安装成功后，每次新建文件时eclipse都报错，但也不影响使用，具体错误请见图，刚学习python，帮忙看看怎么回事。
问题补充：redstarofsleep 写道我的Eclipse是3.6.2JavaEE,将pydev的features和plugins放到eclipse的dropins目录下即可
你的Eclipse是什么版本?
3.3.2
问题补充：redstarofsleep 写道换个新版本的Eclipse吧..
3.4.2
3.5.2
3.6.2
问题解决了，我把那个Mylyn也装上就行了，这个是是干什么用的。
采纳的答案
Mylyn也是一个Eclipse插件,可能你那个版本的Eclipse没有自带这个插件,Pydev用到了Mylyn的一些功能吧.
Mylyn用于将任务管理和上下文管理无缝集成到Eclipse中
换个新版本的Eclipse吧..
3.4.2
3.5.2
3.6.2
我的Eclipse是3.6.2JavaEE,将pydev的features和plugins放到eclipse的dropins目录下即可

这其实是jdk版本兼容性问题。你引入的jar包编译环境(比如是1.8)要高于你android中默认的jdk编译版本(比如1.7)。要解决这个问题,就必须保证你android项目的编译jdk版本要高于等于你引入jar包的编译jdk版本,然后重新编译就好了。有两种解决方案:
1、低于等于你android的jdk版本来重新编译你要引入的jar包(不推荐)
如果引入的jar是开源框架,你要去修改jar的编译版本比较麻烦,所以不推荐
2、修改android项目的jdk版本。
可以修改android项目的jdk版本,具体修改方式如下:
Windows--&Preferences--&Java--&Compiler,然后修改默认的编译版本:

我 eclipse 用的是Version: Oxygen.2 Release (4.7.2)建议直接在 eclipse 的 help 里面的 market 里面搜索 pydev 然后安装，这样不会出错

求救，相当于少了一只手啊
要先安装jdk和配置环境变量
同样问题求助
同问，在线等
解决了，在error log右上角，出现了一个“！”，点开并更新到最新版本eclipse就可以了
最好不要用在线安装，下载离线安装包更稳定。
弄直接解压包方便多了
同问，急！
下载的Eclipse和JDK都是32位的还是64位的，要一样，还是下载离线压缩包比较方便。下载地址
文件名 最后的单词“java-neon”改成“java_neon”。不能为减号
eclipse还要安装？不是解压就可以用？
下载安装包
没事，没事，换台电脑就好了
有没有解决办法了，现在
发现不能安装在中文命名的文件夹里
eclipse官网下载最新版，傻瓜式安装都会报错?
