In my case, 3 steps solved this problem.

• set http_proxy=http://127.0.0.1:1080 set https_proxy=http://127.0.0.1:1080
• add 199.232.4.133 raw.githubusercontent.com to hosts files.
• cmd.exe ipconfig/flushdns

This seems to be related to #1758. I’m behind a corporate proxy, which seems block a process in the postinstallation script of gifsicle in which something is downloaded from GitHub. As a fallback gifsicle then compiles from source instead, throwing an error because it uses an executable that not exists on Windows.

I realize it’s not for docusaurus to fix, but maybe it could be an idea to review if this dependency is actually needed? Because as of now docusaurus can’t be installed by users behind corporate proxys, at least not by me.
