Could you check whether these help?

yeah，I have tried almost every methods，including luarocks、MSYS2 and so on, however, every method has its own problem that I can not solove

Could you go into the directory luasnip is in and run make install_jsregexp manually, and post the whole output? Unfortunately I don't have a windows setup currently, so I can't test this stuff myself :/

The meaning of Chinese in the output is that system cannot find the files

Hey, as this is probably the issue someone finds when googling it. I also had the same problems and solved it with the help of https://github.com/L3MON4D3/LuaSnip/issues/986#issuecomment-2060360732

Also to to make it more convinient I build a powershell script I can run. What is needed:

• Powershell (7) (winget install --id Microsoft.Powershell)
• msys2 (https://www.msys2.org/ - https://github.com/msys2/msys2-installer/releases)
• Run this 3 commands in the msys2 UCRT console:

  pacman --noconfirm -Syu
  pacman --noconfirm -S git
  pacman --noconfirm -S mingw-w64-ucrt-x86_64-luajit mingw-w64-ucrt-x86_64-make mingw-w64-ucrt-x86_64-gcc

Than I added in my nvim dir ( c:/users/MYUSERNAME/appdata/local/nvim/luasnip_jsregexp_build.ps1) this powerhell script:

$find = '$(CC) $(LDFLAGS) $^ $(LDLIBS) -o $@'
$replace = '$(CC) $^ $(LDLIBS) -o $@ $(LDFLAGS)'

$file = '.\deps\jsregexp\Makefile'
If (!(Test-Path $file)) {
    throw '\deps\jsregexp not found'
}
(Get-Content $file).replace($find, $replace) | Set-Content $file
$file = '.\deps\jsregexp005\Makefile'
If (!(Test-Path $file)) {
    throw '\deps\jsregexp005 not found'
}
(Get-Content $file).replace($find, $replace) | Set-Content $file

$env:CHERE_INVOKING = 'yes' # Keep current Directory
$env:MSYSTEM = 'UCRT64' # https://www.msys2.org/docs/environments/
C:\msys64\usr\bin\bash -lc 'pacman --noconfirm -Syu'
C:\msys64\usr\bin\bash -lc 'pacman --noconfirm -S git'
C:\msys64\usr\bin\bash -lc 'pacman --noconfirm -S mingw-w64-ucrt-x86_64-luajit mingw-w64-ucrt-x86_64-make mingw-w64-ucrt-x86_64-gcc'
C:\msys64\usr\bin\bash -lc 'mingw32-make CC=gcc CFLAGS="-I/ucrt64/include/luajit-2.1 -O2 -Wall -fPIC" LDFLAGS="-shared -lluajit-5.1" install_jsregexp'

For the build option in lazy or wherever:

build = "pwsh " .. vim.fn.stdpath('config') .. "/luasnip_jsregexp_build.ps1",

Or run it manually in nvim-data/lazy/LuaSnip :

& "$env:USERPROFILE/appdata/local/nvim/luasnip_jsregexp_build.ps1"

Hope that helps. :) (edit: Added git install, Base Install add the start and the good recommandation to use stdpath('config') as script location for portability)

I'm on Windows 10. This solved it for me. Thank you so much! I was futzing around with mingw-w64-x86_64-lua and linker commands (of which I know little about). Should have come here first. My msys2 make output looked like this:

$ make install_jsregexp
git submodule init
git submodule update
make "CC=cc" "INCLUDE_DIR=-I'/c/users/kortantic/AppData/Local/nvim-data/lazy/luasnip/deps/lua51_include/'" LDLIBS="" -C "deps/jsregexp"
make[1]: Entering directory '/c/users/kortantic/AppData/Local/nvim-data/lazy/luasnip/deps/jsregexp'

...

cc -shared jsregexp.o cutils.o libregexp.o libunicode.o  -o jsregexp.so
C:/msys64/ucrt64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: jsregexp.o:jsregexp.c:(.text+0x11):

C:/msys64/ucrt64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: jsregexp.o:jsregexp.c:(.text+0x24):
undefined reference to luaL_optlstring'

...

collect2.exe: error: ld returned 1 exit status
make[1]: *** [Makefile:17: jsregexp.so] Error 1
make[1]: Leaving directory

I removed a couple hundred lines of missing lua references. Should be enough to help anyone seeing similar output. I'd recommend throwing the luasnip_jsregexp_build.ps1 in vim.fn.stdpath('config') or a child directory to help install neovim on another windows system if needed.

Is there any precompiled jsregexp for Windows?
