使用 yarn install 安裝vue項(xiàng)目依賴時(shí)出現(xiàn)網(wǎng)絡(luò)連接問題如下：

yarn install v1.22.5
[1/4] Resolving packages...
success Already up-to-date.
Done in 0.70s.

info There appears to be trouble with your network connection. Retrying...

查閱資料之后發(fā)現(xiàn)可能是yarn的鏡像地址有問題，

$ yarn config list
yarn config v1.22.5
info yarn config
{
  'version-tag-prefix': 'v',
  'version-git-tag': true,
  'version-commit-hooks': true,
  'version-git-sign': false,
  'version-git-message': 'v%s',
  'init-version': '1.0.0',
  'init-license': 'MIT',
  'save-prefix': '^',
  'bin-links': true,
  'ignore-scripts': false,
  'ignore-optional': false,
  registry: 'https://registry.yarnpkg.com',
  'strict-ssl': true,
  'user-agent': 'yarn/1.22.5 npm/? node/v14.17.5 linux x64',
  lastUpdateCheck: 1629429645750
}
info npm config
{
  registry: 'http://r.npm.taobao.org/'
}
Done in 0.06s.

可也看到鏡像是yarn官方鏡像地址，通過更換淘寶鏡像地址解決問題，

$ yarn config set  registry https://registry.npm.taobao.org
yarn config v1.22.5
success Set "registry" to "https://registry.npm.taobao.org".
Done in 0.06s.

經(jīng)過查閱如果是網(wǎng)絡(luò)環(huán)境較差可以加上限制超時(shí)時(shí)間參數(shù)進(jìn)行緩解，具體如下：

yarn install --network-timeout 100000
