"vue-cli-service test:unit "运行成功；但是 npm 退出错误代码 1 ELIFECYCLE

Question

我正在尝试运行 npm run test:unit，真正的错误似乎是来自 npm debug.log 的 test:unit: Failed to exec test:unit script。然而脚本运行并且执行没有问题。

我对 NPM + Node 有点陌生，所以我正在为这种行为而苦苦挣扎。当我运行 npm run test:unit （ Package.json 中的 "test:unit": "vue-cli-service test:unit" ）我得到这个输出：

Test Suites: 1 passed, 1 total
Tests:       1 passed, 1 total
Snapshots:   1 file obsolete, 0 total
Time:        1.208s
Ran all test suites.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/max/.npm/_logs/2020-03-26T18_16_36_155Z-debug.log

预期结果 测试应该刚刚通过，我不应该看到 NPM/Node 崩溃。

运行 ./node_modules/.bin/vue-cli-service test:unit 我只得到测试和 Jest 输出。一切都按预期工作。那么我的设置出了什么问题？

已尝试解决

重新安装node_modules
更新了 npm
更新为node:stable
重新安装 nvm（节点版本管理器）并更新
尝试向 vue-cli-service 添加额外的调试标志

Answer 1

./node_modules/.bin/vue-cli-service test:unit -u 修复了这个问题。这是 jest --updatesnapshot 的 shorthand 命令。

Since we just updated our component to point to a different address, it's reasonable to expect changes in the snapshot for this component. Our snapshot test case is failing because the snapshot for our updated component no longer matches the snapshot artifact for this test case.

To resolve this, we will need to update our snapshot artifacts. You can run Jest with a flag that will tell it to re-generate snapshots... - From Snapshot Testing.

观察到关于快照的错误：

Snapshots: 1 file obsolete, 0 total

不确定为什么这会导致 NPM 错误，但 -u 清除了它，我再也没有看到它。
