Cannot install moustachu in Nim 2 (plus workaround - see comment) #25

I use Moustachu for my Nim-apps so help would be appreciated... I work with nim 2.02 Cannot install moustachu on my new second-hand laptop (Linux Mint 21.2), getting the following report:

nimble install moustachu Downloading https://github.com/fenekku/moustachu.git using git Verifying dependencies for moustachu@0.14.0 Installing commandeer@>= 0.10.4 Downloading https://github.com/fenekku/commandeer using git Verifying dependencies for commandeer@0.12.3 Installing commandeer@0.12.3 Success: commandeer installed successfully.

[y/N]

I have tried above option but it fails aswell:

Apparently parseopt2 is a deleted nim-module in Nim 2, while Commandeer is still using it. Hence the installation fails. Updating it to parseopt might do the trick (?)

For the impatient one can use the following workaround to install it: -activate an older version of Nim, so run: choosenim 1.6.18 -install moustachu with this older version, so run: nimble install moustachu -switch back to the latest Nim, so run: choosenim 2.0.2

Apparently the installation of Moustachu is not version-dependent.. By the way I forgot to thank Fenneku and others to contribute this nice lib !!!
