如何设置量角器的路径？

Question

我在运行 protactor 时收到此错误消息

错误信息：

protractor : The term 'protractor' is not      
recognized as the name of a cmdlet, function,  
script file, or operable program. Check the    
spelling of the name, or if a path was         
included, verify that the path is correct and  
try again.

我不小心删除了我的 node_modules 文件夹，但后来又添加了它，我在运行量角器或 webdriver-manager 时遇到了这个错误

我在尝试执行此操作时遇到此错误

npm install -g protractor

Answer 1

运行这个命令：npm install -g protractor

Answer 2

你试过了吗？

1. 通过以下命令卸载量角器。

npm uninstall -g protractor

1. 从以下目录位置删除量角器文件夹（如果存在）。 C:\Users\145702\AppData\Roaming\npm\node_modules\

2. 如果存在，请从以下位置删除量角器 windows cmd 文件。 C:\Users\145702\AppData\Roaming\npm

3. 重新安装量角器。

npm install -g protractor

一个好的做法，不要全局安装量角器。请在项目级别安装并使用它。
