@angular/compiler-cli@5.2.0 需要 typescript@'>=2.4.2 <2.6.0' 但找到的是 2.6.2

Question

对于已经创建的 Angular 项目，如何解决这个问题？我想用 2.6.2 Typescript

@angular/compiler-cli@5.2.0 requires typescript@'>=2.4.2 <2.6.0' but 2.6.2 was found instead.
Using this version can result in undefined behaviour and difficult to debug problems.
Please run the following command to install a compatible version of TypeScript.
    npm install typescript@'>=2.4.2 <2.6.0'
To disable this warning run "ng set warnings.typescriptMismatch=false".
The "@angular/compiler-cli" package was not properly installed. Error: Error: Cannot find module '@angular/compiler-cli'*

问题很明确...您的 Angular CLI 版本需要 Typescript 较低版本。

您需要降级您的 Typescript 版本。

在您的 package.json 更改中：

"typescript": "^2.6.2",

与

"typescript": "^2.4.2",

然后运行

npm install
