Hi all Iam new to linux with elementary knowledge.I have following problem.
Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
how can I solve it?

...and since you don't provide any useful details, no one can help you. You need to tell us what version/distro of Linux you're using, where you're getting these messages, what software you're using, etc.

Giving a generic set of suggestions that some piece of software gave you doesn't give anyone much to go on.

CPU speed governor is an option not a module.

Likely you will need to be root, or use sudo in order to implement new CPU speed settings.

The only way to know if the policy is invalid is if you look at the CPU speed information in the list of available frequencies file.

The fact that it is complaining about no userspace governor, means that you do need to be root or use sudo.

More information is needed to assist you in solving this.

What version of Linux are you running?
What CPU are you running it on?
What commands have you tried, and have you tried it as superuser?
