First, check out this link to find the solution if your system is Mac OS X.
If ur problem is still unsolved, or u r using the Windows OS, try the following step.
1. Check out your python version by running "py -V" in CMD;
2. Make sure you have download the corresponding egg file from this link. For example, if you have installed the python version 3.4.x in ur system, please download the egg file which is compatible with python 3.4. For instance, frida-3.0.1-py3.4-win32.egg (md5) this egg file requires the python 3.4.x with the 32-bits Windows OS.
3. Use 'cd' to go to your directory which holds the python installation file(either in the C:\Python.. directory or C:\Users\<your username>\AppData\Local\Programs\Python...);
4.Under the python directory, you will see an directory called "Scripts". "cd" into this directory and you should see a file named "easy_install.exe". Type the command in CMD terminal "easy_install.exe " and drag the egg file you have downloaded to the terminal. Then the command should looks like this "easy_install.exe ......egg". Type enter to run. Then it should works fine. After successfully installed the frida, you can see all the frida files are in the "Scripts" directory. If you don't want to "cd" into this directory to run corresponding exe file every time, remember to add the file path of the "Scripts" to the environment "PATH".
