Ionic 3：以“prod”模式构建：找不到模块“。” [英] Ionic 3: Build in “prod” mode: Cannot find module “.”

问题描述

我们有一个很大的 Ionic 应用，我们试图在生产中 build 模式，因为它几乎准备好了。我们发现的第一个问题是我们在编译时遇到 JavaScript 堆内存不足错误，但是我们通过给节点提供更多内存来修复它：

we have a large Ionic app that we’re trying to build in production mode since it’s almost ready. The first issue we found is that we were getting a "JavaScript heap out of memory" error when compiling, but we fixed it by giving more memory to node:

"ionic:build": "node --max-old-space-size=16384 ./node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build",

npm run ionic:build -- --prod

使用此命令，应用程序成功构建，但如果我打开它，我会收到以下错误：

With this command the app successfully builds, but if I open it I get the following error:

Uncaught Error: Cannot find module "."
at vendor.js:1
at vendor.js:1
at Object. (vendor.js:1)
at e (vendor.js:1)
at Object. (main.js:1)
at e (vendor.js:1)
at window.webpackJsonp (vendor.js:1)
at main.js:1

我搜索了一下，发现它可能是由 require ，但我们没有使用它。知道可能发生的事情或我们可以做些什么来调试问题？有没有办法在不缩小JS的情况下使用--prod？

I searched a bit and I found that it could be caused by require, but we aren’t using it. Any idea of what could be going on or what we can do to debug the issue? Is there any way to use "–-prod" without minifying the JS?

这是我的环境：

推荐答案

我发现了问题。在我的package.json中我使用：

I found the problem. In my package.json I was using:

"typescript": "^2.9.1",

将版本减少到 ~2.6.2 为我修复了它。

Decreasing the version to ~2.6.2 fixed it for me.
