Failed error not found python2

Below is the error that I get, when I try to generate a new project with JHipster:

gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2
gyp verb check python checking for Python executable "python" in the PATH
gyp verb `which` succeeded python C:Program FilesPython36python.EXE
gyp verb check python version `C:Program FilesPython36python.EXE -c "import platform; print(platform.python_version());"` returned: "3.6.4rn"
gyp verb could not find "C:Program FilesPython36python.EXE". checking python launcher
gyp verb could not find "C:Program FilesPython36python.EXE". guessing location
gyp verb ensuring that file exists: C:Python27python.exe
gyp ERR! configure error
gyp ERR! stack Error: Can't find Python executable "C:Program FilesPython36python.EXE", you can set the PYTHON env variable.

The rest is the stacktrace. The weird thing is I do have python installed and the environment variable is also set. My python version is «Python 3.6.4». Should I run it in Python 2? Is that the case?

Yes node-gyp requires Python 2.7, so you could try the answers to this question.

Alternatively, if you encounter this problem, it is probably due to node-sass and if you did not select Sass in JHipster options, you don’t need it but still you get it because it’s a transitive dependency from Angular, you can skip it by setting environment variables:

set SKIP_SASS_BINARY_DOWNLOAD_FOR_CI=true
set SKIP_NODE_SASS_TESTS=true

Another alternative is to use JHipster devbox.

There is another workaround to this error:

Delete your node_modules folder.
Run npm install --global windows-build-tools --save in your command prompt.
Install node-sass using the command: npm install node-sass@4.12.0 --save (or the latest version)

This should solve the error and return you a gyp info ok message!

If you encounter Node Sass could not find a binding for your current environment, resolve it by running:

npm rebuild node-sass

Just a note for anyone using React and facing the same error on Linux (Ubuntu):

Step 1: Install python 2.7

something similar to this

 sudo apt update
 sudo apt install python2-minimal

Step 2: Install make or just build-essential

something like:
```
sudo apt-get install build-essential
```

Then you can proceed with your previous activity…

I had to change to older node version:

PS C:> nvm list

    17.6.0
  * 16.13.2 (Currently using 64-bit executable)
    15.0.0
    10.19.0
PS C:> nvm use 10.19.0
Now using node v10.19.0 (64-bit)

Otherwise package node-sass failed to install. I did not investigate further why.

Before I write all, I’d like to say that before the update everything worked well; while updating node from version 7.2.1 to version 9.4.0 and npm from version 5.5.1 to version 5.6.0 in Windows 7 (64-bit) using the installer (https://nodejs.org/en/download/) and installing globally gulp-cli version 2.0.0, as far as npm install starts from the JointsWP folder I get the following error:

$ npm install

So I found out that the gulp-sass: ^2.0.1 installation installs node-sass@3.13.1 as well, but I’m frightened that node-sass@3.13.1 is not supported by node 8 and further versions. So I tried to indicate gulp-sass: ^3.0.0 in the package.json file and run npm install again as follows:

$ npm install

The solution for online search is:

npm install --global windows-build-tools --save

But it got stuck when installing windows build tools, so the solution is as follows

1, run npm install -g windows-build-tools
2, in the %temp% folder, find the latest file with a filename similar to dd_installer_20210421124746.log
3, check this file, make sure the log output Closing the installer with exit code 0
4, make sure you have vscode installed
PS: In fact, you can skip steps 2-4, because your python environment has already been installed, and the repeated steps of the installer have already been executed.
5, create a file named dd_client_.log in the %temp% directory
6, edit the file created in 5, add a line Closing installer. return code: 3010. and save it.
Note: Paste %temp% directly in Explorer to open your Windows temp directory.

Finally, NPM install is installed successfully

Download online, if the wrong version is the same as mine, you can use the files I downloaded. Click to download

After downloading, register it as a global environment variable in two ways:

First: Right-click my computer directly — «Attributes» — — «Advanced System Settings» — — «Environmental Variables» — — Add

The second is: set XXX = file path — «set SASS_BINARY_PATH = F: ww tools node-sass win32-x64-46_binding.

Check if the environment is appropriate: echo%SASS_BINARY_PATH%

If you print out the file address you have configured, it will be ok ay.
