Are you connected to the internet? The 1st package is 12 MB.

[sherkwast]

Yes, I am connected to the internet.

[sean-mcmanus]

Hmm...I'm not reproing it. The URL is https://go.microsoft.com/fwlink/?LinkID=825339 . Are you able to access that?

[sherkwast]

Yes.And I download a zip file.

[sean-mcmanus]

Okay, we make an https request to that URL to download the zip...so I'm not sure why it would timeout in VS Code. We read the http.proxy and http.proxyStrictSLL settings from VS Code and possibly the HTTP[S]_PROXY environment variable. I don't think we've gotten other reports of this. ENOENT occurs if there's no connection at all, so it looks like your connection is just really slow and is timing out -- how long does it take before the timeout occurs?

[sherkwast]

So where should I put the zip file...

[sean-mcmanus]

Bypassing the download/install is not really recommended. We do other "install" stuff like modify the package.json. However...if you go to the install location Users(user).vscode\extensions\ms-vscode.cpptools-\

[mazhan465]

After I do these,I can open VS code normal.But When I click debug,only follows :

---

You may only use the C/C++ Extension for Visual Studio Code with Visual Studio
Code, Visual Studio or Xamarin Studio software to help you develop and test your

applications.

and debugger seems not really get into main funtion.

@Luxios we have released an update that may resolve your download issues. Please reopen if it does not.

I got same problem:

I could download https://go.microsoft.com/fwlink/?LinkID=825339 by borwser.

[sean-mcmanus]

@tallplay We're still trying to figure out why this is happening. We switched to an "improved" CDN but the results have not improved. If the link works via the browser, it implies there is some problem in our software layer. Or maybe we need to retry/wait more?

[sean-mcmanus]

@tallplay The 825339 fwlink is old. Looks like you're on 0.12.0? Can you try updating to 0.12.1 or 0.12.2 (when we release it).

[tallplay]

I've tried 0.12.2. Same problem:

The link in package.json is https://go.microsoft.com/fwlink/?linkid=853251, I could download it too.

Have any manual way to overcome this problem? I'd glad to try. I am looking forward to use the great functions of this extension.

[sean-mcmanus]

The guy who is helping us wants to know what country (and preferably city) you are in because that will help him figure out which node is having connection issues. Can you provide that? It looks like our highest number of ETIMEDOUT are coming from China, mostly Shanghai and Beijing.

As a workaround, you can open the package.json in our extension folder, look at the runtimeDependencies section and change all the fwlinks to the targets of the fwlinks (since the ETIMEDOUT is occurring on the fwlink), such as https://download.visualstudio.microsoft.com/download/pr/11025398/720d3484d8477614d89ff7a92c6fb1ee/Bin_Windows.zip (for the 853251 fwlink), and also https://download.visualstudio.microsoft.com/download/pr/11008322/220fcbe64419383a9fb722a4cdab5a92/LLVM_Windows.zip for 848957 and https://download.visualstudio.microsoft.com/download/pr/11008322/220fcbe64419383a9fb722a4cdab5a92/Microsoft.VisualStudio.VsDbg.zip for 852926.

If bypassing the fwlinks doesn't work, can you give us the error you receive? Then you could try another workaround by download the zip files using your browser, and then unzip them into the extension folder and add a install.lock file to prevent additional downloads. You might hit some issues with this though, because it skips some "install" steps we do.

I have downloaded the file. Can you tell me( and other guys) how to install it by hand? Appreciate it!

[mazhan465]

Now I can update normally.I don't know what about happen.Since one month after,it haven't happen.

[sean-mcmanus]

@mazhan465 We switched to a new CDN that reportedly works better in China, although our telemetry hasn't shown an improvement yet.
@Yensan You're failing to get results back from the fwlink (located in Massachusetts). Can you try replacing the fwlink with the actual target URL (which I gave above).

[Yensan]

@sean-mcmanus I did have replaced the fwlink with the actual target URL (which you gave above), and, there is nothing changed. Could you tell me how to install by hand?

[tallplay]

I am in Taiwan. I found it was blocked by my company's proxy. After using my phone's sharing network, everything was normal.

[Yensan]

@sean-mcmanus @tallplay Maybe it was blocked by my company's proxy too. I am in a company forbidden to access internet freely. I figure out a way to install it. Download it, then shut up cpptools' https requirement, use local python django http server to ship it. It worked fine.
My mac in my home have not encounter this problem, it works very well.
Hope VS Code and Cpptools is better and better. It make C language programming easier. Visusal Studio is too vast to make me lost.

[DatuNinuno]

@sean-mcmanus hi, i just experienced the same issue at version 1.17.2
tried to check the package.json file but the link isn't in the ones you mentioned before..
the ones here are the ff.

        "description": "C/C++ language components (Linux)",
        "url": "https://go.microsoft.com/fwlink/?linkid=859832",

        "description": "C/C++ language components (OS X)",
        "url": "https://go.microsoft.com/fwlink/?linkid=859833",

        "description": "C/C++ language components (Windows)",
        "url": "https://go.microsoft.com/fwlink/?linkid=859834",

Is there a workaround i can do to install the c++ extension..?

Update: I just found another thread like this, followed what other people suggested and managed to make it work. Basically, just set your proxy to the http.proxy parameter in the settings and it should work fine. Cheers!

[Yensan]

I have another way to ship this extension:

1. install / update in normal environment, then zip the extension file
2. download the extension file in https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools , such as ms-vscode.cpptools-0.14.0.vsix
3. transfer zip file and vsix file in special environment
4. install the extension by vsix file, and unzip the files into folder
5. enjoy it

[sean-mcmanus]

@DatuNinuno You can manually download the new fwlink binaries. Definitely don't try to use the old binaries with the new extension or the results are unpredictable and may crash or do other unintended things.

[sean-mcmanus]

@Yensan If you zip the installed/downloaded extension, there shouldn't be any need to also install the .vsix (it would just copy over files that already exist)...or am I mistaken? You may also need to use some program like tar that maintains the executable permissions (or re-run chmod to make the 2 executables runnable on Linux/Mac).
