Question

我有一个Angular 2应用程序运行正常，但在升级angular cli后，我无法使用ng serve提供我的应用程序。

我有以下错误：

ng serve                                  
Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "undefined".
Error: Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "undefined".

我按照Angular CLI migration guide中所示的所有步骤操作，这是：

sudo npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
sudo npm uninstall -g @angular/cli
npm cache clean
sudo npm install -g @angular/cli@latest
rm -rf node_modules dist
npm install --save-dev @angular/cli@latest
npm install

但是，正如我所说，我无法使用ng serve提供我的申请。

我不知道我可以在ng serve的项目中运行./node_modules/.bin/ng serve。谢谢Yakov。无论如何，我全局卸载了角度cli以避免冲突。

我仍然不能为我的项目服务，但我觉得我接近解决方案; - ）

我得到的错误与我在开头时发布的错误相同：

./node_modules/.bin/ng serve       
Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "undefined".
Error: Version of @angular/compiler-cli needs to be 2.3.1 or greater. Current version is "undefined".

¿任何线索？

错误消息告诉您＆＃34; @ angular / compiler-cli的版本需要为2.3.1或更高。＆＃34;看来package.json中的依赖项版本已经过时了。生成一个新项目并查看package.json中的依赖项，并根据需要更新您的项目。例如，这就是我在新生成的项目中所拥有的：

#include<iostream>
#include<vector>
using namespace std;
class Test{
public:
        static void func(){
                cout<<"Test::func()"<<endl;
        }
};

int main(){
        vector<void(*)()>list_of_methods;
        list_of_methods.push_back(Test::func);
        list_of_methods[0]();
        return 0;
}

升级angular cli后无法使用“ng serve”为我的应用程序提供服务
