Cordova构建和运行面临错误变量.forEach不是一个函数

Question

我的离子项目突然没有响应任何Cordova构建/运行命令。

Macbooks-MBP:upost Kira$ cordova run ios
Error: variables.forEach is not a function
Macbooks-MBP:upost Kira$ cordova run android
Error: variables.forEach is not a function
Macbooks-MBP:upost Kira$ cordova build ios
Error: variables.forEach is not a function
Macbooks-MBP:upost Kira$ cordova build android
Error: variables.forEach is not a function
Macbooks-MBP:upost Kira$

这是Cordova -d build ios回复

Macbooks-MBP:upost Kira$ cordova -d build ios

我尝试过的步骤：

1. 克隆另一个新项目
2. 重新安装所有节点，npm，Cordova，ionic
3. 尝试示例项目，它可以正常工作
4. 从其他人复制项目，也没有工作
5. 删除/添加适用于iOS和Android的Cordova平台

组件版本：

1. Cordova v7.0.1
2. ionic v3.5.0
3. node v6.11.1
4. npm v3.10.10

Answer 1

删除ios-sim

下的platforms/cordova/node_modules/

输入命令npm i -g install ios-sim@latest

以及npm i -g install ios-deploy@latest

然后Cordova build ios或Cordova run ios将起作用
