version

问题 I have a Node.js project that requires Node version 12 or higher. Is there a way to specify this in the packages.json file, so that the installer will automatically check and inform the users if they need to upgrade? 回答1: I think you can use the "engines" field: { "engines" : { "node" : ">=0.12" } } As you're saying your code definitely won't work with any lower versions, you probably want the "engineStrict" flag too: { "engineStrict" : true } Documentation for the package.json file can be

问题 I\'m tasked with replicating a production environment to create many test/sit environments. One of the things I need to do is build up Perl, with all the modules which have been installed (including internal and external modules) over the years. I could just use CPAN.pm autobundle, but this will result in the test environment having much newer versions of the external modules that production has. What is the easiest/best way to get and install (a lot of) version specific Perl modules. 回答1:

问题 Are there any Java APIs to find out the JDK version a class file is compiled for? Of course there is the javap tool to find out the major version as mentioned in here. However I want to do it programmatically so that that I could warn the user to compile it for the appropriate JDK 回答1: import java.io.*; public class ClassVersionChecker { public static void main(String[] args) throws IOException { for (int i = 0; i < args.length; i++) checkClassVersion(args[i]); } private static void

问题 Is there a way to upgrade the version of python used in a virtualenv (e.g. if a bugfix release comes out)? I could pip freeze --local > requirements.txt , then remove the directory and pip install -r requirements.txt , but this requires a lot of reinstallation of large libraries, for instance, numpy , which I use a lot. I can see this is an advantage when upgrading from, e.g., 2.6 -> 2.7, but what about 2.7.x -> 2.7.y? 回答1: Did you see this? If I haven't misunderstand that answer, you may try

问题 I am constantly wondering how the Java version used for Android development relates to a Java SE version. For example, I was reading today about \"Type Inference and Generic Methods\" which is a feature added in Java SE 7. I wonder to myself, \"Can I use this in Android code?\" Of course I could type the code into an Android project and see if it compiles, but I\'d be happier to have some kind of mapping in my head. I\'ve tried Googling for this info, checking the Android docs, etc, but can\

问题 I need to get the product version and file version for a DLL or EXE file using Win32 native APIs in C or C++. I\'m not looking for the Windows version, but the version numbers that you see by right-clicking on a DLL file, selecting \"Properties\", then looking at the \"Details\" tab. This is usually a four-part dotted version number x.x.x.x. 回答1: You would use the GetFileVersionInfo API. See Using Version Information on the MSDN site. Sample: DWORD verHandle = 0; UINT size = 0; LPBYTE

问题 In AssemblyInfo there are two assembly versions: AssemblyVersion : Specify the version of the assembly being attributed. AssemblyFileVersion : Instructs a compiler to use a specific version number for the Win32 file version resource. The Win32 file version is not required to be the same as the assembly\'s version number. I can get the Assembly Version with the following line of code: Version version = Assembly.GetEntryAssembly().GetName().Version; But how can I get the Assembly File Version ?

问题 I have a version resource in my resources in a C++ project which contains version number, copyright and build details. Is there an easy way to access this at run-time to populate my help/about dialog as I am currently maintaining seperate const values of this information. Ideally, the solution should work for Windows/CE mobile and earlier versions of Visual C++ (6.0 upwards). 回答1: This is an edited version of my original answer. bool GetProductAndVersion(CStringA & strProductName, CStringA &

问题 Actually I\'m a bit confused. Although I read several resources about this. For having a test of Selenium 3 using ChromeBrowser we need an extra app called ChromeDriver . I found this text from GitHub: ChromeDriver is only compatible with Chrome version 12.0.712.0 or newer. If you need to test an older version of Chrome, use Selenium RC and a Selenium-backed WebDriver instance. My question is are all ChromeDriver versions compatible with all Chrome version? No conflict between each version?

问题 I am running a node application on terminal. Have recently upgraded to node v8.5.0, but am getting this error: Error: The module \'/tidee/tidee-au/packages/tidee-au-server/node_modules/bcrypt/lib/binding/bcrypt_lib.node\' was compiled against a different Node.js version using NODE_MODULE_VERSION 51. This version of Node.js requires NODE_MODULE_VERSION 57. Please try re-compiling or re-installing the module (for instance, using `npm rebuild` or `npm install`). at Object.Module._extensions.
