如何在Mac上运行命令'ionic cordova build ios'时修复“新的SubprocessError错误”

Question

我打算在Mac上构建ios平台，我遇到了这个问题。

我使用macOS 10.12，Xcode 8和Ionic 4.我尝试过"ionic cordova platform rm ios"和"ionic cordova platform add ios"并构建但它仍然无法正常工作。

Daos-Mac：Ionic_UI_V1 daovu $ ionic cordova build ios

ng run app：ionic-cordova-build --platform = ios

新的SubprocessError出错（/usr/local/lib/node_modules/ionic/node_modules/@ionic/utils-subprocess/dist/index.js:40:23）...

Answer 1

尝试： -

1）删除ios平台：

ionic cordova platform rm ios

2）添加ios平台：

ionic cordova platform add ios

3）准备ios平台（将源代码发送到ios平台）

ionic cordova prepare ios

4）运行构建和安装：

Open xcode - select profile - run application

Answer 2

我在使用Ionic v4 / XCode 10.2.1在Mac 10.14.5上安装Calendar Plugin时遇到了这个问题。

ionic cordova plugin add cordova-plugin-calendar
> cordova plugin add cordova-plugin-calendar
Error

at new SubprocessError
(/Users/brippe/.npm-packages/lib/node_modules/ionic/node_modules/@ionic/utils-subprocess/dist/index.js:40:23)
at ChildProcess.<anonymous>

我通过运行解决了它：

npm uninstall -g cordova

然后再次重新安装cordova

npm install -g cordova

终于成功安装了日历插件：

ionic cordova plugin add cordova-plugin-calendar
> cordova plugin add cordova-plugin-calendar

You have been opted out of telemetry. To change this, run: cordova telemetry on.
Adding cordova-plugin-calendar to package.json

我正在使用Capacitor，所以一旦我同步，我的构建过程仍在运行。

npx cap sync
