bug 记录

首先，是想本地安装lighthouse进行网站优化检测，安装好后运行命令报错

lighthouse
/usr/local/lib/node_modules/lighthouse/lighthouse-core/gather/driver.js:68
  _traceCategories = Driver.traceCategories;
                   ^
SyntaxError: Unexpected token =

    at Module.require (internal/modules/cjs/loader.js:637:17)
    at require (internal/modules/cjs/helpers.js:20:18)

查了下相关issues,lighthouse版本要求node最低v12 issues (opens new window)

于是继续升级node，由于我是用homebrew安装的node，所以直接

brew upgrade node

升完级node版本14，lighthouse成功运行。

然后，npm 报错了

internal/modules/cjs/loader.js:1083
  throw err;
  ^

Error: Cannot find module '../lib/utils/unsupported.js'

  requireStack: [ '/usr/local/lib/node_modules/npm/bin/npm-cli.js' ]
}

查了半天，最终彻底卸载重装得已解决。

brew uninstall node
#Error: Refusing to uninstall /usr/local/Cellar/node/14.8.0
#because it is required by yarn, which is currently installed.
#You can override this and force removal with:

brew uninstall --ignore-dependencies node

sudo rm -rf /usr/local/lib/node_modules/npm

brew install node
