我在我的 bitbucket 管道中得到了这个：
pipelines:
branches:
develop:
- step:
caches:
- composer
name: unit tests - Delivery
image: totersapp/laravel-docker:phpredis
script:
- echo "memory_limit=512M" > /usr/local/etc/php/conf.d/memory-limit-php.ini
- ln -f -s .env.pipelines .env
- composer install
services:
- postgres
- redis
每次运行时都会下载相同的文件（即使是在第二次运行时）..有什么想法吗？
这是composer安装的日志：
+ composer install

更新：无法覆盖默认值
基于这个答案 https://stackoverflow.com/a/59542186/766570我试过这个：
- step:
caches:
- composer
image: totersapp/laravel-docker:phpredis
script:
- composer install
..
definitions:
caches:
composer: /composer/cache
我的问题是我试图用custom缓存目录（在本例中是/composer/cache）但话又说回来，我没有办法在提供自定义缓存目录作为选项时调用composer安装命令（即，这就是bitbucket教程在本例中对bundle所做的事情：
- bundle install --path vendor/bundle
换句话说，我不能运行这样的东西：
- composer install --cache-directory /composer/cache
更新2：composer.json和composer.lock之间的差异
- 首先作为健全性检查，我只是cloned https://bitbucket.org/toters/composer-cache/src/master/的回购协议尼科
哈斯 https://stackoverflow.com/users/1116230/nico-haase，并运行管道，passed https://bitbucket.org/toters/composer-cache/addon/pipelines/home#!/results/3 ✅
- 我复制并粘贴了他的内容bitbucket-pipelines.yml https://bitbucket.org/toters/composer-cache/src/master/bitbucket-pipelines.yml到我的，我复制并粘贴了他的作曲家.json https://bitbucket.org/toters/composer-cache/src/master/composer.json，我运行了管道。失败❌
但我在作曲家安装日志中得到了这个：
+ composer install --ignore-platform-reqs --no-scripts

Script cache:clear returned with error code 1
!! Fatal Error: composer.lock was created for PHP version 7.2.9 or higher but the current PHP version is 7.1.32.
注意：在我原来的composer.json文件中，我找到了这一行
"config": {
..
"cache-dir": "~/.cache/composer",
},
所以我删除了该行，但这也没有帮助。
仍在挖掘（作为记录，这是我的composer.json好像 https://bitbucket.org/snippets/toters/onrA6z，我保留了cache-dir部分内容供参考）
