Also note that running the tests in the typescript directory in the main repo also has the same failure.

Sorry to bump, but any comment would be appreciated. This is in the main release and a blocker for starting a new project with TypeScript.

Hi managed to figure this out. For me it was the environment variable BROWSER was set to firefox. I cleared this environment variable by doing export BROWSER= and this worked

[bholtbholt]

@daniel-lahlafi I cleared this environment variable by doing export BROWSER=

Would you mind expanding on this? I'm running into the same issue but am not sure where to export BROWSER=. I've added it to the CLI, like BROWSER= anchor test, or BROWSER='' anchor test but neither work.

Just run the command I wrote in the terminal before running anchor

export BROWER= worked just fine here. Thanks !

[masamizu]

above comment is missing "S" in BROWSER. export BROWSER= worked fine also here thanks!

[Plitskine]

In most recent versions of anchor, the exported 'Provider' was moved to 'AnchorProvider'.

Had the same issue, but this was the problem !

[Yakkhini]

a little graceful command:

unset BROWSER

whatever, just make sure BROWSER environment variable unset then this issue would be fixed. ; )

Error: Provider env is not available on browser. I have the same error but in my front end anyone one can help me please

BROWSER= anchor test, or BROWSER='' anchor test Thank you. Above command works well.
