我在Ubuntu16.04LTS中安装松露时出错。如何解决这一问题？

Question

输入以下命令时：sudo npm install -g truffle

我得到以下错误：

> truffle@5.0.27 postinstall /usr/lib/node_modules/truffle
> node ./scripts/postinstall.js

Error: EACCES: permission denied, open '/home/nslabiitp/.config/truffle/config.json'

我的修正是升级到节点v12.6 错误:权限被拒绝，打开‘/root/.config/tru显/config.json’

我确实尝试过几次修复，因此上面的解决方案可能不是您的情况，但是，至少用高于节点v10的版本进行测试是很重要的，因为在github网页中提到了这个版本上的其他问题。
