Failed to Detect Deno

I’m experiencing the same issue as https://github.com/justjavac/vscode-deno/issues/78; starting a new issue here since this seems to be the location of new development.

Mac Mojave 10.14.6 VS Code 1.45.0 VS Code Deno Extension version 1.27.0 Deno 1.0.0

Environment

$ deno info
DENO_DIR location: "/Users/ME/.deno"
Remote modules cache: "/Users/ME/.deno/deps"
TypeScript compiler cache: "/Users/ME/.deno/gen"
$ deno eval 'console.log(JSON.stringify(Deno.version))'
{"deno":"1.0.0","v8":"8.4.300","typescript":"3.9.2"}
$ env | grep -i deno
DENO_INSTALL=/Users/ME/.deno
DENO_DIR=/Users/ME/.deno
$ which deno
/Users/ME/.deno/bin/deno

I use zsh as my main shell environment.

I tracked the error down to https://github.com/denoland/vscode_deno/blob/9a684b5a735b17b6bedae9a64e68f0223cfe0988/client/src/utils.ts#L64 and saw it’s using execa. From the execa README.

Unless the shell option is used, no shell interpreter (Bash, cmd.exe, etc.) is used, so shell features such as variables substitution (echo $PATH) are not allowed.

I export DENO_INSTALL and DENO_DIR in my .zshrc file and add it to the path. Perhaps execa isn’t finding Deno because it’s not in the standard PATH locations?

Other people have encountered the same problem, so I should fix this problem

[hossam-magdy]

same problem encountered here too.

In case anyone lands here from google, a workaround is adding this to the end of ~/.zshrc:

[ ! -f "/usr/local/bin/deno" ] && ln -s "$DENO_INSTALL/bin/deno" "/usr/local/bin/deno"

… at least until the extension is fixed, to detect the executable from $DENO_INSTALL
