Web3.js: installation error with beta7

[rsaccon]

I managed to install beta5 (after installing globally lerna first), but with beta7 I get the following errror:

Robertos-MacBook-Pro:app robertosaccon$ yarn add web3
yarn add v0.27.5

Exit code: 127
Command: sh
Arguments: -c ./node_modules/lerna/bin/lerna.js bootstrap
Directory: /Users/robertosaccon/kelor/app/node_modules/web3
Output:
sh: ./node_modules/lerna/bin/lerna.js: No such file or directory

also lerna is still globally installed, so I would assume that should have been picked ...

I have the same problem (also macOS): https://github.com/ethereum/web3.js/issues/933

if you use web3 beta5 as a dependency, it will run the postinstall-script and assumes to find lerna as dependecy under ./node_modules/lerna, but in that case it would actually be found ../node_modules/lerna. I forked it and removed the ./node_modules in the postinstall-script since lerna can also be found in the path under node_modules/.bin/lerna
See https://github.com/slockit/web3.js/commit/08d20ffb675414bce638e8445a64420d37835aba

hm, the reason why i made it this way is to not make people install learn globally.
It should actually install the local lerna and have it present. Maybe because its only a devDependecy?

Any idea how to solve that without making people install learn globally?

@frozeman for what it's worth, I have lerna installed globally and still have this problem.

@frozeman This PR doesn't require having it installed globally: https://github.com/ethereum/web3.js/pull/939

Is there any workaround install web3 on Windows?

[AoDev]

Same issue with lerna, I tried to install on OSX (node 8, npm 5)

Tried versions:

• web3 0.20.0
• web3 1.0.0-beta7

Tried installing lerna locally.
Nothing worked.

Any reason it is not in web3 dependencies?

• It is not in master/develop (currently even)
• It is in devDependencies in branch 1.0 so it won't install.

[email protected] should fix that
