首先，你可以尝试关闭当前终端选项卡，并打开新的工作

只要确保semver已经安装:npm install -g semver

这适用于我的Ubuntu(最新版本日期为2020年10月)

我必须首先从bash源代码中获取代码:

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -

这得到了更新我的库的节点的最新版本，并摆脱了'semver'错误。

对我来说，这发生在我在全球安装纱线之后。 为了解决这个问题，使用yarn安装npm。

yarn global add npm

只需删除/node_modules文件夹，然后重试。,)

你可以使用npm rm来删除它。

你也可以在GitHub上检查这个问题。 更具体地说，unnistal是这样的:

Uninstalling So sad to see you go. sudo npm uninstall npm -g Or, if that fails, sudo make uninstall More Severe Uninstalling Usually, the above instructions are sufficient. That will remove npm, but leave behind anything you've installed. If you would like to remove all the packages that you have installed, then you can use the npm ls command to find them, and then npm rm to remove them. To remove cruft left behind by npm 0.x, you can use the included clean-old.sh script file. You can run it conveniently like this: npm explore npm -g -- sh scripts/clean-old.sh npm uses two configuration files, one for per-user configs, and another for global (every-user) configs. You can view them by doing: npm config get userconfig # defaults to ~/.npmrc npm config get globalconfig # defaults to /usr/local/etc/npmrc Uninstalling npm does not remove configuration files by default. You must remove them yourself manually if you want them gone. Note that this means that future npm installs will not remember the settings that you have chosen.

我也犯了同样的错误。npm uninstall npm -g, rm -rf node_modules没有帮助我，因为当我尝试时，我得到错误:无法找到模块'semver'。但是我用这些步骤解决了我的问题(这将删除你可能正在使用的其他全局模块):

Sudo rm -rf /usr/local/lib/node_modules Sudo rm -rf ~/.npm 酿造卸载——force节点 Brew安装节点

希望这能帮助到那些有类似问题的人。
