Windows VM无法在TravisCI上启动

Question

我看到旋转的圆圈超过一个小时（“启动虚拟机”）：

这是我的.travis.yml文件：

language: minimal

git:
  depth: 1

jobs:
  include:


   - script: ./scripts/travis/run.sh 8
     name: nodejs_8_windows
     os: windows
     env:
       - foo=bar11


   - script: ./scripts/travis/run.sh 9
     name: nodejs_9_windows
     os: windows
     env:
       - foo=bar12


   - script: ./scripts/travis/run.sh 10
     name: nodejs_10_windows
     os: windows
     env:
       - foo=bar13


   - script: ./scripts/travis/run.sh 11
     name: nodejs_11_windows
     os: windows
     env:
       - foo=bar14


   - script: ./scripts/travis/run.sh 12
     name: nodejs_12_windows
     os: windows
     env:
       - foo=bar15

有人知道为什么Windows VM无法启动吗？是我的配置吗？
