请将您的Cordova CLI安装到版本＆gt; = 4.2.0 npm install -g cordova
在Ubuntu中打开终端（ Ctrl + Alt + T ）
检查您的Cordova CLI版本
如果＆lt; 4.2.0
做sudo npm install -g cordova
移至离子项目文件夹
cd <your project root folder>
然后做
sudo npm install
sudo npm update
确保一切都是最新的。
然后告诉我错误是否仍然存在。

仔细观察，我发现在cordova + ionic安装过程中出现了错误。 然后我发现了一个提示 - 问题可能是旧的npm版本。
所以我跑了：
npm -g install npm
和...问题解决了!!
答案 3 :(得分：0)
我得到了同样的错误。我所做的只是
ionic start myapp --v2
在完成错误后，我转到
cd myapp
并运行
npm install
然后它工作正常
