While working with the mobx library in my project, I encountered an issue after installing it using npm. Upon exploring the mobx/src/error.ts file within the node_modules folder, I came across a compile time error on line 78:
const errors: typeof niceErrors = __DEV__ ? niceErrors : ({} as any)
The specific error being:
The error message reads: Cannot find name 'DEV'.
My machine's typescript version is "typescript": "^4.3.5". How can I go about resolving this issue?
After navigating to my src directory, I decided to create a new folder called @types. Within that folder, I further created a subfolder named globals where I placed an index.d.ts file.
Within the index.d.ts file, I added the following code:
export {}
declare global {
declare const __DEV__: boolean;
}
This solution proved to be effective for me in resolving the issue.
