can't install expo-cli in the new win 10 1903

I installed node js 13.2 and I even tried installing yarn.
In visual studio installer I ticked C++ build tools and node js msbuild.
Yet whenever I install expo-cli globally I get these error:

^

I have the same problem.
OS: Win 10.
As I understood it's connected with envsub#3.1.0
The problem was fixed in new version of envsub but expo-cli still uses 3.1.0
P.S.
3.5.0 works
npm install -g expo-cli#3.5.0

Do the following:
expo init
follow the prompt.
You can either chose to install with Yarn or npm.
It works for me.

I fixed the problem, the answer is very simple :

Thanks in advance, Gopal R

I have solved this
Use this command npm install xml2json-light
and change let parser = require('xml2json'); to let parser = require('xml2json-light');
It worked for me

I have solved this. If you notice this part of the command else (node "" rebuild ) what I think is happening is that it is incorrectly evaluating if not defined npm_config_node_gyp as false and trying to run nothing instead of node-gyp. What you need to do is define your npm_config_node_gyp variable. You can do this like so:
export npm_config_node_gyp=<PATH_TO_NODE_GYP_PACKAGE_FOLDER> remember that Windows will need double backslashes. For me, it looked like this:
export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp
Edit:
There is another step after my fix. When executing my code, the expat bindings were missing. To fix it, add the bin folder and node-gyp executable to the npm_config_node_gyp variable and run node-gyp rebuild in the node_modules\node-expat folder. e.g.
export npm_config_node_gyp=C:\\Users\\781990\\AppData\\Roaming\\nvm\\v6.11.0\\node_modules\\node-gyp\\bin\\node-gyp.js
cd node_modules\node-expat
node-gyp rebuild

please guys give me the solution. how can I fix this problem?
i was try all the ubuntu commond. even I update node and npm to latest version. atill Getting the sam error.

As per documentation.
Install ImageMagick with headers before installing this module. Tested with ImageMagick 6.7.7 on CentOS 6 and Mac OS X Lion, Ubuntu 12.04 .
brew install imagemagick
or
sudo yum install ImageMagick-c++ ImageMagick-c++-devel
or
sudo apt-get install libmagick++-dev
Make sure you can find Magick++-config in your PATH. Packages on some newer distributions, such as Ubuntu 16.04, might be missing a link into /usr/bin. If that is the case, do this.
sudo ln -s `ls /usr/lib/\`uname -p\`-linux-gnu/ImageMagick-*/bin-Q16/Magick++-config | head -n 1` /usr/local/bin/
Then do :
npm install imagemagick-native

Have you tried updgrading npm to v4.x?
npm install npm#latest -g
I had problems with 3.10.6 with shrinkwrap and the fsevents package which is Mac Os specific. If I deleted the npmshrinkwrap.json file I could run npm i and it would run fine. Once I upgraded to v4.0.3 of npm it worked with shrinkwrap. This all assuming you use shrinkwrap of course.

Looks like the problem is related to this:
The Windows SDK version 8.1 was not found. Install the required
version of Windows SDK or change the SDK version in the project p
roperty pages or by right-clicking the solution and selecting
"Retarget solution".
[C:\Users\Pirate\Desktop\Nem\nem_find\node_modules\node-expat\build\deps\libexpat\expat.vcxproj]
You need to install Windows SDK before you can recompile using node-gyp.

Check again into your package.json file their is available node-gyp module or not with version ID if there is not available then add and again install from npm.

I made a comment on top but It's necessary to let everyone know.It took me only 15 mins to set everything I mean everything on Debian.
My advice is to move to mac or Linux, I respect what #Microsoft is doing with there cloud and all but on windows they haven't got it yet, it will take them another 10 years to solve the issues of development community. You ask any i mean any developer working with MEAN Django or ROR they will not recommend windows just simply because its not reliable you cannot trust windows.....sad:(

Updates:
-Interesting detail: I was never prompted for my password
-found a discussion thread on the topic. Reading through it now:
-just installed node-gyp
-also installed node-fibers

I did an "apt-get install -y build-essential" and everything was fine after that ;-)

I just upgraded from python 2.5.4 to 2.7.9. I was told that that might help....And it did!
