很明显，您需要安装mbstring扩展。只需转到您的php.ini并取消注释
var fileTransfer;
var uri = encodeURI("http://localhost:8000/js/test.txt");
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
fileTransfer = new FileTransfer();
fileTransfer.download(
uri,
cordova.file.dataDirectory + 'test.txt',
function(entry) {
console.log("download complete: " + entry.toURL());
},
function(error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
},
false
);
}
线。

PHP的命令行版本缺少mbstring扩展名。
运行php -i以获取信息数据。找到告诉您哪个php.ini文件已被使用的部分。编辑此文件以添加扩展名。再次运行composer命令。它应该工作。
请注意，CLI PHP通常使用与Web服务器的PHP不同的INI文件。此外，CLI PHP不需要重新启动，因为它不是一个持续运行的进程的一部分。
我的机器示例（摘录）：
Configuration File (php.ini) Path => C:\Windows
Loaded Configuration File => C:\Program Files (x86)\PHP\php.ini
Scan this dir for additional .ini files => (none)
Additional .ini files parsed => (none)

你在composer.json中为版本（用于照亮）提到了5.1。*，使其模糊不清。您需要指定特定版本，例如5.1.16删除版本中的歧义。此外extension=php_mbstring.dll你的扩展名mbstring也丢失了。
希望有所帮助。
