bcrypt not installing on ubuntu

Question

I tried to install bcrypt in Ubuntu but got following error. I can't understand error message properly. Here is some discussion regarding to the same problem : https://github.com/ncb000gt/node.bcrypt.js/issues/90 but still no solution found.

I have also tried to update npm(npm install -g npm) and installing the bcrypt with no luck.

Answer 1

You might want to try installing bcrypt with a more stable version of node.js . It might be also possible that you are missing some libraries that bcrypt requires, see https://stackoverflow.com/a/20895568/732396

Answer 2

Use the latest stable version of node.js. bcrypt hasn't been ported to node 0.11.x.

If you are using a git clone, simply cd into the tree and checkout 0.10.26-release:

git checkout v0.10.26-release
fetch

Then configure, make, and install as usual. Then try installing bcrypt again:

npm install -g bcrypt

Credit goes to yanhan. He pointed me in the right direction. I just wanted to post the specific commands that would fix it.

Answer 3

i have same problem but i fixed it

i used instead of npm yarn

yarn is package manager like npm

first install yarn your system then use this command to install bcrypt

yarn add bcrypt

Answer 4

TO install bcrypt on ubuntu current version bcrypt required to install-> node-pre-gyp

after install installing required

try cmd->sudo npm install bcrypt

Answer 5

Change you node version from 0.11.x to 0.10.x as bcrypt is not ported into 0.11.x.

if you have n (node version manager) installed then run:

n 0.10.x
(e.g x=26 or x=24 etc.)

Then run:

npm install bcrypt

inside your project directory. To install n run

npm install n

Answer 6

I've had a similar problem. Nothing worked, but what managed to do the trick was installing bcryptjs instead of bcrypt.
