错误：这可能不是 npm 的问题。上面可能有额外的日志输出

Question

在我的项目中，我使用 Angular6 作为前端。现在我要做的是将远程服务器中的项目部署到实际服务器中。我首先使用npm run build -prod命令来构建前端。但是我无法构建我的项目，因为以下错误一次又一次发生，

npm ERR! code ELIFECYCLE
npm ERR! errno 134
npm ERR! Trackit-Revamp@6.0.0 build: `ng build --prod --build-optimizer --aot`
npm ERR! Exit status 134
npm ERR!
npm ERR! Failed at the Trackit-Revamp@6.0.0 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!     C:\Users\Indrajith.E\AppData\Roaming\npm-cache\_logs\2019-08-22T08_41_00_271Z-debug.log

我在C:\Users\Indrajith.E\AppData\Roaming\npm-cache\_logs\2019-08-22T08_41_00_271Z-debug.log文件路径中的错误日志包含与上述相同的错误详细信息。

我该如何解决这个问题？

Answer 1

Delete your package-lock.json file and node_modules folder. Then do npm cache clean

npm cache clean --force

do npm install

again and run

Answer 2

最后，我在不重新安装 npm 的情况下找到了解决此问题的方法，我将其发布，因为将来它会对某人有所帮助，大多数情况下都会发生此错误，因为 javascript 堆内存不足。正如错误本身所说，这不是 npm 的问题。我们唯一要做的就是

代替，

npm  run build -prod

通过以下方式扩展javascript内存，

node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build --prod

Answer 3

请删除package-lock.json并清除 npm 缓存并npm cache clear --force 删除整个node_modules目录

最后使用npm install/再次安装或更新软件包npm update 您还可以使用以下命令添加任何新软件包npm install <package-name>

这对我来说是固定的。

谢谢，编码愉快。

我在Ubuntu 18.04 上。我通过使用以下命令增加inotify max_user_watches解决了这个问题：

我刚刚尝试过：

sudo npm start

它奏效了。

我已经有同样的问题了。我使用npm update和npm cache clean --force修复它
