Question

我很难按照https://hyperledger.github.io/composer/installing/development-tools.html在Ubuntu系统上本地安装hyperledger作曲家。我想我已经满足了所有要求：

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，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npm install输出的大部分内容，因为我认为它不相关而且很长。

根据说明，我没有以root用户身份运行，并且我没有意识到我没有安装所需的访问权限/usr/lib/node_modules这样的路径。我是从一个空目录运行的，唯一创建的是npm-debug.log。我该怎么办？

所以从根本上说这是一个npm问题。但是很高兴看到你的npm版本。

正常路线是这里显示的其中一条路线 https://docs.npmjs.com/getting-started/fixing-npm-permissions

理想情况下，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 - 正如您确实尝试的那样。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，...

＆＃34; npm config set prefix / home / myuser /＆＃34;

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 ...
