Following the upgrade of angular and @types/angular to version 1.6.x, an array of TS2694 errors suddenly appeared:
error TS2694: Namespace 'angular' does not include an exported member named 'material'
error TS2694: Namespace 'angular' does not include an exported member named 'ui'
error TS2694: Namespace 'angular' does not include an exported member named 'translate'
Previously, everything was functioning without any issues.
What do you think might be causing this problem?
After attempting to manually edit the file as suggested in the previous answer, I encountered some unexpected problems.
Each time I ran "yarn upgrade" or made changes to certain packages, the manual edits would be undone and my application would break once again.
To address this issue, I implemented a resolution in my package.json file to ensure consistent version resolving:
"resolutions": {
"**/@types/angular": "1.6.20"
},
The issue I encountered stemmed from conflicting angular type definitions within my node_modules directory. Specifically, Angular types were defined in both node_modules/@types/angular and
node_modules/@types/ng-file-upload/node_modules/@types/angularThis problem arose because yarn resolved angular with differing versions, resulting in two separate entries for angular with varying resolutions in the yarn.lock file:
"@types/angular@*":
version "1.6.7"
resolved "https://registry.yarnpkg.com/@types/angular/-/angular-1.6.7.tgz#8935a2b4a796fe7ca4f59f533f467804722fb0c4"
dependencies:
"@types/jquery" "*"
"@types/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1d7c737a68717c6f5d2c332b3365">[email protected]</a>":
version "1.6.32"
resolved "https://registry.yarnpkg.com/@types/angular/-/angular-1.6.32.tgz#fc791aad038227d9413eb5e552993e1076f8a509"
"@types/ng-file-upload@^11.1.31":
version "11.1.34"
resolved "https://registry.yarnpkg.com/@types/ng-file-upload/-/ng-file-upload-11.1.34.tgz#670fd0515c8e08668b27b7bbe30356b3b8011780"
dependencies:
"@types/angular" "*"
To resolve this issue, I initially tried removing the yarn.lock file and running 'yarn install' again. However, this caused modifications to many other dependencies which was not ideal.
Alternatively, using 'yarn install --flat' could have potentially fixed the problem, but I preferred not to alter how all dependencies are resolved.
In the end, I manually adjusted the yarn.lock file as follows:
"@types/angular@*", "@types/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9efff0f9ebf2ffecdeafb0a8b0e6">[email protected]</a>":
version "1.6.32"
resolved "https://registry.yarnpkg.com/@types/angular/-/angular-1.6.32.tgz#fc791aad038227d9413eb5e552993e1076f8a509"
"@types/ng-file-upload@^11.1.31":
version "11.1.34"
resolved "https://registry.yarnpkg.com/@types/ng-file-upload/-/ng-file-upload-11.1.34.tgz#670fd0515c8e08668b27b7bbe30356b3b8011780"
