Kesalahan: Tidak dapat menentukan karakter saat ini, ini bukan string, angka, larik, atau objek dalam reaksi-asli untuk android

Setiap kali saya menjalankan react-native run-android sambil menjalankan emulator, saya mendapatkan kesalahan ini. run-ios reaksi-asli wroks sepenuhnya baik-baik saja.

A problem occurred evaluating script.
> Failed to parse React Native CLI configuration. Expected running 'npx --quiet --no-install react-native config' command from '/Users/yashatreya/Desktop/Realyze/Realyze' directory to output valid JSON, but it didn't. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global 'react-native' binaries: 'npm uninstall -g react-native react-native-cli' and try again

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Seperti yang ditunjukkan dalam pesan kesalahan, saya mencoba menjalankan npm uninstall -g react-native react-native-clitetapi tidak berhasil.

Awalnya saya mendapatkan kesalahan ini: error build react-native: Tidak dapat menemukan implementasi metode () untuk argumen [jscFlavor] pada project ': app' dari tipe org.gradle.api.Project tetapi sekarang saya mendapatkan yang di atas.

SOLUSI 1 (bekerja untuk saya)

Solusi bagi saya adalah menghapus baris berikut

apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)

Pastikan untuk menghapusnya di mana-mana. Saya memiliki baris ini di build.gradle (app) dan juga di settings.gradle .

Setelah itu, jalankan lagi npx react-native run-android konsol akan menampilkan kesalahan nyata, memperbaiki kesalahan dan mengembalikan garis yang telah Anda hapus.

Dalam kasus saya kesalahan terjadi karena saya telah menggunakan versi Node yang lebih lama dan kedua kalinya terjadi saya perlu menyinkronkan proyek saya lagi

SOLUSI 2

Hapus file yang ditemukannya kesalahan sebagai "Karakter yang dibaca saat ini adalah 'E' dengan nilai int 69"

Menghapus

app\build\intermediates\signing_config\debug\out\signing-config.json

bekerja untuk orang lain juga.

SOLUSI 3

Perbarui @ react-native-community / cli ke versi terbaru.

Pengodean yang bagus!

Saya pikir masalah ini hanya ada di versi yang lebih baru (0.61) Saya memiliki masalah yang sama dan saya hanya menggunakan versi yang lebih lama (0.60.0)

 npx react-native init AwesomeProject --version 0.60.0

Baru saja menghapus folder build di dalam android dan pergi ke folder android dan kemudian di powershell diketik ./gradlewbersih lalu cd..=>npx react-native run-android

Harap pastikan data AndroidManifest.xml dalam tanda kutip yang tepat "" bukan "". Ini biasanya terjadi ketika kita mengonfigurasi firebase dan menyalin menempel dependensi.
