Steps to reproduce

问题复现

1. 使用vue create test-demo创建项目test-demo，自定义配置如下：
   
2. 进入test-demo目录，启动项目npm run serve，出现以下报错：
   

错误原因分析

• 仔细看报错提示Error: Cannot find module 'E:\@vue\cli-service\bin\vue-cli-service.js'
• 发现事实上在E盘下的确没有这个模块
• 这个模块正确的路径应该是在

E:\[项目文件]\node_models\.bin\@vue\cli-service\bin\vue-cli-service.js'

• 思考是不是在启动服务的时候，配置文件出错导致没有正确的找到模块路径
• 然后将node_modules/.bin/vue-cli-service.cmd文件的内容修改为：

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe"  "%~dp0\..\@vue\cli-service\bin\vue-cli-service.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node  "%~dp0\..\@vue\cli-service\bin\vue-cli-service.js" %*
)

• 项目可以正常运行了
• node_modules/.bin/vue-cli-service.cmd文件的原本内容：

@ECHO off
SETLOCAL
CALL :find_dp0

IF EXIST "%dp0%\node.exe" (
  SET "_prog=%dp0%\node.exe"
) ELSE (
  SET "_prog=node"
  SET PATHEXT=%PATHEXT:;.JS;=;%
)

"%_prog%"  "%dp0%\..\@vue\cli-service\bin\vue-cli-service.js" %*
ENDLOCAL
EXIT /b %errorlevel%
:find_dp0
SET dp0=%~dp0
EXIT /b

请问这个是什么原因导致的？有没有什么彻底的解决方法？

What is expected?

npm run serve可以正常启动项目，不会报错

What is actually happening?

npm run serve无法正常启动项目，报错Error: Cannot find module 'E:@VUE\cli-service\bin\vue-cli-service.js'

The error caused by the & of path E:\webpack&vuecli&vue-router&vuex

and node_modules/.bin/vue-cli-service.cmd is generated by npm

Is it because of the environment or configuration?How to deal with this situation?

@wanghuan19961020 I am not familiar with the syntax of .cmd. I can only suggest don't use & in your directory on windows 10. Maybe someone else can help you.
