The term 'Enable-Migrations' is not recognized mvc code first

问题

I'm trying to run for the first time in my new mvc 4 application PM> Enable-Migrations –EnableAutomaticMigrations

I'm geting:

Enable-Migrations : The term 'Enable-Migrations' 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.
At line:1 char:1
+ Enable-Migrations –EnableAutomaticMigrations

What am I missing? I have installed e.f 5.

回答1:

Try typing in Package Manager Console:

Install-Package EntityFramework -IncludePrerelease

and then Restart Visual Studio.

回答2:

First "Install-Package EntityFramework -IncludePrerelease" and then Restarting Visual Studio as a Administrator worked for me together.

[Refer this] : Package Manager Console Enable-Migrations CommandNotFoundException only in a specific VS project

回答3:

I had the framework installed (5.x) and retried running the same commands after running in admin mode. This has resolved the issue -- quite strange though.

You have to make sure that you don't have any square brackets "[" in your path directory of the project. Apparently VS 2013 is not happy with project folders named with square brackets.
