问题 Rust's std::process::Command allows configuring the process' stdin via the stdin method, but it appears that that method only accepts existing files or pipes. Given a slice of bytes, how would you go about writing it to the stdin of a Command ? 回答1: You can create a stdin pipe and write the bytes on it. As Command::output immediately closes the stdin, you'll have to use Command::spawn . Command::spawn inherits stdin by default. You'll have to use Command::stdin to change the behavior. Here is

问题 I have created Node js project, but my client requirement is to get its exe file so that he can run it without installing node. Kindly help me to create node.js project into its executable file i.e exe file. 回答1: I think that you have already solved your problem, but the question is not marked as resolved. You can use a packer, I prefer to use BoxedApp Packer. This program can "convert" your Node js application into an executable file. You just have to start the packer, select the file with

问题 I have a web server in Python (2.7) that uses Popen to delegate some work to a child process: url_arg = "http://localhost/index.html?someparam=somevalue" call = ('phantomjs', 'some/phantom/script.js', url_arg) imageB64data = tempfile.TemporaryFile() errordata = tempfile.TemporaryFile() p = Popen(call, stdout=imageB64data, stderr=errordata, stdin=PIPE) p.communicate(input="") I am seeing intermittent issues where after some number of these Popen s have occurred (roughly 64), the process runs
