并非所有的先决条件都可以为Hyperledger Composer正确安装 [英] Not all pre-reqs install correctly for Hyperledger Composer

问题描述

我一直在关注Hyperledger Composer教程.我设法在Windows 10 Enterprise的Hyper-V上安装Ubuntu 16.04.然后，我开始按照以下先决条件安装说明进行操作: https://hyperledger.github.io/composer/installing/installing-prereqs. html

I've been following the Hyperledger Composer tutorial. I managed to install Ubuntu 16.04 on Hyper-V on my Windows 10 Enterprise. I then started on the following pre-req installation instructions: https://hyperledger.github.io/composer/installing/installing-prereqs.html

我运行了prereqs-ubuntu.sh脚本.运行正常，没有错误.我检查了日志，发现它已成功安装了npm 5.6.0，节点8.9.4，docker 17.12.x，docker composer 1.13.x和Python 2.7.12.

I ran the prereqs-ubuntu.sh script. It ran fine with no errors. I examined the logs and saw that it had successfully installed npm 5.6.0, node 8.9.4, docker 17.12.x, docker composer 1.13.x, and Python 2.7.12.

但是，当我运行时，运行$ sudo npm --version 它告诉我找不到npm命令

However, when I run run $ sudo npm --version it tells me that the npm command is not found

与$ sudo node --version相同 找不到...?！

Same with $ sudo node --version Not found...?!

为什么在日志中清楚显示npm和成功安装节点的情况下?！

Why would that be when the log clearly shows that npm and node where successfuly installed?!

推荐答案

好吧，我做了什么并通过以下方式进行了管理:

Well, what I did and managed through:

->安装nodejs和npm:

--> install nodejs and npm:

sudo snap install node --classic --channel=8

这样您可以获得最新的node8.

so you get the latest node8.

->然后要解决节点的"sudo"问题，请指定npm前缀:

--> then to solve "sudo" problem with node specify the npm prefix:

npm config set prefix ~/.node_modules

将以下内容添加到.bash_profile

add the following to .bash_profile

export PATH=$HOME/.node_modules/bin:$PATH

现在，这些软件包将安装到您的用户目录中，并且不会损害任何权限.

Now the packages will install into your user directory and no permissions will be harmend.

->安装nvm(在下一步中准确获取节点8.9版本):

--> install nvm (to get exactly node 8.9 version on the next step):

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

或

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

验证:

node -v nvm

如果安装成功，应该输出"nvm".

which should output 'nvm' if the installation was successful.

->获取并设置节点8.9版本:

--> get and set node 8.9 version:

nvm install v8.9.0 
nvm use 8.9.0

->重置PATH:

echo export PATH="$HOME/npm/bin:$PATH" >> ~/.bashrc
npm config set prefix ~/npm
echo "export NODE_PATH=$NODE_PATH:/home/$USER/npm/lib/node_modules" >> ~/.bashrc && source ~/.bashrc

->在此阶段，docker先前的设置应被销毁:

--> at this stage the docker previous setup shall be destroyed:

docker kill $(docker ps -q)
docker rm $(docker ps -aq)
docker rmi $(docker images dev-* -q)

->安装其余的先决条件:

--> Installing the rest of prereqs:

sudo apt-add-repository -y ppa:git-core/ppa
sudo apt-get update

# install git    
sudo apt-get install -y git

# Ensure that CA certificates are installed
sudo apt-get -y install apt-transport-https ca-certificates

# Add Docker repository key to APT keychain
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

# Update package lists
sudo apt-get update

# Verifies APT is pulling from the correct Repository
sudo apt-cache policy docker-ce

# Install Docker
echo "# Installing Docker"
sudo apt-get -y install docker-ce

# Add user account to the docker group
sudo usermod -aG docker $(whoami)

# Install docker compose
echo "# Installing Docker-Compose"
sudo curl -L "https://github.com/docker/compose/releases/download/1.13.0/docker-compose-$(uname -s)-$(uname -m)" \
    -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

# Install unzip, required to install hyperledger fabric.
sudo apt-get -y install unzip

->现在您可以安装Fabric开发器.环境(假设其余的prereq组件均可用):

--> now you can install Fabric dev. env. (assuming the rest of prereq components stand available):

npm install -g composer-cli  

等
