Eclipse Pydev自动完成无法处理错误：java.lang.RuntimeException：python客户端仍然没有连接回eclipse java vm

Question

我与pydev的日食在过去1 - 2年间一直没有任何问题。我不知道是什么导致它，但可能是因为我做了java升级（但是，这是第一次发生）。

问题：我的eclipse pydev autocomplete挂起并且无法正常工作。

日志：

我的Java设置：

> java -version
java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)

Java is installed at: C:\Program Files\Java (has jdk1.7.0_55 and jre7 folders)

我尝试了以下方法：

1. 重新安装java
2. 删除并读取了Workspace / pydev / Python Interpreter
3. 已禁用防火墙

我相信它是因为，java没有启动（我找不到任何名为java的进程来自taskmgr）

请帮忙

Answer 1

因此，在花了很多时间调试这个问题后，我能够解决自己的问题。

我采取了以下步骤来解决我的问题：

1. 在eclipse.ini中添加了以下右前的-vmargs 行（这允许java.exe一直启动）

   -vm

   C：\ Program Files \ Java \ jdk1.7.0_55 \ bin \ java.exe

2. 在主机文件C：\ windows \ system32 \ drivers \ etc \ hosts文件末尾添加以下行（允许\ eclipse \ plugins \ org.python.pydev_3.5.0.201405201709 \ pysrc \ pycompletionserver.py连接到java eclipse vm。注意：或者，您可以编辑\ eclipse \ plugins \ org.python.pydev_3.5.0.201405201709 \ pysrc \ pydev_localhost.py文件并替换＆＃39; localhost＆＃39; with ＆＃39; 127.0.0.1＆＃39）

   127.0.0.1 localhost

注意：我在整个会话期间都禁用了防火墙。

Answer 2

在我的情况下，我不小心将一个错误编辑到一个核心python模块（os）中，这打破了许多其他模块的导入，这导致了同样的问题。只需卸载并重新安装python就可以解决问题。
