Subsequent variables declarations must have the same type

[juaal12]

Hi,

I am facing an issue when trying to build an angular package. It seems that "crypto" variable is declared several times with different "Crypto" types. I have been digging a bit and it seems crypto is declared globally at @types/node/ts4.8/crypto.d.ts:4477:13 and also at typescript/lib/lib.dom.d.ts:18084:13 dropping this an error when trying to build.

DevOps pipeline message:

I am using Nuke build and my package is being generated from a TS client generated by NSwag.

DefinitelyTyped/types/node/ts4.8/crypto.d.ts

Line 4477 in f58f900

var crypto: webcrypto.Crypto;

same issue coming for me.. how to solve this?

@girirajawari1

In my case, since I am using Nuke build, I added a new step which after creating a new angular project using ng new my-workspace --no-create-application executes npm package npm install --save-dev @types/node@20.11.5.
This is a workaround that works for me. Downgrading the package version from 20.11.10 to 20.11.5 worked for me but I do not know if it will work for you since I do not know your application/environment needs.

But I would like to have a better and official solution 😅.

Will be fixed in #68371

Temporary workaround for me, was to use resolutions on package.json to force downgrading to version 20.11.7 (the one that was resolved at last sucessful build for my app)

...
"resolutions": {
     "**/@types/node" : "20.11.7"
},
...

This worked for me

Thank you

20.11.6 worked for me same error on 20.11.7

[RamMohanSonte]

Both the versions 20.11.7 and 20.11.6 versions did not work out for us

"resolutions": {
"**/@types/node" : "20.11.7"
},

Error is

Error: node_modules/@types/node/ts4.8/crypto.d.ts:4477:13 - error TS2403: Subsequent variable declarations must have the same type. Variable 'crypto' must be of type 'Crypto', but here has type 'Crypto'.

4477 var crypto: webcrypto.Crypto;
~~~~~~

node_modules/typescript/lib/lib.dom.d.ts:18084:13
18084 declare var crypto: Crypto;
~~~~~~
'crypto' was also declared here.

@RamMohanSonte do this in your devDependencies:

"devDependencies": {
"@types/node" : "20.11.7"
}

[jakebailey]

I just merged a PR which should fix this: #68371

In a half hour when the package is published, please test and let me know if it works.

[kanadgodse-lh]

I solved it by adding "skipLibCheck": true in tsconfig.json

[WagaoFC]

@jakebailey thank you very much for the solution. It worked perfectly here.
