How can I force Cspell to use the french variant Dictionnaire "Réforme 1990"?

@Jason3S so I tried to build, but it says that cp command does not exist. Then I tried in bash, and cp seems ok but now it's cspell-tools that is not recognized as a command so the build fails:

'cspell-tools' n’est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! cspell-dict-fr-fr-1990@1.0.0 build: cspell-tools compile-trie "fr-reforme1990.dic" -o . npm ERR! Exit status 1 ...

Are there requirements that are not mentioned in "How to create a new dictionary"?
