should be a dependency that does not have a global installation 
 
  must reinstall the cross-env module 
 
  in fact, the entire file directory can be pulled over; you can try using the mobile hotspot USB to share to the computer network, and reinstall the package 
 
  how do you copy it? Did you copy the hidden files in the root directory? 
 
  node_modules multiple copies 
 
  it is recommended that the copy do not carry the node_modules file, and then directly re-open the instruction, npm i in the project cnd | | cnpm I and then start 
 
  I am now in the same situation 
 
  brothers, it is under the premise that there is no Internet connection, so do not consider npm installation. I have also encountered such a problem, I would like to ask whether the landlord problem has been solved (it is all disgusting of the company, banning the network, evil company) 
 
  I have also encountered your problem, copy to other computers can not run, there is no network, how to do.
