Error installing bcrypt with npm

I'm unable to install bcrypt using npm on my machine because I encounter the following errors. I have been troubleshooting the issue without much luck. Can you recommend any steps to diagnose or fix the problem so I can run npm install bcrypt successfully?

回答1:

The easy solution is just switch from the "bcrypt" npm module to bycryptjs or bcrypt-nodejs. It's the exact same API, but pure JS so no native add-ons to deal with.

npm install --save bcryptjs && npm uninstall --save bcrypt

Then change your require calls to "bcryptjs", but all your code otherwise can be unchanged.

Long term, I suspect at the moment bcrypt may not be ready for node v0.12.0 yet, but if not it will eventually be updated and ready.

回答2:

for windows install the following module

npm install -g node-gyp
npm install --g --production windows-build-tools

then try to install

npm install bcrypt

回答3:

On this command:

npm install --g --production windows-build-tools

You may have to run this in Powershell as administrator on your Windows machine.

You do that by right-clicking on Powershell and select "Run As Administrator"

回答4:

On Mac OS, after a Xcode update, running sudo gcc and accepting Xcode's new license solved the problem!

回答5:

I just ran the following then tried the install and it worked:

npm install node-pre-gyp -g

回答6:

Had the same problem. Updating npm and try again (npm install -g npm usually). It fix the issue for me.
