TypeError：无法读取null的属性'config' [英] TypeError: Cannot read property 'config' of null

问题描述

将我的Angular项目从本地计算机复制到我的Linux服务器之后，我尝试使用 ng serve 运行该项目，但它无效。相反，它在控制台的编辑器中打开了一个新文件。

After copied my Angular project from my local computer to my Linux server, I tried to run the project using ng serve and it didn't work. Instead it opened a new file in an editor in the console.

然后我研究并提出了 npm start 。但是，那也行不通。给我以下错误。

Then I researched and came up with npm start. However, that also not working. Gives me the following error.

Cannot read property 'config' of null

我有 .angular-cli.json 文件也在那里。它并没有丢失。

And I have the .angular-cli.json file also there. It's not missing.

这可能是什么原因？任何解决方案。？

What could be the reason for this ? And any solution.?

推荐答案

试试这个

npm install - g @ angular / cli

npm install -g @angular/cli
