Saya memperbarui sudut saya ke v9 dan ketika saya mencoba untuk kembali ke v8, saya menerima kesalahan ini. Saya sudah mencoba yang berikut ini:
- uninstall -global angular / cli
- uninstall angular / cli
- kembali ke package.json terakhir saya
- hapus folder node_module
- hapus repo
Kesalahan ini terus muncul.
Stacktrace saya adalah:
An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.
See angular-errors.log for further details.
angular-errors.log:
[error] Error: Job name "..getProjectMetadata" does not exist.
