问题 I want to install biopython on Qpython3 but it says that I have python 3.2 and need version 3.3 or greater. Is there no version of QPython3 available with a higher version?

问题 I am trying to run JUnit test with a 1.5 JRE, but get the error Message: java.lang.UnsupportedClassVersionError: Bad version number in .class file When I switch to JRE 1.6 (actually a JDK but that shouldn't matter, right?) everythings works fine. So the questions are: Do we really need Java 6 for the current JUnit version? what is the newest JUnit version, that works with Java 5? 回答1: A spot check of a few classes shows that the JUnit 4.8.2 jar file was compiled with java 5, or with the java

问题 On my local testing server I'm using PHP 5.4. On the live host, however, I'm currently limited to PHP 5.3 and it must be specified in .htaccess (otherwise it defaults to 5.2). So I can add: # Use PHP 5.3 Action application/x-hg-php53 /cgi-sys/php53 AddHandler application/x-hg-php53 .php which works great on the live host but breaks the local testing server.
