针对第165行的错误打印
node_modules\react-native\react.gradle：
'..'不被识别为内部或外部命令，可操作程序或批处理文件
第165行是下面的第5行，从exec开始：
if (enableHermes) {
doLast {
def hermesFlags;
def hbcTempFile = file("${jsBundleFile}.hbc")
exec {
if (targetName.toLowerCase().contains("release")) {
// Can't use ?: since that will also substitute valid empty lists
hermesFlags = config.hermesFlagsRelease
if (hermesFlags == null) hermesFlags = ["-O","-output-source-map"]
} else {
hermesFlags = config.hermesFlagsDebug
if (hermesFlags == null) hermesFlags = []
}
if (Os.isFamily(Os.FAMILY_WINDOWS)) {
commandLine("cmd","/c",getHermesCommand(),"-emit-binary","-out",hbcTempFile,jsBundleFile,*hermesFlags)
} else {
commandLine(getHermesCommand(),*hermesFlags)
}
}
ant.move(
file: hbcTempFile,toFile: jsBundleFile
);
if (hermesFlags.contains("-output-source-map")) {
ant.move(
// Hermes will generate a source map with this exact name
file: "${jsBundleFile}.hbc.map",tofile: jsCompilerSourceMapFile
);
exec {
// Todo: set task dependencies for caching
// Set up the call to the compose-source-maps script
workingDir(reactRoot)
if (Os.isFamily(Os.FAMILY_WINDOWS)) {
commandLine("cmd",*nodeExecutableAndArgs,composeSourceMapsPath,jsPackagerSourceMapFile,jsCompilerSourceMapFile,"-o",jsOutputSourceMapFile)
} else {
commandLine(*nodeExecutableAndArgs,jsOutputSourceMapFile)
}
}
}
}
}
以下是android / app / build.gradle中hermescommand的定义：
project.ext.react = [
enableHermes: true,// clean and rebuild if changing
// next added by Yossi
hermesCommand: "../../node_modules/hermesengine/win64-bin/hermes",extraPackagerArgs: ["--sourcemap-output","$buildDir/intermediates/assets/release/index.android.bundle.map"]
]
据我所知，指向以下文件：
node_modules\hermes-engine\win64-bin\hermes.exe
有什么主意吗？
更新了android / app / build.gradle中的定义（遵循以下答案）：
project.ext.react = [
enableHermes: true,// clean and rebuild if changing
// -either- hermesCommand: "..\\..\\node_modules\\hermesengine\\win64-bin\\hermes",// -or- hermesCommand: "../../node_modules/hermesengine/%OS-BIN%/hermes",hermesCommand: "../../node_modules/hermesengine/%OS-BIN%/hermes","$buildDir/intermediates/assets/release/index.android.bundle.map"]
]
更改后，现在的构建输出如下：
> Task :app:bundleReleaseJsAndAssets
warning: the transform cache was reset.

解决方法
react.gradle的更多内容：
def getHermesCommand = {
// If the project specifies a Hermes command,don't second guess it.
if (!hermesCommand.contains("%OS-BIN%")) {
return hermesCommand
}
// Execution on Windows fails with / as separator
return hermesCommand
.replaceAll("%OS-BIN%",getHermesOSBin())
.replace('/' as char,File.separatorChar);
}
您要指定../../node_modules/hermesengine/win64-bin/hermes作为路径，该路径是特定于OS的（由没有OS占位符确定）。
根据注释，react.gradle因此不会再猜测您的路径，而只是将其直接传递给OS命令解释器。
此操作失败，因为您的命令解释器不允许/作为目录分隔符。
要么指定对您的系统有效的路径：
hermesCommand: "..\\..\\node_modules\\hermesengine\\win64-bin\\hermes",或指定与操作系统无关的路径，以让react.gradle为每个平台对其进行转换：
hermesCommand: "../../node_modules/hermesengine/%OS-BIN%/hermes",
