我不能在NodeJS中使用命令提示符使用npm install。我在运行npm install时得到这些错误:

module.js:339
    throw err;
    ^
Error: Cannot find module 'semver'

只需删除你的node_modules

rm -rf node_modules

than

yarn

or

npm install

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.

我也有同样的问题,但这是由损坏的包裹锁引起的。json文件。

删除package-lock。Json和运行NPM install再次为我修复了它。

在Ubuntu上,如果你想通过默认的存储库使用apt来管理Node,最好同时安装nodejs和npm。

你正在使用的npm版本很有可能在某个特定的位置期望与你已经安装的Node JS版本不一致。如果只有一个版本的nodejs和一个版本的npm,并且它们都是使用默认存储库安装的,这应该可以完美地工作。

下面是我的最佳指导,让Node和npm使用Ubuntu的主要存储库工作:

sudo apt-get purge nodejs --auto-remove and sudo apt-get purge npm --auto-remove whereis node: remove all the versions of node, one at a time. Repeat until this command returns a blank after node:. sudo apt-get install nodejs node --version: should return ... no such file or directory nodejs --version: should return v1x.x.x. This is the version installed by apt. It will probably be less recent that the latest version available on the Node JS website. sudo apt-get install npm npm --version: it will use the nodejs installed by apt and work correctly.

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。

在Arch Linux上,我的诀窍是:

sudo pacman -Rs npm
sudo pacman -S npm
