update command failed on EPERM

[amiram]

I'm using sicksync on windows with mingw. I installed sicksync globally using node 6.9.5 installed with nvm-windows.
When I run the update command I see a successful update of the remote machine but then I get an error about my local machine. After that, sicksync is not installed anymore. Error is:

That's very interesting, thanks for the issue. EPERM has to do with file-permissions issues, so it's likely the update command isn't doing something right.

I'm not terribly familiar with running node packages on windows. Could you elaborate on how you originally installed? The commands you ran and such. I'm guess that the update command isn't executing the same steps that windows and nvm-windows likely requires. Just my suspicion.

[amiram]

In windows you can install node in two ways. First is just download the installer from nodejs website. This installs node in C:\Program Files\nodejs. Second way, which is the way I use, is using nvm-windows. This is installing node in %userprofile%\AppData\Roaming\nvm\vx.x.x which create a vx.x.x folder for each version. C:\Program Files\nodejs is a symlink to the current version you set in nvm-windows. Except from that, all npm commands are the same.
BTW, do you know from the above whick command failed? Also, why is it trying to install sicksync? I already did that.

sicksync update is just a small helper utility for updating itself, which I'll admit is strange. The nice thing about this command, as opposed to manually updating, is that it will also update sicksync on your remote machines as well. Otherwise, you'd have to manually ssh into each machine and update manually, which was a bit time consuming.

I wonder if the doctor command would find anything... could you try running sicksync doctor and see what that says?

[amiram]

This is what I get for doctor:

• Checking if config is present...
  Found the sicksync config file!

• Checking config file...
  sicksync's config has all the right properties and looks good!

• Checking projects in config file...
  src has all the right properties and looks good!

• Checking host for each project
  events.js:160
  throw er; // Unhandled 'error' event
  ^

The above is probably because I used cmd.exe. If I use mingw64 I get this although I can do ssh without a problem:

$ sicksync doctor
