Fresh mermaid install crashes

[dohamann]

I had to completely reinstall my ubuntu partition and as a result tried to install mermaid cli again, using these lines:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
apt-get install -y build-essential nodejs
npm install -g mermaid.cli
mmdc -i test.mermaid -o test.png

Resulting in

(node:19211) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: spawn EACCES
(node:19211) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Node version is 8.9.0, NPM is 5.5.1

Any idea what the problem might be?
Thanks in advance!

Maybe related to #16

[kellerj]

I worked around it by copying the mermaid CSS file per the upgrade command in package.json. You have to do that and run the prepublishOnly command. Then I was able to run the dev version as node index.bundle.js

Any updates on this or any related issue?

Tested on Ubuntu 16.04.3 LTS:

yarn global add mermaid.cli
yarn global bin  # which outputs ~/.yarn/bin
cd ~/.yarn/bin
./mmdc -h
./mmdc -i flowchart.mmd -o flowchart.png

Yarn doesn't install the bin to global path which I believe is yarn's bug: yarnpkg/yarn#648

[tylerlong]

Or you can install it locally:

yarn add mermaid.cli
./node_modules/.bin/mmdc -h
./node_modules/.bin/mmdc -i flowchart.mmd -o flowchart.png

Or use NPM:

npm install mermaid.cli
./node_modules/.bin/mmdc -h
./node_modules/.bin/mmdc -i flowchart.mmd -o flowchart.png

I can confirm that it worked for me by installing it locally via yarn

Can confirm global installation works as expected on macOS Big Sur and Ubuntu 18.04 via npm install -g @mermaid-js/mermaid-cli.

Might be worth removing the warning from the README.md?

$ sudo npm install mermaid.cli -g

Do not install npm packages as root. See this article: https://medium.com/@ExplosionPills/dont-use-sudo-with-npm-still-66e609f5f92

npm install -g @mermaid-js/mermaid-cli also worked for me in Ubuntu 18.04 LTS.
