Realm-js: Can not download realm-sync-cocoa

[kk412027247]

When i run 'react-native run-ios' after run 'yarn add realm'.
I can't download the 'realm-sync-cocoa-2.2.9.tar.gz' file.

Stop in this screen for more then 1 hour. ⬇️⬇️⬇️

When i ping static.realm.io, i can get the request, although the speed is slow.⬇️⬇️⬇️

Need some help.

@kk412027247 I can download it just fine: curl https://static.realm.io/downloads/sync/realm-sync-cocoa-2.2.9.tar.gz -O

As Realm contains encryption technology, your IP address might be blocked due to export regulations. Moreover, we have seen that some countries block access to Amazon S3 (which is hosting static.realm.io).

Finally , I solve the problem.

I find out the file /realm/scripts/download-realm.js ，then find the code,

function download(serverFolder, archive, destination) {
    const url = `https://static.realm.io/downloads/${serverFolder}/${archive}`;
    console.log('serverFolder',serverFolder);
    console.log('archive',archive);
    console.log('destination',destination)
    console.log(`Download url: ${url}`);
    return fetch(url).then((response) => {
        if (response.status !== 200) {
            throw new Error(`Error downloading ${url} - received status ${response.status} ${response.statusText}`);
        }

        const lastModified = new Date(response.headers.get('Last-Modified'));
        return fs.exists(destination)
                 .then(exists => {
                     if (!exists) {
                         return saveFile();
                     } else {
                         return fs.stat(destination)
                                  .then(stat => {
                                      if (stat.mtime.getTime() !== lastModified.getTime()) {
                                          console.log('stat.mtime',stat.mtime.getTime())
                                          console.log('lastModified',lastModified.getTime())
                                          return saveFile();
                                      }
                         })
                     }
        });

        function saveFile() {
            if (process.stdout.isTTY) {
                printProgress(response.body, parseInt(response.headers.get('Content-Length')), archive);
            } else {
                console.log(`Downloading ${archive}`);
            }
            return new Promise((resolve) => {
                const file = fs.createWriteStream(destination);
                response.body.pipe(file).once('finish', () => file.close(resolve));
            }).then(() => fs.utimes(destination, lastModified, lastModified));
        }
    });
}

I print the archive in the terminal, then found the exact path the file('realm-sync-cocoa') save in.
I replace the file and forbid this code,

 return fs.exists(destination)
                 .then(exists => {
                     if (!exists) {
                         return saveFile();
                     } else {
                         return fs.stat(destination)
                                  .then(stat => {
                                      if (stat.mtime.getTime() !== lastModified.getTime()) {
                                          console.log('stat.mtime',stat.mtime.getTime())
                                          console.log('lastModified',lastModified.getTime())
                                          return saveFile();
                                      }
                         })
                     }
        });

The project work finally.

@kk412027247 You saved my day,
I found The corrupted file in /var/folders/7q/90mfr6bd4k565n7ynbldkxzh0000gn/T/realm-sync-cocoa-3.5.6.tar.gz and replaced it with a better one.
Then editing the file you mentioned solved my problem
