我用 npm更新了 /usr/bin/npm install -g npm@latest，但现在我得到了

/usr/local/lib/node_modules/npm/bin/npm-cli.js:85
      let notifier = require('update-notifier')({pkg})
      ^^^

知道这里有什么问题吗？

Answer 1

您的npm版本已完全过时。您正在使用npm v3.5.2，而npm v6.14.4已发布。

您需要升级npm才能使用--no-optional标志。为此，请参见:

docs.npmjs.com: Try the latest stable version of npm

You can upgrade to the latest version of npm using: npm install -g npm@latest

如何更新node.js

这是一个简单的解决方案，适用于所有受支持的操作系统，包括 Windows :

After a lot of surfing and not finding a straight solution, I just tried going to Node.js site, clicked the DOWNLOADS button on homepage and executed the installer program (MSI).

Thankfully it took care of everything and with a few clicks of 'Next' button I got the latest Node.js version running on my Windows machine.

(这是 original answer)



对于 Docker用户，这是官方的 Node.js image。

PS:要检查您的Node版本，请使用 npm version或 node --version。
PPS:密切关注 NodeJS blog - Vulnerabilities，这样您就不会错过重要的安全发布。
