我已按照React Native's Android Setup Page中显示的确切说明操作并运行代码,而不会遇到任何问题。今天,我正在尝试运行完全相同的代码。它说,正如我在下面提供的那样#34;构建是成功的#34;但我发现只有android/build/intermediates/dex-cache/cache.xml
文件,而android/builid
文件夹中只有ugur@ugur-Lenovo-ideapad-510-15IKB:~/Desktop/tutorials/react native tutorial/NewPro$ react-native run-android

文件。还有以下错误as shown in this image。我想弄清楚出了什么问题。这是终端输出:
class Expense < ActiveRecord::Base
belongs_to :category
end
class Category < ActiveRecord::Base
has_many :expenses
end
class ExpensesController < ApplicationController
def index
if params[:concept] || params[:category_id]
search = "%" + params[:concept] + "%"
@expenses = Expense.where("concept LIKE ? OR category_id = ?", search, params[:category_id])
else
@expenses = Expense.order("date DESC")
end
end
end
我的操作系统是Elementary OS,Node v6.11.2,react-native-cli v2.0.1。
如果你指导我找出我的构建出了什么问题,我会很高兴的。

这与babel-preset-react-native
模块有关。试着跑,
yarn remove babel-preset-react-native
yarn add babel-preset-react-native@2.1.0
或者如果你使用NPM,
npm uninstall babel-preset-react-native
npm install babel-preset-react-native@2.1.0

在主题中回答了这个问题:https://stackoverflow.com/a/45778766/4621698
这对我有用。
解决方法:
$("button:first").on("click", function() {
var targ = $("#target"),
targHt = targ.height(),
newTargHt = targHt + 50;
targ.height(newTargHt);
});
$("button:last").on("click", function() {
var targ = $("#target"),
targHt = targ.height(),
newTargHt = targHt - 50;
targ.height(newTargHt);
});
见上文,现在babel-preset-react-native指向2.1.0。 然后,
"dependencies": {
"react": "16.0.0-alpha.12",
"react-native": "0.47.1",
"babel-preset-react-native": "2.1.0"
},
然后重新启动android或ios。

删除node_modules文件夹,然后运行命令。
npm install
然后运行项目。

尝试终止端口8081上的任何进程
如果你在MAC上,那么运行命令
sudo lsof -n -i4TCP:8081
