How to fix?

Answer 1

There hemorrhagic with python. Try bcryptjs

Answer 2

Faced the same problem:
1. First I tried to follow the instructions for Windows 10 from here:
Instructions for Windows
Opened powershell as administrator and entered the command
I waited for the complete installation - you should see All done
But the error remained ...
2. Then I decided to completely remove node.js and installed the latest version at the moment.
Installed with all dependencies. This helped resolve the issue.
After that, bcrypt installed successfully in node_modules.
