Question

我希望将TypeScript更新为最新版本

首先我在全球范围内做了，然后我在本地尝试了，即

D:\dev\myapp>npm install - typescript@latest 
D:\dev\myapp>npm install  typescript@latest --savedev

我有2个类似的项目（Ionic 2）

第一个（几乎空白的测试项目）工作正常，但第二个我收到以下错误..

 myapp@ D:\dev\myapp 
    `-- typescript@2.1.5  invalid

我查看了package.json，它没有更新（仍然是2.0.9）

我已经尝试了几次，但一直都失败了。我不知道如何追踪它。

有没有人有任何想法？

提前致谢！

[UDPATE] 思想会增加我得到的额外警告

尝试更新npm，然后再试一次，可以做到这一点。
