ERROR: can not send request; node process not running

[tomsseisums]

I installed TypeScript for Sublime for the first time and it worked like a charm. All of a sudden I am getting errors about node not running.

Excerpt from console:

spawning node module: C:\Users\psycketom\Desktop\ST3\Data\Packages\TypeScript\tsserver\tsserver.js
Found node executable at node
2015-06-15 16:48:25,048: 12592: ERROR: can not send request; node process not running

I just edited my preferences, to point to the exact node path. No success either:

spawning node module: C:\Users\psycketom\Desktop\ST3\Data\Packages\TypeScript\tsserver\tsserver.js
Found node executable at C:\Program Files\nodejs\node.exe
2015-06-15 16:58:35,129: 12448: ERROR: can not send request; node process not running

After numerous ST restarts, I found out that the problem is occasional.

And environment info:
Windows 7 x64
node v0.12.3
Sublime Text 3, build 3083

What could be the problem?

[DeezCashews]

Getting the same thing here.

Windows 7 x64
node v0.12.4
Sublime Text 3, build 3083

How are you opening Sublime? Is node in your system's PATH variable?

[zhengbli]

Is it happening on the latest bit on master? Looks like it can find the node path correctly, but cannot start it for some reason.

[DeezCashews]

Yes node is on my path. I am starting sublime from D:\<somedir>\subl as sublime is on my path too. I can run node D:\sublime3\Data\Packages\TypeScript\tsserver\tsserver.js just fine from the command line also, but sublime3 was still giving the same errors in D:\sublime3\Data\Packages\TypeScript\TS.log.

[zhengbli]

@DeezCashews is the problem also occasional for you? And is your plugin installed from the package control or cloned from the repo?

[DeezCashews]

Installed from the PackageControl. I'm not sure if it's occasional or not right now. I had it fixed temporarily I think by tweaking env, but then broke it on purpose to figure out solution for @joltmode but now I can't seem to get working again so I guess it could be occasional.

[DeezCashews]

Ok, so I figured out WHAT is breaking it, but no idea why...

Executing D:\sublime3\subl.exe = errors above
Executing D:\sublime3\sublime_text.exe = lovely code assist from tsserver.js :)

Note: The Windows installation provides a separate subl.exe, this is not a symlink to the usual executable as is often recommended as part of setup on *nix installs

I must have accidentally opened it with sublime_text.exe before with an Open With... from the Windows Shell before, I almost always use subl from the command line).

Can anyone try to repeat?

[DeezCashews]

@joltmode are you using subl.exe also? If so, try using sublime_text.exe instead and let us know what happens.

[zhengbli]

Interesting. I didn't know that subl.exe could be different from sublime_text.exe. I'll do more research on that.

[DeezCashews]

Well it's only 140k vs the 5.5M so it's not just a copy or anything, but yeah, no idea why. A complete shot in the dark would be it obviously has to execute the actual sublime_text.exe somehow, so perhaps it is then being executed with different privileges than the Windows user executing it directly. I just mention this because a lot of sublime plugins seem to write to temp directories which is often set to C:\Users\AppData\Local\Temp. While temp dirs might not have privelege issues, something else might (like say, requesting a port to listen on?).

Edit I think we'd have our answer quicker if an exception wasn't being swallowed HERE

[DeezCashews]

Well, more power to you guys for writing python because the last half hour figuring out proper indentation, simple exception handling, etc. was brutal for me, but I managed to learn a little and modified the code to get you this information:

Traceback (most recent call last):
  File "D:\sublime3\Data\Packages\TypeScript\libs\nodeclient.py", line 69, in __init__
    stdin=subprocess.PIPE, stdout=subprocess.PIPE,startupinfo=si)
  File "./subprocess.py", line 789, in __init__
  File "./subprocess.py", line 1026, in _get_handles
  File "./subprocess.py", line 1038, in _make_inheritable
OSError: [WinError 6] The handle is invalid

[zhengbli]

@DeezCashews Thanks for all the research! Looks like this is related http://www.sublimetext.com/forum/viewtopic.php?f=3&t=2464. Somebody else has this problem too (SublimeText/CoffeeScript#82), it seemed to be a path problem for them. I'm still looking.

[zhengbli]

Since I can't repro the problem on any of my machine, can you do a print(node_path) before line 69 in nodeclient.py to see if the path is right?

[DeezCashews]

Ahhh, interesting. One more set of tests given that info shows:

1. Both sublime_text.exe and subl.exe fail from the command line
2. Double clicking sublime_text.exe works but double clicking subl.exe still causes error
3. start sublime_text.exe works from command line but start subl.exe still causes error

And to answer your question: node_path is just "node" as assigned previously because os.name == "nt"
