Why powershell does not run Angular commands?
提问by Amir Makram
I have started to learn Angular but I note that powershell in Windows gives me an error whenever I make an angular command like:
我已经开始学习 Angular，但我注意到每当我发出如下 angular 命令时，Windows 中的 powershell 都会给我一个错误：
ng new new-app
or
或者
ng serve
this is the error what I got:
这是我得到的错误：
ng : File C:\Users\< username >\AppData\Roaming\npm\ng.ps1 cannot be loaded because
running scripts is disabled on this system. For more information, see
about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

+ ng serve
+ ~~
+ CategoryInfo : SecurityError: (:) [], PSSecurityException

P.S. I try these commands in cmd and it works.
PS我在cmd中尝试这些命令并且它有效。

Remove ng.ps1from the directory C:\Users\%username%\AppData\Roaming\npm\then try clearing the npm cache at C:\Users\%username%\AppData\Roaming\npm-cache\
ng.ps1从目录中删除，C:\Users\%username%\AppData\Roaming\npm\然后尝试清除 npm 缓存C:\Users\%username%\AppData\Roaming\npm-cache\

script1.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170
无法加载 script1.ps1，因为在此系统上禁用了运行脚本。有关详细信息，请参阅http://go.microsoft.com/fwlink/?LinkID=135170 上的about_Execution_Policies
This error happens due to a security measure which won't let scripts be executed on your system without you having approved of it. You can do so by opening up a powershell with administrative rights (search for powershell in the main menu and select Run as administrator from the context menu) and entering:
发生此错误是由于一项安全措施，未经您批准，该措施不会让脚本在您的系统上执行。您可以通过打开具有管理权限的 powershell（在主菜单中搜索 powershell 并从上下文菜单中选择以管理员身份运行）并输入：
set-executionpolicy remotesigned
回答by Palla Vishal
open windows powershell, run as administrater and SetExecution policy as Unrestricted then it will work.
打开 windows powershell，以管理员身份运行，将 SetExecution 策略设为 Unrestricted，然后它就可以工作了。
