@rwdietrich your log includes the error that you're missing python:

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

@satishweb you might be short of a dependency too. I stumbled upon this list of required packages https://gist.github.com/rakam/b851c02589c3467982b0 which helped me resolve the problem on alpine

[rwdietrich]

@masone Thanks for the comment. I noticed python missing as well, but it seems like it should have been installed as a dependency. I tried "npm install python" but got the same results for bcrypt.

[masone]

Python is a system level dependency, not a missing npm package. https://www.python.org/downloads/

[rwdietrich]

Grumble, grumble. Still a dependency. Anyway, I installed 3.5 and then found I needed 2.7. Then tried pointing PYTHON env variable to the executable and got:

`c:\Build\nodejs\test>npm install bcrypt

[email protected] install c:\Build\nodejs\test\node_modules\bcrypt
node-gyp rebuild

c:\Build\nodejs\test\node_modules\bcrypt>if not defined npm_config_node_gyp (node "G:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin....\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "" rebuild )

MSBUILD : error MSB3428: Could not load the Visual C++ component "VCBuild.exe". To fix this, 1) install the .NET Framework 2.0 SDK, 2) install Microsoft Visual

So I guess I need to find the VC++ components now. All this is a painful departure from trying to get the original task done.

[jamesarmenta]

Same issue as OP here. I've searched around and this seems to be a common occurrence for windows users, but I am on a mac.

[rwdietrich]

Guess I don't understand why an issue that hasn't been resolved is closed with no comments. Does the closer simply want to avoid fixing an issue on Windows?

[jonatanblue]

Judging by the comment above by @masone and the fact that the project readme states a dependency on Python 2.x, I believe the solution is to ensure Python is installed on the system.

Installing Python before installing bcrypt resolved this issue for me when installing in a container based on the debian:jesse Dockerimage:

sudo apt-get update && sudo apt-get install -y build-essential python

[rwdietrich]

@jonatanblue, I appreciate your willingness to comment, but read a bit more closely. Python 2.7 was installed, and more importantly, it was a problem on Windoze. Your example uses sudo and apt-get, not available in that environment.
