【问题描述】：
根据https://hyperledger.github.io/composer/installing/development-tools.html，我在 Ubuntu 系统上本地安装超级账本作曲家时遇到了困难。我想我已经满足了所有的要求：
ibmadmin@pfuntner1:~/hyperledger-composer$ cat /etc/os-release

ibmadmin@pfuntner1:~/hyperledger-composer$
当然，说明确实说我需要git 2.9.x 或更高版本，而我只有git 2.7.4，但我不确定这会导致问题或我看到的具体问题。当我尝试安装 composer-cli 时，我得到：
ibmadmin@pfuntner1:~/hyperledger-composer$ npm install -g composer-cli

我删除了大部分 npm install 输出，因为我认为它不相关而且很长。
按照说明，我没有以 root 身份运行，我没有安装想要访问/usr/lib/node_modules 之类的路径的权限并不感到惊讶。我从一个空目录运行，并且唯一创建为npm-debug.log 的东西。我该怎么办？
【问题讨论】：
-
虽然您没有运行 root，但您已经以 root 身份安装了节点（可能是通过执行 sudo apt-get install node ？），所以它被安装到只有 root 具有写入权限的目录中，所以您除非您是 root 或重新配置 npm 以解决此问题，否则无法全局安装 npm 模块。您基本上需要确保以您的正常 ID 安装节点，我建议使用 nvm 来执行此操作，因为它使整个过程变得容易。
