Error installing bcrypt with npm

Question

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

Answer 1

The accepted solution works but bcryptjs is slower than python and c++ version.

If you still want bcrypt insted of bcryptjs working solution are command below, but they can also have problem.

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

In Windows the second command will try to install visual studio along with python and hence the problem arises. because we why would we want to install Visual studio and it take a lot of time. and it also hinders the installation of python. And if you forget to run those command as Administrator then they will get installed at C:\Users\User.windows-build-tools which further will not work because node will search for python in C:\ or C:\Program Files\ . Hence this commands in some case increase your complications.

So the best idea for you is to ✔️install python manually for All Users And It is not necessary to add python to environment path. And run only the first command i.e

✔️ npm install -g node-gyp

Now you are ready to install bcrypt

npm install bcrypt

Answer 5

I was facing the same issue on the server side( aws ubuntu 16.04).

I tried deleting node_module/bcrypt by sudo rm -rf node_module/bcrypt multiple times and reinstalled it again and again by various ways but still facing the same issue.

I checked node version with nvm and it was also showing stable (v10.11.0).

Finally, I tried.

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

and it worked for me.
