Thank you for the detailed diagnostics.
One thing that definitely looks fishy is that in your "Try to run With Visual Studio 2019" steps it's listing a failure with an iOS path.
Also where you received "Build failed with message undefined" we do have a fix in our master branch that fixes that error. Let me get back to you with instructions for how you might try that out.

@NickGerleman there's some mention of the patching targets here, can you look and see if there's something that jumps out to you?

chrisglein picture chrisglein on 20 Apr 2020

The target failing is the standard MSBuild file copy target. React patching happens before the rest of the build, so it's possibly acting as a bit of a canary. I.e. it feels like the issue is that we're not able to write to the build directory.

One possible reason for failing to copy a file could be permissions issues. E.g. if we somehow installed the package while elevated, then tried to run the build as something non-admin, I think we could potentially see issues writing to the directory. Given we've historically required running JS tools elevated, that could be the issue. I've seen this transiently caused by antivirus locking files before as well. @ngducnghia would you mind testing the Visual Studio workflow, but running Visual Studio as an admin? I'm wondering if the CLI is seeing a different error.

@asklar do you know the build your changes for better CLI error reporting went into? Was that for the internal CLI or something external? If it's for the internal CLI in vnext, we might want to consider back-porting.

We really shouldn't be writing into node_modules as a build directory in the first place, and we've seen other issues from this. This should hopefully be fixed by the DLL distribution work @acoates-ms has been doing, since we can just package a DLL, but it seemed like we might not get that until 0.63.

NickGerleman picture NickGerleman on 20 Apr 2020

@NicholasCouri @chrisglein I think I found the root cause, Microsoft.ReactNative.SharedManaged project was unable to build because the path reach over 260 character limit. I move the project to outer folder to shorten the path and it seems to did the trick.

I'm running into another issue with temporary certificate but I guess just delete it work. I'm now able to build and run the project.

So I can build with VS 2019, but when I run npx react-native run-windows --logging it still give me following error

That sounds like you didn't get the signing cert created during the initial project creation.

@asklar , I know you made a change to help fix this in master. But am I correct in saying that running npx react-native run-windows --force from an admin cmd prompt the first time, would get the cert generated?

@acoates-ms you shouldn't need to pass --force - we pass --force to the powershell script that sets up the cert anyway. So if you are running with my changes, you should see an elevation prompt if we need to elevate.
@NickGerleman I'm not sure how to tell which branch/release/tag it went into... how do I do that?

Adding more info when I try to init project again:

ngducnghia picture ngducnghia on 21 Apr 2020

@ngducnghia interesting, I haven't run into this before.
If you're comfortable with it maybe you can help us debug what is going wrong and we could add more logging to make it easier for folks to know what to do next.

The error message is coming from here

    try {
      const timeout = 10000; // 10 seconds;
      const thumbprint = childProcess.execSync(`powershell -command "Write-Output (New-SelfSignedCertificate -KeyUsage DigitalSignature -KeyExportPolicy Exportable -Subject 'CN=${currentUser}' -TextExtension @('2.5.29.37={text}1.3.6.1.5.5.7.3.3', '2.5.29.19={text}Subject Type:End Entity') -CertStoreLocation 'Cert:\\CurrentUser\\My').Thumbprint"`, {timeout}).toString().trim();
      if (!fs.existsSync(path.join(windowsDir, newProjectName))) {
        fs.mkdirSync(path.join(windowsDir, newProjectName));
      }
      childProcess.execSync(`powershell -command "$pwd = (ConvertTo-SecureString -String password -Force -AsPlainText); Export-PfxCertificate -Cert 'cert:\\CurrentUser\\My\\${thumbprint}' -FilePath ${path.join(windowsDir, newProjectName, newProjectName)}_TemporaryKey.pfx -Password $pwd"`, {timeout});
      console.log(chalk.green('Self-signed certificate generated successfully.'));
      return thumbprint;
      } catch (err) {
        console.log(chalk.yellow('Failed to generate Self-signed certificate. Using Default Certificate. Use Visual Studio to renew it.'));
        toCopyTempKey = true;
      }

We catch an exception but we don't print out what that exception is and we don't really know which of the powershell commands failed. Could you either try running the powershell commands in that snippet from a powershell window, or add a console.log(err); to the catch block so that we know what the exception being thrown is, and report back? I'm not able to reproduce this error otherwise I'd fix it on my end without bugging you :) Thanks for the help!

@asklar I open the generator-windows/index.js in the node_modules, trying to add the log as you suggest, but then this error keep showing up on the screen
image
So I go into the .flowconfig to change it from ^0.105.0 to
[version]
^0.107.0

  • run command npx react-native-windows-init --overwrite again, this time it successfully create the certificate
    image

Then I run npx react-native run-windows but encounter another error:
image

looks like I am at the last step, I have developer mode on though

@ngducnghia that error message is best effort, it can be the developer mode failing to turn on, or as you've discovered in your case, a certificate install issue. Can you rerun the last command with --logging?

Good to hear! I actually already fixed that failure in 62 (see #4570), but since you were running npx instead of the code from RNW master, you were picking up an older version of RNW which didnt have my fix.

asklar picture asklar on 21 Apr 2020

just realized that the elevation code I added applies to installing the app but not to enabling devmode so reactivating this
