無法將 Truffle Framework 安裝到 Mac OS Big Sur

所以我檢查了我是否有最新版本的nodejs，結果證明我有。

kalebamarante$ node -v
v15.5.0

然後我嘗試安裝一個 Truffle 版本，但沒有成功

~ kalebamarante$ npm install --g truffle@5.1.39
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/truffle
npm ERR! errno -13

npm ERR!   path: '/usr/local/lib/node_modules/truffle'

然後我去了松露網站並將新連結複製到我的終端中，這發生了。

我正在嘗試做一個更大的項目，在安裝松露之前我無法繼續前進。我很感激我能得到的所有幫助！！

謝謝你

我設法通過首先安裝 HomeBrew 來做到這一點，您可以通過以下連結獲得它：https ://brew.sh/

在開始使用 brew 命令之前，您必須輸入此內容export PATH="/opt/homebrew/bin:$PATH"

之後輸入brew update

然後在你成功更新後去brew install node

完成以上所有操作後，您可以再試npm install -g truffle一次。到這裡你應該不會收到任何錯誤，至少我可以成功安裝松露。但是在我的 macOS Big Sur 版本 11.5.1 中使用 truffle 命令仍然有問題。

希望這會對​​您有所幫助並祝您好運。

您遇到了權限問題。MacOS 是基於 Linux 的作業系統。基於 Linux 的作業系統需要管理權限才能對根目錄進行編輯更改。在 MacOS 上，您只需要使用sudo命令執行：

sudo npm install --g truffle@5.1.39
