编辑：当使用离子2时会发生这种情况.我知道它还不稳定,但我认为可能有一些修复,因为似乎其他人没有得到这个问题.编辑结束
出于某种原因,我在尝试构建我的离子应用程序时突然开始出现此错误,使用“ionic build android”,以及“ionic build ios”：
An Error occurred trying to fall back to Cordova-lib execution: TypeError: Cannot read property 'then' of undefined

我迷失在这里,不知道从哪里开始寻找.
有没有人以前见过这个,能指出我正确的方向吗？
解决方法
@mabs @mgcdanny
我很确定我已经找到问题的根本原因.我跑了cordova -v并看到了这个输出 –
Ross-MBP:test rossmartin$cordova -v
/usr/local/lib/node_modules/cordova/node_modules/update-notifier/node_modules/configstore/index.js:53
throw err;
^
Error: EACCES: permission denied,open '/Users/rossmartin/.config/configstore/update-notifier-cordova.json'
You don't have access to this file.
然后我跑了
Ross-MBP:test rossmartin$sudo chown -R rossmartin ~/.config Ross-MBP:test rossmartin$cordova -v 6.0.0
现在我看到cordova报告它在6.0.0并且可以再次进行离子构建/准备.
我认为发生的事情是Ionic CLI认为没有安装cordova CLI.也许有可能在某个地方Ionic CLI执行了cordova -v并且被读取〜/ .config / configstore / update-notifier-cordova.json文件的权限问题挂起了.
