How to solve 'libcurl' not found with Rails on Windows

Question

This is giving me a headache. I\'m continuing a Rails project that started on Linux and I keep getting this when I run Puma on Ruby Mine:

Error:[rake --tasks

I just had the same problem on Windows 7 x64 and answered about it here. (Similar to you, I tried a lot of things that I thought should work but didn't.)

What worked was:

• To take a libcurl.dll from one of the packages found here, https://curl.haxx.se/download.html#Win64, and put it on the PATH.

  (Link was updated, but originally pointed to version 7.40)

• I just put it under \ruby24\bin\
• Maybe for you it's C:\Ruby24-x64\bin

(Here are things I tried that didn't work:)

• Putting on the PATH: the cygcurl-4.dll obtained from the current Curl Download Wizard
• Renaming the above cygcurl-4.dll to libcurl.dlland putting it on the PATH
• Installing the msys2 package libcurl-devel 7.57.0-1
• Renaming the msys-curl-4.dll (from msys2 found at msys64\usr\bin) to libcurl.dll

I didn't try building curl / libcurl from the latest source because I already have the latest according to pacman -Ss libcurl:

msys/libcurl 7.57.0-1 (libraries) [installed]
Multi-protocol file transfer library (runtime)

msys/libcurl-devel 7.57.0-1 (development) [installed]
Libcurl headers and libraries
