为 pub 命令配置环境变量
Environment variables allow you to customize pub to suit your needs.
PUB_CACHE- Some of pub’s dependencies are downloaded to the pub cache.
By default, this directory is located under
$HOME/.pub-cache(on macOS and Linux), or in%LOCALAPPDATA%\Pub\Cache(on Windows). (The precise location of the cache may vary depending on the Windows version.) You can use thePUB_CACHEenvironment variable to specify another location. For more information, see The system package cache. PUB_HOSTED_URL- Pub downloads dependencies from the pub.dev site.
To specify the location of a particular mirror server,
use the
PUB_HOSTED_URLenvironment variable. For example:
PUB_HOSTED_URL = https://pub.example.com
