Unable to install @tensorflow/tfjs-node

I am unable to install @tensorflow/tfjs-node. I’d appreciate it if someone can shed some light and let me know what I’m missing. I’m running the following:

• Windows 10 Pro version 1803
• node v10.13.0
• npm 6.4.1
• Python 2.7.15

C:\Users\jcruz\Documents\nodejs\demo>node -v

hi @nightBaker

can you run npm install --production windows-build-tools and then try to install tfjs-node? I used to have a similar MSBUILD error and reinstall windows-build-tools resolved it.l

@nkreeger, I took a look at https://github.com/nodejs/node-gyp/issues/119#issuecomment-331778053 and I think that solved my problem.

Though when I first tried to install the windows-build-tools package, I got an error because I didn’t run from an elevated Command Prompt. But when I opened a Command Prompt that had administrative privileges, the install went smoothly, albeit slowly (took about 5 minutes).

First I installed windows-build-tools:

C:\Users\jcruz\Documents\nodejs\demo>npm install --production windows-build-tools

> windows-build-tools@5.0.0 postinstall C:\Users\jcruz\Documents\nodejs\node_modules\windows-build-tools
> node ./dist/index.js

Downloading vs_BuildTools.exe
[>                                            ] 0.0% (0 B/s)
Downloaded vs_BuildTools.exe. Saved to C:\Users\jcruz\.windows-build-tools\vs_BuildTools.exe.

Starting installation...
Launched installers, now waiting for them to finish.
This will likely take some time - please be patient!

Status from the installers:
---------- Visual Studio Build Tools ----------
Successfully installed Visual Studio Build Tools.
------------------- Python --------------------
Python 2.7.15 is already installed, not installing again.

Now configuring the Visual Studio Build Tools..

All done!

Then I installed @tensorflow/tfjs-node:

Aside from some warnings, looks like I was finally able to install @tensorflow/tfjs-node!

Thanks much @nkreeger for the help!
