在 ubuntu 中運行本機應用程序時出錯

Question

我是 react-native 的新手，並試圖通過閱讀此處的文檔在 react-native 中運行我的第一個應用程序。 我將我的應用程序命名為rdvTemp 。 當我在 watchman watchman/rdvTemp中運行命令react-native run-android時，出現此錯誤：

我明白這意味着安裝有問題，但不應該是這樣，因為我遵循了一切。 我安裝了 Node、react native CLI 和 watchman，而我已經有了 Java 和 Android Studio。 Java 和 Android Studio 都是最新的。 請告訴我我做錯了什么或我應該做什么。 我無法在其他地方獲得任何幫助。 謝謝...

Answer 1

第1步 ：

通過在.grade/dist找到zip文件，確保已正確安裝gradle

第2步

在yourProjectAppDir/android/gradle/wrapper/gradle-wrapper.properties文件中，將distributionUrl更改為https\\://services.gradle.org/distributions/gradle-YOUR_LOCAL_VERSION-all.zip

如果您獲得了無法鎖定任務歷史記錄緩存（ APP_NAME\\android\\.gradle\\YOUR_LOCAL_VERSION\\taskHistory ），因為它已被此過程鎖定。

您可能需要通過刪除.gradle \\ caches文件夾來清除緩存

Answer 2

我在我的 MAC 上遇到了同樣的問題，你應該給 gradle 權限：

sudo chown -R $USER ~/.gradle
