我在使用 AndroidStudio 时遇到问题。我刚把它安装在我的 Kubuntu 18.04 机器上，想创建我的第一个项目。 Everyhting 工作正常，项目打开。唯一的问题:我无法运行我的应用程序。我什至无法查看设计 View 中的事件 - 它永远等待构建完成。当我想运行应用程序时，它没有任何模块。
在网上搜索了一段时间后，我尝试将我的项目与 gradle 文件同步，因为这似乎可以解决类似的问题，但是一旦这样做，就会出现以下错误:

做了一次后，同步按钮就被禁用了，我不能再做一次。我必须重新启动 IDE 才能执行此操作。
我查看了 idea.log 文件以更好地追踪问题，我在那里发现了以下内容:

似乎该项目无法同步到我的 gradle 文件。运行我的应用程序的实际问题可能是基于这个问题。有没有人以前遇到过这个问题，或者可以告诉我如何解决这个问题来帮助我？
我是 AndroidStudio 和 Gradle 的新手。
最佳答案
好吧，我终于找到原因了。
问题是，我的项目文件夹与我的主文件夹位于不同的硬盘分区上。包含我的 android 项目的文件夹通过符号链接(symbolic link)链接到我的主文件夹。
我无法判断是符号链接(symbolic link)还是其他分区导致了问题。我还没有检查过。如果你把它放在同一个分区上但用符号链接(symbolic link)链接，也许它会起作用。在没有符号链接(symbolic link)的情况下在另一个分区上使用时可能会起作用。但对于遇到此问题的任何人 -> 检查其中一个是否也是您的原因。
一些额外信息:我的 android 项目文件夹驻留在用 ZFS 格式化的硬盘分区上。
关于linux - Android Studio 3.2.1 - 无法将项目与 gradle 文件同步 : Argument for @NotNull parameter 'message' of . .. 不能为空，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52937645/
我正在尝试测试是否存在表单。我是Rails新手。我的new.html.erb_spec.rb文件的内容是:require'spec_helper'describe"messages/new.html.erb"doit"shouldrendertheform"dorender'/messages/new.html.erb'reponse.shouldhave_form_putting_to(@message)with_submit_buttonendendView本身，new.html.erb，有代码:当我运行rspec时，它失败了:1)messages/new.html.erbshou
我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我在我的项目中添加了一个系统来重置用户密码并通过电子邮件将密码发送给他，以防他忘记密码。昨天它运行良好(当我实现它时)。当我今天尝试启动服务器时，出现以下错误。=>BootingWEBrick=>Rails3.2.1applicationstartingindevelopmentonhttp://0.0.0.0:3000=>Callwith-dtodetach=>Ctrl-CtoshutdownserverExiting/Users/vinayshenoy/.rvm/gems/ruby-1.9.3-p0/gems/actionmailer-3.2.1/lib/action_mailer

我已经从我的命令行中获得了一切，所以我可以运行rubymyfile并且它可以正常工作。但是当我尝试从sublime中运行它时，我得到了undefinedmethod`require_relative'formain:Object有人知道我的sublime设置中缺少什么吗？我正在使用OSX并安装了rvm。 最佳答案 或者，您可以只使用“require”，它应该可以正常工作。我认为“require_relative”仅适用于ruby1.9+ 关于ruby-主要:Objectwhenrun
我花了三天的时间用头撞墙，试图弄清楚为什么简单的“rake”不能通过我的规范文件。如果您遇到这种情况:任何文件夹路径中都不要有空格!。严重地。事实上，从现在开始，您命名的任何内容都没有空格。这是我的控制台输出:(在/Users/*****/Desktop/LearningRuby/learn_ruby)$rake/Users/*******/Desktop/LearningRuby/learn_ruby/00_hello/hello_spec.rb:116:in`require':cannotloadsuchfile--hello(LoadError) 最佳

似乎无法为此找到有效的答案。我正在阅读Rails教程的第10章第10.1.2节，但似乎无法使邮件程序预览正常工作。我发现处理错误的所有答案都与教程的不同部分相关，我假设我犯的错误正盯着我的脸。我已经完成并将教程中的代码复制/粘贴到相关文件中，但到目前为止，我还看不出我输入的内容与教程中的内容有什么区别。到目前为止，建议是在函数定义中添加或删除参数user，但这并没有解决问题。触发错误的url是http://localhost:3000/rails/mailers/user_mailer/account_activation.http://localhost:3000/rails/mai
question的一些答案关于redirect_to让我想到了其他一些问题。基本上，我正在使用Rails2.1编写博客应用程序。我一直在尝试自己完成大部分工作(因为我对Rails有所了解)，但在需要时会引用Internet上的教程和引用资料。我设法让一个简单的博客正常运行，然后我尝试添加评论。靠我自己，我设法让它进入了可以从script/console添加评论的阶段，但我无法让表单正常工作。我遵循的其中一个教程建议在帖子Controller中创建一个“评论”操作，以添加评论。我的问题是:这是“标准”方式吗？我的另一个问题的答案之一似乎暗示应该有一个CommentsController参
