packages

I am trying to use the function insertSource (new in R 2.12) to update a function that I have made changes on. However, when I use the function in this way: insertSource('filename.R', package = 'mypackage') I get the error: Error in get(this, envir = envp) : object '.cacheOnAssign' not found Unfortunately I can not come up with a simple reproducible example - if one would be helpful, please suggest how I can do it - but I have found that the following code does work: system("echo 'nls <- function(nls) return(nls)' > foo.R") insertSource('foo.R', package = stats) One difference between the

I can't get pip to install the current version of pydot (1.0.28). Though yolk and PyPi both report this version as the available, current one, pip -U pydot gives me Requirement already up-to-date: pydot in /Library/Python/2.7/site-packages Requirement already up-to-date: pyparsing in /Library/Python/2.7/site-packages (from pydot) Requirement already up-to-date: setuptools in /Library/Python/2.7/site-packages (from pydot) forcing the current version with pip -U pydot ==1.0.28 gives me Downloading/unpacking pydot==1.0.28 Could not find a version that satisfies the requirement pydot==1.0.28 (from

I'm on Mac OS X and I've heard that to avoid global installation of packages (using sudo) that might cause problems with the python files that OS X uses, the path to install python packages must be different than that of OS X. Currently python executables are installed in : /usr/local/bin/ Pip installs modules over here : /usr/local/lib/python2.7/site-packages Python is used from here : /usr/local/bin/python Are these paths safe? If you are on OS X, you should also have Python in /usr/bin : $ which -a python /usr/local/bin/python /usr/bin/python If you are using brew , the first python should

许三爷说，Ubuntu的离线安装跟屎一样。 最近的经历让我对如此不逊的言语十分赞同。 那屎一样的离线安装。 联网的日子里，安装openssh-server只需要执行： sudo apt- get install open -server 即可，工具会自动解决依赖问题。没有安装的依赖会自动安装。 Windows的日子中，一个安装包，下一步，下一步，搞定。 可是离线的Ubuntu要怎么安装openssh-server呢？ 第一次尝试官网下载deb安装包 http://packages.ubuntu.com/ 这个网站里面都是官方支持的软件包，搜索openssh-server，来到 http://packages.ubuntu.com/vivid/openssh-server 里面看到有很多依赖。我先无视之，然后点击下载amd64的版本。 执行： sudo dpkg -i xxx 然后安装不成功，我就一个一个下载依赖的，但是很快就出现了循环依赖。 程序安装不下去了，我的系统也废了。 第二次尝试“制作离线安装包” 网友莫川的做法还是值的借鉴的。网址： http://blog.csdn.net/nupt123456789/article/details/11649603 无法上网的机器是Ubuntu15.04,我在联网的虚拟机中安装了相同的系统，然后制作离线安装包。 一、下载deb安装包 $

I am wondering, how to create flexible package structure for an Android application, such that it'll be easy to extend and manage. My first idea is to put each application component in separate package, such as: spk.myapp.main.(all classes used in Main activity) spk.myapp.processor.(all classes used by Processor provider) ...and so on. However, the aspect I don't like is, that the class and package naming convention may quickly became inconsistent with other fully qualified names, such as provider authorities (in this case I would rather name these spk.myapp.processor than spk.myapp.processor

In Java, helper methods are often marked protected instead of private , so that unit tests within the same package can test the helper methods. (Specifically, I am using JUnit.) This does not seem to work in Kotlin. What access modifier is recommended instead? internal (or no modifier) works well here 来源： https://stackoverflow.com/questions/30000983/what-access-modifier-for-testable-helper-methods

Like many others, I will have a "lite" and a "pro" version of my app. They use a database, which will be in the internal storage. I would like a user to be able to buy the pro version and install it without losing the database. Partial Solution: I've seen other posts on how to have multiple apps use the same database. Essentially, this requires two things: both manifests declare the same android:sharedUserId in the manifest, one of the apps must open the database using the other app's context. I tried this and, yes, it works! The Problem: Uninstalling the lite version deletes the db. Follow

I was playing around with JShell after the Java 9 release, and I tried importing a package I made. As the entire application I'm coding it for will be contained in that package, every class but one (which I haven't coded yet) is package-private. My classpath is correct, but I still can't use any of the types declared in the package in JShell (it throws a "cannot find symbol" error). Do I need to make them public for them to be accessible, or is there some way I can test package-private classes ? Here's the exact code I tried. My current directory is C:\Users\Sylvaenn\OneDrive\Documents
