（Ionic 2）尝试回退到Cordova-lib执行时发生错误：TypeError：无法读取未定义的属性'then' [英] (Ionic 2) An Error occurred trying to fall back to Cordova-lib execution: TypeError: Cannot read property 'then' of undefined

问题描述

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，因为看起来其他人没有得到这个问题。 编辑结束

This is happening when working with ionic 2. I know it's not stable yet, but i assume that there may be some fix for this, since it seems like others don't get this problem. Edit end

出于某种原因，我在使用ionic build android尝试构建我的离子应用时突然开始出现此错误，以及ionic build ios：

For some reason i've suddenly started to get this error when trying to build my ionic app, using "ionic build android", and also "ionic build ios":

我在这里迷路了，不知道从哪里开始寻找。

I'm lost here, and have no idea where to start looking.

以前是否有人见过这个，并且可以指出我正确的方向？

Is there anyone who has seen this before, and can point me in the right direction?

我很确定我已找出问题的根本原因。我跑了 cordova -v 并看到了这个输出 -

I am pretty certain I've figured out the root cause to the issue. I ran cordova -v and saw this output -

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报告它是6.0.0并且可以再次进行离子构建/准备。

Now I see cordova reporting it is at 6.0.0 and can do ionic build/prepare again.

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 cordova -v 并且因为读取〜/ .config / configstore的权限问题而被挂起/update-notifier-cordova.json file。

I think what happened is that the Ionic CLI did not think that the cordova CLI was installed. Maybe it is possible that somewhere the Ionic CLI does a cordova -v and was getting hung up by the permission issue reading the ~/.config/configstore/update-notifier-cordova.json file.
