Breaks with VS2019 installed

[TanninOne]

node-gyp version 4.0.0
I have vs2015, vs2017 and vs2019 installed, I need them for different projects so uninstalling one isn't really an option.

As far as I can tell, if I use msvs_version=2017, the autodetection now finds the setup for 2019 and then fails to construct the correct path for msbuild which is now at
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\MSBuild.exe
instead of
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\15.0\Bin\MSBuild.exe
as node-gyp seems to expect.

Now I'm fine with running the proper 2017 or 2019 and overwriting the msbuild path, doesn't really matter to me, but I can't find how to configure either.
I can apparently overwrite the msbuild path with the command line "--msbuild_path" and thus use vs2019 but the same parameter set globally through "npm config" seems to have no effect.
Any hints?

[ilya-edrets]

Run into the same problem.

[jyxjjj]

Mark.
Me too.
Use "--msbuild_path" successfully & use "npm config" or "--msvs_version" failed.

Running this command seems to fix the issue on my system:
npm config set msbuild_path "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\MSBuild.exe"

Thank you so much! We've been pulling hair about this for a long time.

运行此命令似乎解决了我的系统上的问题：
npm config set msbuild_path "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\MSBuild.exe"

No, This won't fix mine.
I can only "--msbuild_path" param at every command, and must be 2017 version.

[jyxjjj]

prefix=D:\Program Files\NodeJS
cache=D:\Program Files\NodeJS\npm_cache
msbuild_path=C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe

Set the file "D:\Program Files\NodeJS\node_modules\npm\npmrc" fixed.

[Vultraz]

Can confirm this setup works

msbuild_path = "C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\MSBuild\\Current\\Bin\\MSBuild.exe"
msvs_version = "2017"

(set with npm config)

Using npm config set msvs_version 2019 causes its own problems:

@joaocgreis it seems like 360ddbd should have fixed this is it possible to get a new release cut?

But, some projects cannot be built with 2019.

node-gyp v5.0.0 is out with Visual Studio 2019 support. It's not yet integrated into npm so it has to be installed manually. This should do it (only need to be run once):

Windows Command Prompt

npm install --global node-gyp@latest
for /f "delims=" %P in ('npm prefix -g') do npm config set node_gyp "%P\node_modules\node-gyp\bin\node-gyp.js"

Powershell

npm install --global node-gyp@latest
npm prefix -g | % {npm config set node_gyp "$_\node_modules\node-gyp\bin\node-gyp.js"}

That is, install node-gyp globally and make the npm config variable node_gyp point to node-gyp.js.

How to undo this after node-gyp is integrated into npm

npm uninstall --global node-gyp
npm config delete node_gyp

[VideoBeam]

Thanks a million joaocgreis. I am using VS 2019, along with node v10.16.2 and npm V 6.9.0.
Your suggestion resolved gyp build issues with several npm installs, including:
'npm install onoff' and 'npm install serialport'.

[TonieMwega]

npm install --global windows-build-tools

[cclauss]

npm install --global windows-build-tools

I believe that will currently install VS 2017 and Python 2.7.17 which might not be desired in this case.

[Pointotech]

node-gyp has to be the messiest NPM package in existence. I'm trying to write Javascript and suddenly I'm in Microsoft dependency hell. What?

[rvagg]

@Pointotech then stop trying to use non-javascript packages that need to be compiled, that's why you're here and Windows is the most difficult platform to be doing this. Clean your dependency tree and keep your catharsis off our issue tracker.

Changing node version to 10.5.0 resolve this problem.

Such a low version. I remember that there is a single 2017 complier installer, that means we need not to install the full 2017 and i have not met again this problem.
I think it is necessary to update python and vs version for Node/NPM.
Many things are out of service.

--And btw, this issue is closed. create or find a newer to metion this issue id.

For me the solution was to uninstall node 12.x and install version 10.21 (11.x might also work)

[josteink]

When installing Visual Studio 2017 C++ Build Tools v141 using Visual Studio Installer, I was able to make this build, even when running latest Visual Studio, with no additional configuration required.

Wow you are dense

[stewartbright]

For anyone that has not yet (or cannot) updated node on build servers, something like this also seems to work around the issue until you can update node. Basically, you set the vc build environment using vcvarsall.bat from 2017 before running npm install.

$VcVarsall = (Get-ChildItem -Path "C:\Program Files (x86)\Microsoft Visual Studio\2017\**\vcvarsall.bat" -Recurse).FullName
cmd /c "`"$VcVarsall`" x64 && npm install"

Installing MSVS v141 fixed it.
