尝试升级 TypeScript 时出错

Question

我想将我的 TypeScript 更新到最新版本

首先我在全球范围内做了，然后我在本地尝试了，即

D:devmyapp>npm install - typescript@latest 
D:devmyapp>npm install  typescript@latest --savedev

我有 2 个类似的项目（离子 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:devmyapp 
    `-- typescript@2.1.5  invalid

我在package.json中查找，它没有更新（仍然是2.0.9）

我已经尝试了几次，但一直失败。我不知道如何追踪这一点。

有人有什么想法吗？

提前感谢！

尝试更新 npm，然后重试，可以解决问题。
