A lot of issue were submitted on windows builds, you definitely should review them https://github.com/nfroidure/ttf2woff2/issues?q=is%3Aissue+is%3Aclosed

Thank you for putting me on the right track.
https://github.com/nodejs/node-gyp#installation showed me what to do.
npm install --global --production windows-build-tools
and re-installed npm install ttf2woff2 -g
everything's fine now.

Hi,

I'm trying to install Angular by running npm install -g @angular/cli

I have this error:-

C:\Users<MyUsername>\AppData\Roaming\npm\ng -> C:\Users<MyUsername>\AppData\Roaming\npm\node_modules@angular\cli\bin\ng

[email protected] install C:\Users\lancaril\AppData\Roaming\npm\node_modules@angular\cli\node_modules\node-sass
node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.7.2/win32-x64-59_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.7.2/win32-x64-59_binding.node":

tunneling socket could not be established, statusCode=407

Hint: If github.com is not accessible in your location
try setting a proxy via HTTP_PROXY, e.g.

  export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

  npm config set proxy http://example.com:8080

.
.
.
.
.

I have configured both proxy and https-proxy variables to my proxy yet the error persists.

Any ideas?

Thanks in advance

Sorry, this is the command I ran:

npm install -g @angular/cli

I have faced and fixed this issue relates node-sass and python error.Try installing latest angular cli command with the steps below

Set the system variable path as well:
C:\Users\windowsusername\AppData\Roaming\npm

C:\Users\windowsusername\AppData\Roaming\npm\node_modules@angular\cli\bin;

C:\Program Files\nodejs;

Then start using angular cli command prompt using:
angular client project folder path>npm install -g @angular/cli@latest

angular client project folder path>npm install -g node-gyp

npm config set python F:\Python\python.exe doesn't work even I surely have a Python 3.5 installed there. (As currently gyp really doesn't support Python version > 3.0.)

npm config set python "/usr/local/bin/python" fixed the problem for me on macOS Mojave.

I tried fixing it on Ubuntu / Linux, but now my yarn is taking really long so I probably broke something. Leaving this here for reference so I can look into it later, but DO NOT do this.

# do NOT run this
$ apt install python2.7
$ npm config set python /usr/bin/python2.7
