xcode“无法打开文件”

xcode "The file couldn't be opened"

提问by Harry

I am using ionicto develop an app and everything had been working fine for some time.

我正在ionic开发一个应用程序，并且一切都运行良好有一段时间了。

However, I have recently updated to xcode 7.x so that I can compile for iOS 9. Now, when I run ionic prepare iosto generate the ios platform files and click on the *.xcodeprojfile, I get the following error:

但是，我最近更新到了 xcode 7.x，以便可以针对 iOS 9 进行编译。现在，当我运行ionic prepare ios生成 ios 平台文件并单击该*.xcodeproj文件时，出现以下错误：

The file couldn't be opened.

The file can open just fine in xcode 6.x

该文件可以在 xcode 6.x 中正常打开

I need it to work in xcode 7.x for the app to build with later SDK versions

我需要它在 xcode 7.x 中工作才能使用更高版本的 SDK 构建应用程序

Side note: I have searched for answers to this issue but in other cases the error message is more descriptive. The error message I get does not give a reasonwhy it cannot be opened, be it permissions or parsing issues or otherwise, so I am stumped as to how to fix this. I have tried deleting (null) lines in files and deleting my <user>.xcuserdatadfiles as suggested in these answers anyway to no avail.

旁注：我已经搜索了此问题的答案，但在其他情况下，错误消息更具描述性。我收到的错误消息没有给出无法打开的原因，无论是权限还是解析问题或其他问题，所以我对如何解决这个问题感到困惑。我已经尝试删除文件中的（空）行并<user>.xcuserdatad按照这些答案中的建议删除我的文件，但无济于事。

I have reinstalled El Capitan, xcode 7.2 and the necessary libraries (ionic, gulp, ..) and everything works fine now.

我已经重新安装了 El Capitan、xcode 7.2 和必要的库（ionic、gulp、..），现在一切正常。

I had something similar after updating Xcode, the git command line tool won't work after updating, turns out I had to open the Xcode and accept the license for new Xcode after that everything worked fine.

更新 Xcode 后我有类似的东西，更新后 git 命令行工具将无法工作，结果我必须打开 Xcode 并接受新 Xcode 的许可证，之后一切正常。

I had the same problem, and it was caused by a different format of Xcode project file. If the project is compiled with the old Xcode, the new one cannot not open it.

我有同样的问题，它是由不同格式的 Xcode 项目文件引起的。如果项目是用旧的Xcode编译的，新的就打不开。

I suggest you to remove any build file to make sure that next time project is really compiled, and if problem persist, remove also the old version of Xcode, because it looks like it is the one used to compile the project.

我建议您删除任何构建文件以确保下次项目真正编译，如果问题仍然存在，请删除旧版本的Xcode，因为它看起来是用于编译项目的版本。

Alternatively, maybe ionic CLI has some option to select which Xcode it should use.

或者，也许 ionic CLI 有一些选项来选择它应该使用的 Xcode。

2 possible solutions:

2种可能的解决方案：

1. Ionic configuration value

1. 离子配置值

It seems that somewhere in your project, a config value makes ionic still thinkyou use XCode 6 because you were using it before, and so continues to generate the project file accordingly.
What happens if you start over, in another directory, from a starter project file:

似乎在您的项目中的某个地方，配置值使 ionic 仍然认为您使用 XCode 6，因为您之前使用过它，因此继续相应地生成项目文件。
如果您在另一个目录中从初始项目文件重新开始，会发生什么情况：

ionic start myApp tabs
ionic prepare ios

Can you open the generated XCode project file? If yes, I suggest you to copy over this starter project all the files from your original project.

你能打开生成的 XCode 项目文件吗？如果是，我建议您将原始项目中的所有文件复制到此启动项目上。

2. Update nodeJs to the latest version

2.更新nodeJs到最新版本

I see you use node 4.x.x, try updating to 5.x.x.

我看到你使用节点 4.xx，尝试更新到 5.xx
