golang

g

# It is recommended to clear the `GOROOT`, `GOBIN`, and other environment variables before installation.
$ curl -sSL https://raw.githubusercontent.com/voidint/g/master/install.sh | bash
$ cat << 'EOF' >> ~/.bashrc
# Check if the alias 'g' exists before trying to unalias it

node

nvm

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash

$ nvm install --lts
$ nvm use --lts

使用 nvm 要注意多版本，比如 gemini 装到 A 版本 node，但目前是在用 B 版本 node，调用会提示找不到
