn test:schema
24 yarn run v1.21.1
25 $ ./src/schemas/schema-test.sh

您的脚本不是使用 bash 执行的，所以不要使用 bash 特定的功能。假设您想将 foo.schema.json 更改为 foo.sample.json，您可以改用

SAMPLE_FILE=samples/${SCHEMA_FILE%.schema.json}.sample.json

这会从 SCHEMA_FILE 的扩展中删除 .schema.json，然后显式添加 .sample.json。
