Error while installing Bot Framework Emulator on Ubuntu

Question

I am unable to install microsoft emulator on ubuntu 16.04.

I downloaded BotFramework-Emulator-3.5.29.zip file from the portal, then extracted it and run npm install successfully (but got the following message):

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: 7zip-bin-mac@^1.0.1(node_modules/7zip-bin/node_modules/7zip-bin-mac):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: 7zip-bin-win@^2.1.0 (node_modules/7zip-bin/node_modules/7zip-bin-win):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"win32","arch":"any"} (current: {"os":"linux","arch":"x64"})

Then gulp build-app throws the following error:

[14:32:40] Using gulpfile /var/www/BotFramework-Emulator-3.5.29/gulpfile.js
[14:32:40] Starting 'clean'...

Maybe one strange thing: in package.json there is a dependency "typescript": "2.2.2", but in your log it says Compiling TypeScript files using tsc version 2.1.5. Isn't there a problem of TypeScript version?

Can you try to update Typescript to 2.2 and run everything again?

It seems that your error error TS2304: Cannot find name 'object'. is due to the fact that object is keyword in TS2.2 (see for example this reply stating the same)

add the latest dependancies in package.json, may be some dependancies version changed after development I changed all the version in package.json

"dependencies": {    "gulp-debug": "2.1.2",
"gulp-filter": "4.0.0",
"gulp-flatmap": "1.0.0",
"gulp-inject": "4.2.0",
"gulp-rename": "1.2.2",
"gulp-tsc": "1.2.6",
"gulp-util": "3.0.8",
"license-list": "0.1.3",
"object-assign": "4.1.0",
"tslib": "1.5.0",
"typescript": "2.2.2",
"vinyl": "2.0.1",
"vinyl-fs": "2.4.4"
},

then rebuild the gulp app

build gulp-app

then run the project with

npm start

this resolved me all issues and all works smooth
