我正在尝试在Ubuntu 14.04上安装Composer。我能够安装先决条件。安装composer时，我收到以下错误。如何解决？

首先，您不应将Hyperledger Composer安装为“root”。在继续https://hyperledger.github.io/composer/installing/development-tools.html

之前，您需要阅读此处的文档

所以从根本上说这是一个npm问题（因为当npm install作为'root'或'sudo'安装模块的权限时，它会导致npm出现问题。

我建议你在Ubuntu系统中创建一个非root用户。然后以该用户身份登录。然后使用上面链接中提供的prereqs-ubuntu.sh脚本安装pre-reqs。然后按照说明安装，作为非特权用户进行安装。

修复非root安装npm问题的正常途径，其中一个显示在https://docs.npmjs.com/getting-started/fixing-npm-permissions

当您全局安装编写器模块（例如，composer-cli）时，您应该使用指定的非root用户进行安装。如果存在问题（例如，在Ubuntu上有权编写/更新位于系统目录中的节点目录，如/ usr / local） - 一个解决方案（但请参见前面的链接）是对您可以访问的目录执行npm安装 - 而不是而不是诉诸于root或超级用户访问，因为这不是一个好习惯。以下是将npm前缀设置为给定目录的方法，...

“npm config set prefix / home / myuser /”

在这种情况下，全局二进制文件放在PATH中的/ home / myuser / bin中，模块放在/ home / myuser / lib ...
