I'm guessing you ran yarn add @types/@reach/router, trying to install the @types package for the scoped package @reach/router, but that command is actually parsed as installing a package named @types/ at version reach/router. Main issue is that you changed typeRoots in your tsconfig, which by default is node_modules/@types. I have an angular 6 application and I'm using karma + jasmine to run my tests. I fixed the error by deleting the node_modules directory from the project root. I didn't realized that in my tsconfig.spec.json I was using jest instead of jasmin in types node.

Bloats your builds and in some cases confuses Jest about which files to run and breaks testing. The text was updated successfully, but these errors were encountered: It would be helpful to see the tsconfig.json file too, but my guess would be that setupTests.ts is not being included as a source file in the TypeScript config when compiling the tests, which means TypeScript would never see the import statement and would therefore not augment the jest namespace. Assume we have sample fizz buz to test. #mc_embed_signup{background:#fff;clear:left;font:14px Mulish,sans-serif}#mc_embed_signup .button{margin-left:16px!important;background-color:#1875f7!important;height:50px!important;font-weight:700}#mc_embed_signup .button:hover{background-color:#0475c8!important}#mce-EMAIL{height:50px;font-size:1.1em}#post-end-cta-image{height:550px;width:auto;box-shadow:0 0 10px #c0c0c0}, (function($){window.fnames=new Array();window.ftypes=new Array();fnames[0]='EMAIL';ftypes[0]='email';fnames[2]='LNAME';ftypes[2]='text';fnames[3]='ADDRESS';ftypes[3]='address';fnames[4]='PHONE';ftypes[4]='phone';fnames[5]='BIRTHDAY';ftypes[5]='birthday';fnames[1]='GIVEAWAY';ftypes[1]='text'})(jQuery);var $mcj=jQuery.noConflict(!0)var target=document.getElementById('mce-success-response');var successResponseShown=!1;var observer=new MutationObserver(function(mutations){for(var i=0;i wrote: which your tests are.!
