为以太坊开发安装松露的 npm 错误

如何解决为以太坊开发安装松露的 npm 错误

当我尝试使用 npm 安装 truffle 时，会出现以下输出：

我认为这是因为我没有 root 管理员的访问权限。我尝试重新启动我的电脑，但它仍然无法正常工作。还有一个错误，其中提到了有关我的操作系统的内容。我没有任何想法，因为我是以太坊开发的新手。

解决方法

是的，您需要管理员权限才能全局安装 NPM 包，在命令前加上 sudo：

sudo npm install -g truffle

,

我也有这个问题，似乎问题是如何在 npm 上管理或部署 truffle 包，我改为使用：

yarn global add truffle

它奏效了。请尝试一下。根据我的经验，npm install -g truffle 在 Linux Ubuntu 20.04 设置（这是我的环境）上不起作用，但是当我在 WSL Ubuntu 20.04 终端上运行它时它起作用了。松露团队可能会记住这一点。我还意识到使用 sudo npm install -g truffle 时会有警告，所以不要使用它。
