by frank · August 19, 2020

yarn prettier:write

$ prettier --write --config .prettierrc --ignore-path .prettierignore '**/*.ts?(x)'
' was unexpected at this time.

Solution

Change single quotes to escaped double quotes. This is a Windows specific problem described here.

before:

"prettier:check": "prettier --check --config .prettierrc --ignore-path .prettierignore '**/*.ts?(x)'",

"prettier:write": "prettier --write --config .prettierrc --ignore-path .prettierignore '*/*.ts?(x)'",

after:

"prettier:check": "prettier --check --config .prettierrc --ignore-path .prettierignore \"**/*.ts?(x)\"",

"prettier:write": "prettier --write --config .prettierrc --ignore-path .prettierignore \"**/*.ts?(x)\"",
