Node Version Manager (v0.35.3)

我在使用多个不同的命令时收到以下错误，即使只是打开我的终端我也会收到此错误。

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module 'npmlog'

nvm is not compatible with the npm config "prefix" option: currently set to ""
Run `npm config delete prefix` or `nvm use --delete-prefix v10.16.2 --silent` to unset it.

跑步

npm config delete prefix

env: node: No such file or directory

跑步

nvm use --delete-prefix v10.16.2 --silent

返回Cannot find module 'npmlog' 错误

nvm current

v10.16.2

当我跑步时

echo $PATH

我不再看到 npm 的 nvm 路径？

以前看过

/Users/{user}/.nvm/versions/node/v10.16.2/bin:

我正在使用zsh 这是我的.zshrc 文件

PATH="$HOME/.npm/bin:$PATH"
PATH="./node_modules/.bin:$PATH"
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
export VS_CODE_DEV_MODE=true
export PATH="$PATH:$HOME/.rvm/bin"

如果我安装新版本的节点，它可以工作，但是当我关闭终端并重新打开时，我又回到了原点。

nvm ls

       v10.16.2
       v10.16.3
       v14.15.5

lts/erbium -> v12.20.2 (-> N/A)

which node

node not found

和

which npm

似乎不是针对nvm

/Users/{user}/.npm/bin/npm

【解决方案1】：

如果您要排查问题是如何发展到当前状态的，可能有很多事情需要调查。但是，如果您只是想解决问题，那么重新安装nvm应该是无害且有效的。无需卸载（因为在现有 nvm 上安装与更新 nvm 相同）。

根据instructions on installing/updating，运行任一：

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

...或：

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

如果这不能解决问题，则有 a long-running issue in the nvm issue tracker about things people have done to fix weird issues on macOS。不过，您可能已经看到了，因为我看到您打开了an issue in the tracker for this。

还有 an issue all about nvm vs. zsh on macOS 如果您仍然卡住，可能值得细读。但是，如果我的快速浏览是正确的，则表明相关问题已在 nvm@0.37.0 中解决，并且您正在运行 nvm@0.35.3，因此似乎可以尝试更新。
