node xx is not installed or cannot be found.

nvm切换Node版本技巧
本文介绍了使用nvm切换Node.js版本时常见的错误及其解决办法。重点在于如何正确指定版本号,以及确保命令行以管理员身份运行的重要性。

使用nvm切换node版本报错 node vv版本号 (64-bit) is not installed or cannot be found.

报这个错误一般需要写完整版本号,之前记得不用写完整的,遇到一个这个坑。可能是我记错了。

nvm use 完整版本号

如果只写nvm use 12 这样就会报错,会出现两个vv

还有需要注意的就是一定要用管理员运行命令窗口。windows的用户注意
