Finally, I found the answer! for the above error, first of all, you should download and install Node.js 10.13 LTS on your system. Then in the command prompt, the bellow codes must be written :

>>npm cache verify 
>>npm config rm proxy
>>npm config rm https-proxy
>>npm config set registry
>>npm config set http://registry.npmjs.org
