运行 "npm run build" 后收到 npm 错误：npm 错误！代码 电子生命周期 npm 错误！错误 2

Question

在npm运行构建脚本执行后，我很难弄清我收到的这个npm错误的根源。终端中的错误如下：

npm ERR! code ELIFECYCLE
npm ERR! errno 2
npm ERR! vincent-site@1.0.0 build: `webpack --mode production`
npm ERR! Exit status 2
npm ERR!
npm ERR! Failed at the vincent-site@1.0.0 build script.
npm ERR! This is probably not a problem with npm. 
There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/vincentcastelli/.npm/_logs/2018-11-10T20_27_41_388Z-debug.

不太具有描述性。在写这篇文章时，我使用的是最新的npm版本(6.4.1)和最新的节点(11.1.0)。我还使用Babel 7和Webpack 4进行编译。到目前为止，我已经尝试了一些东西。

在使用最新版本的npm/node和旧版本时，我尝试了以下步骤：

1. npm缓存清理--强制
2. 通过$rm-rf node_modules文件夹删除node_module
3. npm安装

仍在接收错误。

我觉得这个问题源于包版本控制不兼容，但隔离这个问题一直很有挑战性。提前感谢您的帮助！

Answer 1

步骤1:$npm缓存清理--强制

步骤2：删除node_modules文件夹

步骤3：删除package-lock.json文件

步骤4:npm安装

要重新开始，$npm运行启动或npm运行构建

这对我有用。希望对你有用。

Answer 2

我发现我在Semaphore上的CI/CD管道在没有足够内存的虚拟机上运行，因此它失败了，并向我抛出错误

无论你在哪里运行命令，都要检查你的内存
