问题 I wonder what is the difference between caret and tilde in composer.json. Can I say it like this: caret (^) lock the first and the second version number (the 1.2 in 1.2.3) and tilde(~) lock only the first version number (the 1 in 1.2.3)? https://getcomposer.org/doc/articles/versions.md#next-significant-release-operators 回答1: From the documentation you linked: ~1.2 is equivalent to >=1.2 <2.0.0, while ~1.2.3 is equivalent to >=1.2.3 <1.3.0 ^1.2.3 is equivalent to >=1.2.3 <2.0.0 The tilde

问题 I am having trouble running commands in new version of R (4.0.1; Platform: x86_64-w64-mingw32/x64 (64-bit)) and RStudio (Version 1.3.959) which worked well in the older version of R. Let's say, I have a table named Check with more than 10,000 rows and more than 100 variables (categorical and numeric). If I try to invoke the droplevels command, I get the below message. Check <- droplevels(Check) Error in .shallow(x, cols = cols, retain.key = TRUE) : can't set ALTREP truelength However, the

问题 I have many versions on TestFlight uploaded (e.g., 1.7.1, 1.7.2, etc.). Now I want to upload the app to App Store with version 1.0, so if I select the version from TestFlight, e.g. version 1.7.1, which version will appear on App Store? I am thinking that above the image description is valid when you directly upload the app from Xcode. But due to this, I got some confusion. 回答1: Make sure version of the build and version you are creating on App Store both are same. It will show with version

问题 Is there a way to copy an S3 bucket including the versions of objects? I read that a way to copy a bucket is by using the command line tool with aws s3 sync s3://<source> s3://<dest> However, on in the source bucket I had: while in the synced bucket I have: As you can see the Version ID is "null". Is there a way to make a 100% identical copy, including the version ID? This would be important for our backups / development server, as our app is relying on the version ID. Edit: If I turn on

问题 I have a website on a server with php 4.4. (Yes, it exists) I must move it on an other hosting with php 7 I've tried in local, and it's full of errors and nothing works. For "scan" the files, I want make a script to find the old function and, after, one by one, "repair". Most of .php are "dirty scripts", not well organised but my job is only to move this website and adapt it to php7. But, I need to find the list of deprecated or incompatible functions from Php 4.4 to Php 7. Where can I find

问题 I have a spreadsheet of items which I convert to CSV and import using a custom import script into my Rails based application. The spreadsheet contains a row for each record but some rows hold different versions of previous rows. When importing the CSV I currently mark the second row using a "past_version" field but I am now thinking that implementing a full versioning gem would be a much nicer way of going about it. I have been reading through the docs for PaperTrail and it looks perfect for
