Definitelytyped: [@types/jest] TS1005: ';' expected.

[Leaf27]

Hello,

I have a typeScript project, which uses "typescript": "2.4.2" and "@types/jest": "^23.3.13". Previously, I had package-lock.Json, and project could be built and run without any errors. While after removing package-lock.Json, build failed with the following errors:

ERROR in /node_modules/@types/jest/index.d.ts
[tsl] ERROR in /node_modules/@types/jest/index.d.ts(39,22)
      TS1005: ';' expected.

ERROR in /node_modules/@types/jest/index.d.ts
[tsl] ERROR in /node_modules/@types/jest/index.d.ts(39,46)
      TS1005: '=' expected.

ERROR in /node_modules/@types/jest/index.d.ts
[tsl] ERROR /node_modules/@types/jest/index.d.ts(220,81)
      TS1144: '{' or ';' expected.

ERROR in /node_modules/@types/jest/index.d.ts
[tsl] ERROR in /node_modules/@types/jest/index.d.ts(220,161)
      TS1005: '(' expected.

ERROR in /node_modules/@types/jest/index.d.ts
[tsl] ERROR in /node_modules/@types/jest/index.d.ts(220,168)
      TS1005: ')' expected.

I have no clue why package-lock.json matters. Any help is appreciated

I have same Issue 😢

[Link631]

I have same issue too. I can not compile when i have jest installed and added a test with describe...

[david-shortman]

Anyone out there found a resolution?

[chasmaca]

Anyone could resolve this problem?

This sounds like something that can be solved via StackOverflow.

unless a bug is reported with more detail.

seems similar to https://github.com/facebook/create-react-app/issues/8714.
guess the @types/jest package you installed used some syntax that your typescript version not yet supported.

suggestion:

1. go to the line that the error was thrown at, e.g. "/node_modules/@types/jest/index.d.ts(39,22)".
2. see what syntax it's using and since which version typescript supports that, if it doesn't match your currently installed typescript version, then you find the cause.
3. if step2 hits, upgrade typescript or downgrade @types/jest; if not, well, good luck for your next solution.

One syntax that was recently added is import type and Jest v16 is only compatible with TS v3.8 if that helps.

Edit: sorry, I actually meant Jest v26, which only supports TS >v3.8.
See Jest’s changelog, always do that before upgrading to a new major version. Jest provides its own types with v26 so @types/jest is not needed. But it requires some additional steps, e.g. it doesn’t expose global expect, it etc. anymore AFAIK.
