Installation, Unary operator expected in cygwin, quotes?

[Ernest Wong]

Hi,
In the if statement, line 58, should there be quotes around $os?

Because, when I reran install-sdk.sh in cygwin, I got:

$./scripts/install-sdk.sh
Already up-to-date.
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 10911  100 10911    0     0  12755      0 --:--:-- --:--:-- --:--:-- 13322

bash: line 58: [: !=: unary operator expected
:Installing Node v0.12.0

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

and Googling brought this up.

Somehow install-sdk.sh worked in cygwin the first time though. I got the output saved somewhere.

Hi
Thank you for reporting this issue.
install.sh shouldn't be invoked on windows, there was a regression which is fixed by c9/core@4c64c52#diff-4b4140932aa09b9ff43e0024a639e337R96

But adding the quotes is a good idea anyway a0f4489

Please reopen if you still see any error when running install-sdk.sh
