Question

我是npm and hyperledger fabric-composer的新手问题：我的设置有什么问题？调查和解决此类错误的策略是什么？

我做了什么：

设置Ubuntu Linux 14.04 LTS（64位）
使用提供的脚本安装必备软件 https://fabric-composer.github.io/tasks/prerequisites.html

执行npm install会导致（不知道此信息是否足够）：

[...]

    urllib3.connection.match_hostname = match_hostname

我之前在trusty（14.04）上看到过这个问题，并且与python的过时urllib3库有关，它由docker compose使用。根据您安装的pip版本，您可以按如下方式更新urllib库

pip install --upgrade pip
pip install -U urllib3

Answer 2

您缺少权限，因此您需要执行sudo npm-install ...

Answer 3

此处的问题与安装脚本的最后一部分有关 - 这是安装docker-compose工具的部分。今天在干净的Ubuntu 14.04 LTS映像上进行测试，这就是原因。

我建议按照docker网站上的说明安装docker-compose。（https://docs.docker.com/compose/install/）

实际上这是

curl -L "https://github.com/docker/compose/releases/download/1.10.0/docker-compose-$(uname -s)-$(uname -m)" -o 
chmod +x /usr/local/bin/docker-compose

运行docker-compose --version以检查它是否已正确安装

$ docker-compose --version

docker-compose version: 1.10.0

然后像以前一样运行其余的Fabric Composer脚本。

我们正在更新脚本 - 但这应该让你去。

为什么我的Ubuntu安装时，Fabric Composer npm-install失败了？
