java.io.FileNotFoundException：in.txt，（系统找不到指定的文件）（java.io.ioexception系统找不到指定的路径）
我收到以下错误
java.io.FileNotFoundException: in.txt, (The system cannot find the file specified) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at java.io.FileInputStream.<init>(Unknown Source) at java.io.FileReader.<init>(Unknown Source) at FileTest.main(FileTest.java:50)但我可以肯定地说，我已经在src，bin和根目录下创建了一个in.txt文件。我还尝试在主要参数中指定完整目录，但仍然无法正常工作。为什么Eclipse不选择它？
import java.io.*;public class FileTest { public static void main(String[] args) { try { String inFileName = args[0]; String outFileName = args[1]; BufferedReader ins = new BufferedReader(new FileReader(inFileName)); BufferedReader con = new BufferedReader(new InputStreamReader(System.in)); PrintWriter outs = new PrintWriter(new FileWriter(outFileName)); String first = ins.readLine(); // read from file while (first != null) { System.out.print("Type in a word to follow " + first + ":"); String second = con.readLine(); // read from console // append and write outs.println(first + ", " + second); first = ins.readLine(); // read from file } ins.close(); outs.close(); } catch (IOException ex) { ex.printStackTrace(System.err); System.exit(1); } }}答案1
小编典典我获取了您的代码，并使用以下命令行参数执行了该代码：
in.txt out.txt它完全没有问题。检查您的命令行。
android – java.io.FileNotFoundException：/file/path.jpg open failed：ENOENT(没有这样的文件或目录)
private void saveImage() throws IOException {
// Todo Auto-generated method stub
InputStream header = new FileInputStream("/ClashMMA/res/drawable-hdpi/beatdown.jpg");
ParseFile file = new ParseFile(toByteArray(header));
try{
file.save();
} catch (ParseException e) {
e.printstacktrace();
}
ParSEObject displayImage = new ParSEObject("displayImage");
displayImage.put("header",file);
try{
displayImage.save();
} catch (ParseException e1){
e1.printstacktrace();
}
}
private byte[] toByteArray(InputStream header) throws IOException {
// Todo Auto-generated method stub
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int l;
byte[] data = new byte[1024];
while ((l = header.read(data,data.length)) != -1) {
buffer.write(data,l);
}
buffer.flush();
return buffer.toByteArray();
}
而我的错误是这样的;
java.io.FileNotFoundException：/ClashMMA/res/drawable-hdpi/beatdown.jpg：open Failed：ENOENT(没有这样的文件或目录)
但我确信文件在那里,因为我去了我的文件目录(在eclipse中),右键单击,然后单击copy Qualified Name.这基本上复制了文件路径.我已经尝试了一些其他路径,例如关闭我的计算机,以及我的src文件夹.有人可以告诉我我做错了什么吗？为什么它不会读取文件,实际上它在那里？详细解释请.
解决方法
你基本上有两个选择：
>将它们放入APK存档中,以便您可以使用getSystemResourceAsstream加载它们：请参阅How to load image for Android ImageView from classpath?>将文件复制到Android文件系统中,以便FileInputStream可以找到它们.

我正在尝试使用 Django 模板上传文件，但在 save_project 上我收到此回溯错误

用Idle运行Python脚本的时候发现如下错误：

FileNotFoundError: [WinError 2] 系统找不到指定的文件。
后来在stackoverflow上找到如下解决办法：
In Windows , to use echo in subprocess, you would need to use shell=True . This is because echo is not a separate executable, but rather a built-in command for the windows command line. Example -
在windows 在子进程中使用echo，需要设置 shell =True，因为 echo 不是单独的命令，而是window CMD 内置的命令
process1 = subprocess.Popen(command1,stdout=subprocess.PIPE,shell=True)
Also, please do note, you should only use shell=True when absolutely necessary (as in this case , to use echo in windows in subprocess).
并且，需要注意，只有在绝对需要的情况下才使用shell=True
找到 subprocess.py脚本，将对应行加上shell=true 参数。
