警惕 Travis CI 的 npm 缓存
Post author: Claude Ray · 2019-08-01 · via Claude's Blog

从 2019 年 7 月份开始，Travis CI 默认开启 npm 缓存。这意味着 node_module 和 package-lock.json 会在初次构建时缓存，倘若后续更新 npm 依赖而不刷新该缓存，可能带来构建失败的问题。

下面是发现问题的源头。

在为一个项目添加了新的依赖 rimraf 之后，Travis CI 意外地报错：

1
sh: 1: rimraf: not found

此时 .travis.yml 配置为

sudo: false
language: node_js
node_js:
  - '8'
  - '10'
before_install:
  - npm i npminstall -g
install:
  - npminstall
script:
  - npm run ci
after_script:
  - npminstall codecov && codecov

很明显新增的 npm 依赖没有安装上，但本地测试没有问题，于是替换 npminstall 为原生的 npm install，降低问题排查范围。

node_js:

然而移除 npminstall 之后，报错变为

    at flatNameFromTree (/home/travis/.nvm/versions/node/v8.16.0/lib/node_modules/npm/lib/install/flatten-tree.js:39:14)

之后，去掉 rimraf 依赖于事无济，重跑其他 node 项目的 ci 却一切正常，因此最终确定是 travis 运行环境带来的问题。

果然，寻找刷新方法的过程中发现了右侧 More options 中的 Caches 选项，点击里面的删除键后，CI 重新运行成功。

Please note that as of July 2019, npm is cached by default on Travis CI

To disable npm caching, use:
