在 MAC OS 上安装生成器超级账本作曲家时出错

Question

I am trying to install the Hyperledger Composer development environment on my Mac. But when I try to install CLI tools with the command:

npm install -g composer-cli

the following error message shows up. I have tried to rollback the node version to 6/7 without success.

npm WARN deprecated fs-promise@1.0.0: Use mz or fs-extra^3.0 with Promise Support

npm WARN deprecated crypto@0.0.3: This package is no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.

Answer 1

Use nvm and install Node version 8 - Stable. And try running by using that node version.

Answer 2

Node 9 isn't supported, python 3 won't work with npm and node-gyp. It needs to be python 2. Please see https://hyperledger.github.io/composer/stable/installing/installing-prereqs#macos to help you get the appropriate pre-reqs

Answer 3

For me it works if I uninstall everything and install NodeJs version 8 as in:

# node -v
v8.17.0
# npm -v
6.13.4

then after that install with (after apt getting node-gyp ) --unsafe-perm like:

npm install -g --loglevel error --unsafe-perm composer-cli

hope that helps...
