默认节点包版本集无法构建，但修改后的版本集无效

Question

GitHub Issue
这个问题与更新版本的ts-loader抛出错误有关，当你从版本＆＃34; ^ 4.0.1＆＃34;降级tsloader时都会解决这个问题。到＆＃34; ^ 3.5.0＆＃34;

我使用backpack + typescript编写测试项目并使用以下命令安装节点包：

npm install -D jshint ts-loader typescript backpack-core copy-webpack-plugin nodemon  
npm install -S asciify  

经过一些修改后，会产生以下package.json：

{
  "name": "myTestProject",
  "version": "0.0.1",
  "description": "learn",
  "private": true,
  "scripts": {
    "start": "node ./prd/main.js",
    "dev": "backpack dev",  
    "build": "backpack build"
  },
  "license": "MIT",
  "devDependencies": {
    "backpack-core": "^0.7.0",
    "copy-webpack-plugin": "^4.5.1",
    "jshint": "^2.9.5",
    "nodemon": "^1.17.2",
    "ts-loader": "^4.0.1",
    "typescript": "^2.7.2"
  },
  "dependencies": {
    "asciify": "^1.3.5"
  }
}

但在使用npm run build im构建时收到错误：

> myTestProject@0.0.1 build /home/myUser/myProjectFolder/myTestProject
> backpack build

 ERROR  Failed to compile with 1 errors00:34:00

要解决此问题，我需要重新安装删除node_modules文件夹并替换package.json：

{
  "name": "myTestProject",
  "version": "0.0.1",
  "description": "learn",
  "private": true,
  "scripts": {
    "start": "node ./prd/main.js",
    "dev": "backpack dev",
    "build": "backpack build"
  },
  "license": "MIT",
  "devDependencies": {
    "backpack-core": "^0.5.0",
    "copy-webpack-plugin": "^4.5.0",
    "jshint": "^2.9.5",
    "ts-loader": "^3.5.0",
    "typescript": "^2.7.2"
  },
  "dependencies": {
    "@types/asciify": "^1.3.29",
    "asciify": "^1.3.5"
  }
}

添加了包nodemon以尝试解决但没有效果。 我的问题是我在经过大量工作后发现了这套工作包的版本，但它可以在另一个场景中发生，我将没有那么多时间来修复，甚至可以完全理解这里发生的事情。
npm list输出了几个问题。 任何人都可以解释为什么会发生这种情况，如果有某种方法可以避免这种类型的问题，我无法猜测每次输入npm install命令时都要使用每个包的工作版本。

ts-loader 4.0符合webpack突破性更改的重大变化。我怀疑你是在碰撞那个。我建议您使用3.5作为工作流程。
