Sorry It's a long error but I hope someone helps me because I have to finish this project very quickly and I haven't started yet.

Answer 1

如果您使用的是 Windows，则需要通过以下方式使用 bcryptjs：

npm install --save bcryptjs

Answer 2

You are facing some of the error described inside the bcrypt package. I advice you to go to their npm page and read through the description.

They have a paragraph where they describe:

IF you have an error like this:

node-pre-gyp ERR! Tried to download(404): https://github.com/kelektiv/node.bcrypt.js/releases/download/v1.0.2/bcrypt_lib-v1.0.2-node-v48-linux-x64.tar.gz

make sure you have the appropriate dependencies installed and configured for your platform. You can find installation instructions for the dependencies for some common platforms in this page .

So I just advice you to go to their page and follow the instructions..
