npm现在未安装量角器 [英] Protractor not installed now with npm

问题描述

我尝试使用 npm install -g量角器

全局安装量角器，这是错误消息，我在任何情况下都知道。
我以前在全球范围内安装了量角器，并且运行良好。

Here is the error message,I got it in every case. I installed globally the protractor before,and worked well.

我对此无能为力。
这个有什么想法吗。

I can not do anything to this. Is there any idea to this one.

推荐答案

下载并安装NPM时，请确保您具有最新版本。
打开命令提示符并键入。安装可能需要一段时间。

When you download and install NPM make sure you have the latest version. Open your command prompt and type this. This might take a while to install.

npm install npm @ latest -g

npm install npm@latest -g

或者尝试这个链接

使用此命令检查npm版本后

After checking your npm version with this command

npm --version

npm --version

键入此项以安装量角器

npm install -g量角器

npm install -g protractor

然后通过检查您拥有的版本来检查量角器是否成功安装

Then check if protractor was successfully installed by checking the version you have

量角器--version

protractor --version
