# npm、nvm

## 三者差異
tsc
ts-node
node

## 遇到 npm i 錯誤

npm ERR! code ERESOLVE                                        
npm ERR! ERESOLVE could not resolve
...
Could not resolve dependency:
npm ERR! Conflicting peer dependency:

...
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

遇到 npm i 錯誤問題，
先刪除 `package-lock.json` 以及 `node_modules`包，重新安裝試試
(等github套件方修好)

## 安裝 NVM

安裝完後記得重開IDE或Terminal才會生效

### Windows

https://github.com/coreybutler/nvm-windows/releases

下載並安裝

### MacOS

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

## 移除NVM

### Windows

開啟Bash

$ where nvm

$ cd C:/Users/User/AppData/Roaming/nvm/
$ ./unins000.exe


vim ~/.bashrc
移除掉

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

## nvm使用
