Question

我克隆了Angular quickstart。然后我运行npm install，然后npm start。这就是我得到的。

$ npm start

> angular-quickstart@1.0.0 prestart /home/ecarroll/code/angular/quickstart
> npm run build


> angular-quickstart@1.0.0 build /home/ecarroll/code/angular/quickstart
> tsc -p src/


> angular-quickstart@1.0.0 start /home/ecarroll/code/angular/quickstart
> concurrently "npm run build:watch" "npm run serve"

版本，

node --version
v8.4.0

npm --version
5.4.0

tsc --version
Version 2.5.2

如果我尝试手动执行lite-server，那么它也会失败

node ./node_modules/lite-server/bin/lite-server -c bs-config.json

简单易用的最佳解决方案

更新npm，以便不再发生问题sudo npm update -g npm
从角项目的目录中运行它。
```
find ./node_modules/ -type f -name xdg-open -exec chmod a+x {} \;
```
这会xdg-open +x允许npm start打开浏览器到应用程序网址而不会抛出异常。

禁用打开浏览器

根据Tyler Christian的评论中提出的建议，与this answer类似，有一个名为bs-config.json的文件

从中更改

{
  "server": {
    "baseDir": "src",
    "routes": {
      "/node_modules": "node_modules"
    }
  }
}

通过向此添加open参数，

{
  "open": false,
  "server": {
    "baseDir": "src",
    "routes": {
      "/node_modules": "node_modules"
    }
  }
}

我现在将研究为什么会产生这种神秘错误，以及潜在的问题是什么。

而且，这是问题所在 - 它位于包opn中。谢谢你向我解释this error prone process works on March 14, 2017.埃文卡罗尔是如何发挥作用的。
