I encountered the issue with the error   gyp ERR  configure error  gyp ERR  stack Error  Can t find Python executable  python   you can set the PYTHON env variable    Here is what I was doing and what finally worked   Disclaimer  I am just getting my hands into Node  Angular after many years in the Java  Linux world among others     Environment Description  Windows 8 1 64-bit  Cygwin  cygwin bash shell  Command used that led to error  npm install -g karma  Error   gyp ERR  configure error gyp ERR  stack Error  Can t find Python executable  python   you can set the PYT HON env variable   Discovery   which python  on bash shell clearly shows   usr bin python   Now that is annoying    Solution  This is only applicable to those using the environment similar to what I have  i e  using cygwin and bash shell  Hope it helps in other environments as well but keep in mind that your kettle of tea may look a little different than mine     Firstly  need to set the  PYTHON shell env variable in  bashrc using the explicit windows path to the python executable and not the unix like root path   usr bin  used by cygwin  Secondly  and this one took a lot of trial error and here s the gotcha  Cygwin installs python under  usr bin  which is really a mirror of  bin on windows  with the version  i e   in my system   usr bin python2 7 exe and then adds a link  usr bin python --  python2 7 exe  The problem is that gyp cannot follow this link and keeps giving the annoying error that it cannot find python even though you can find it just fine from the shell command line  With the above background now add the following line to your  bashrc   export PYTHON  C  cygwin64 bin python2 7 exe  or whatever is the version on your system     Now source your  bashrc from your home directory  on cygwin --   source  bashrc     You should be fine now and gyp will find the python executable   I hope this helps someone stumbling on the same or similar issue

The question is already answered but these were not working in my case which is alpine Linux based OS so maybe this helps someone else   I was also getting same error  gyp ERR  configure error  gyp ERR  stack Error  Can t find Python executable  python   you can set the PYTHON env variable    So fix by single line just add this if you are working in Dockerfile or install it in OS  apk add --no-cache python nodejs   in ubuntu  sudo apt-get install python3 6   Note  Node version 8

For Cygwin users   The python issue with using npm on an out-of-the-box Cygwin installation  is that node-gyp is giving a misleading error due to incomplete checking in the    npm node modules node-gyp lib configure js code   It s due to how Cygwin treats symbolic links  It doesn t do that properly in an out-of-the box installation  So the error messages from the above code become misleading  as it complains about the PYTHON path and not the existence of python exe  or link of  file itself   There are  at least  2 ways to resolve this     Installing the Cygwin package cygutils-extra and use winln  Use native Windows CMD in Admin mode      For  1  you can create a proper symlink from within Cygwin shell by doing these steps     To make the Cygwin environment treat Windows links properly     Alternatively add this to your   bashrc  for permanent use  export CYGWIN winsymlinks nativestrict    Install Cygwin package containing  winln  apt-cyg install cygutils-extra    Make a proper Windows sym-link  cd  cygdrive c cygwin64 bin  winln exe -s python2 7 exe python exe    Add PYTHON as a native Windows system wide variable  HKLM   setx  M PYTHON  C  cygwin64 bin python     Also assuming you are running the Cygwin shell as Admin   Using apt-cyg is recommended and can be found in various forms on github     For  2  the resolution for out-of-the-box Cygwin users is this     Open a native Windows CMD in Administrator mode and  cd C  cygwin64 bin  mklink python exe python2 7 exe   The result should look like this   C  cygwin64 bin gt ls -al python  lrwxrwxrwx 1 xxx            xxx   13 Jun  2  2015 python - gt  python2 7 exe lrwxrwxrwx 1 Administrators xxx   13 Aug 24 17 28 python exe - gt  python2 7 exe lrwxrwxrwx 1 xxx            xxx   13 Jun  2  2015 python2 - gt  python2 7 exe -rwxr-xr-x 1 xxx            xxx 9235 Jun  2  2015 python2 7 exe

Make sure you have all the required software to run node-gyp    https   github com TooTallNate node-gyp   You can configure version of Visual Studio used by node-gyp via an environment variable so you can avoid having to set the --msvs version 2012 property every time you do an npm install   Examples     set GYP MSVS VERSION 2012 for Visual Studio 2012  set GYP MSVS VERSION 2013e  the  e  stands for FREE  express edition      For the full list see   - https   github com joyent node blob v0 10 29 tools gyp pylib gyp MSVSVersion py L209-294   This is still painful for Windows users of NodeJS as it assumes you have a copy of Visual Studio installed and many end users will never have this  So I m lobbying Joyent to the encourage them to include web sockets as part of CORE node and also to possible ship a GNU gcc compiler as part of NodeJS install so we can permanently fix this problem    Feel free to add your vote at    https   github com joyent node issues 8005 issuecomment-50545326
