Fresh Generated Sample Program get errors on compile, cannot proceed development

[richso]

Bug

running the below command line for trial view of the freshly generated sample project got a lot of following errors

command line: dojo build --mode dev --watch --serve

msg / errors on the console (listed some similar errors in various line of @types/babel-types): ℹ cli-build-app: 8.0.0 ℹ typescript: 3.5.3 ✔ hash: 014fccf5fcda607f5565 ✖ errors: 681 ⚠ warnings: 0

The build completed with errors. Listening on port 9999 Please note the serve option is not intended to be used to serve applications in production.

Same For dojo7: ℹ cli-build-app: 7.0.5 ℹ typescript: 3.4.5 ✔ hash: 227fa3e70c5aa3b7fe66 ✖ errors: 681 ⚠ warnings: 0 ...

Package Version: cli-build-app: 8.0.0 typescript: 3.5.3 OR cli-build-app: 7.0.5 typescript: 3.4.5

Example (command lines, default generated project):

dojo create app --name dojo7-test cd dojo7-test dojo build --mode dev --watch --serve

Expected behavior: There should be no compilation errors

Actual behavior: The dev web server started at port 9999 for dojo8 (but terminated for dojo7) and the web page displayed normally upfront, however on modifying some of the display text on the e.g., Home.ts file to trigger re-compilation, errors like the above appeared on the web page.

Supplementary info: MacOS 12.2 npm version 6.14.10

@richso sorry for the delayed reply on this and thanks for reporting 👍 . looks like unfortunately babel-types (which comes from another dependency) has types that are not backwards incompatible with older versions of typescript. we'll look at how we can pin those to fix @dojo/cli-build-app

Unfortunately, the same problem still happened when I tried on a Mac (MacOS Monterey 12.3) and Linux (AWS 2 VM):

• I've remove the previous installed @dojo/cli and @dojo/cli-create-app
• then re-installed a clean version by command: npm i @dojo/cli @dojo/cli-create-app -g (BUT I found the installed @dojo/cli and @dojo/cli-create-app are still in version of 8.0.0, there is no 8.0.1)
• create a test app with command: dojo create app --name test --tsx
• build the app via: dojo build --mode dist BUT it failed to build with errors similar to previously reported; however I discover the installed @dojo/cli-build-app package version is 8.0.0 and NOT 8.0.1
• so I then install the 8.0.1 build by: npm i @dojo/cli-build-app@8.0.1
• then build with 8.0.1 version again via: dojo build --mode dist BUT it still failed with similar errors

I am very disappointed and I am about to abandon to use dojo for future projects, sorry.

Will take another look today, and also make 8.0.1 latest an oversight on our side.
