Python Interpreter not installed after installing Aptana Studio3

由 放肆的年华 提交于 2020-01-12 08:35:32
问题 I was under the impression that installing Aptana Studio 3 also installed the python interpreter. when I try to create a PyDev project it says that "Project Interpreter not specified" So it will not let me proceed. Is there any documentation on how to proceed configuring the interpreter for Studio 3? I am using the latest build of Aptana Studio 3 standalone build: 3.0.4.201108101506. Thanks In advance for any assistance. PS I have already uninstalled and reinstalled studio 3 and am still

Eclipse PyDev now shows all references to Tkinter as errors

问题 I've been using Eclipse with PyDev (on Windows, mind you) for my Python Tkinter project for about a month now, and up until recently I've had no complaints. I start the source for one module (my GUI) like so: from Tkinter import * Now, ever since I updated Eclipse to 3.6.1, it shows an error for every call to the Tkinter module( Frame() , Label() , Tk() , etc.). I thought that something might have gone wrong during the update, so I uninstalled Eclipse, re-downloaded it (Eclipse 3.6.1 Classic)

Eclipse PyDev is throwing false errors

由 一世执手 提交于 2020-01-11 09:20:49
问题 I updated PyDev (Eclipse) yesterday and now it is telling me that None, name and other reserved words/builtin functions are invalid, but the script runs just fine. I have read on this forum that the problem deals with incorrectly importing the built-ins. I have tried changing the interpreter and re-adding it but no luck. Can somebody help me please? The errors: Undefined variable main Undefined variable None Undefined variable int Undefined variable eval I am running eclipse Juno and PyDev 2

PyDev project for Google App Engine not finding webapp2

问题 I am attempting to try out Google App Engine with python. Being familiar with Eclipse, I decided to use PyDev. After some trouble, I have a hello world program working... almost. It cannot find the webapp2 import, telling me it is unresolved. I have followed all of the instructions I can find, and have the google app engine libraries linked up - I think. I have searched for webapp2 as a potential import, and cannot find this anywhere in any of the library files. I am really new to python in

Eclipse pydev 代码检查功能

C#/Java project 在编译时就能检查代码有哪些错误. python 是动态语言, 可以认为是没有编译环节, 没有编译环节意味着我们少一个检查代码错误的机会, 这应该算是动态语言的一个缺点吧! 好在, 可以借助一些代码分析工具部分地弥补这一不足. 这里列举一下pydev 的代码分析功能: ================================ 1. pydev 自带的代码分析功能 (这个功能我经常使用) ================================ 配置: preference 窗口 pydev/Editor/Code analysis 的前几个tab页. 启用状态: 默认情况下, 该代码分析功能是开启的. 多数设置我都选用默认状态, 除了Others tab, 我强化了检查的级别, 如下: Others tab: Indentation problems and mixing of tabs/spaces Warning --> Error Redefinition of builtin sysbols Warning --> Error 使用方法: 在项目树的项目节点上, 弹出快捷菜单, 选 pydev/Code analysis ================================ 2. pep8.py 代码分析功能

别了JetBrains,换Visual Studio

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Visual Studio一直是我排斥的,这么多年一致不用. 2019年JetBrains的注册码越来越频繁的被封杀,我承认使用盗版不对. 试过Eclipse+pydev搞python,但是todo用起来很不顺手,配制了很久,只有css和html的可以,python和js都不行.另外字体配置也是一大吐槽点,太麻烦了. 试过其他python写的IDE,功能不行,最后想到还有个Visual Studio,试了一下社区版,python / web / 版本管控 / 跳转到定义 / 任务列表等等这些功能也都有,关键不用担心哪天激活失效了,再想办法激活了. 安装时,如果搞python加web的话,只需要勾选" python开发 ",右边的详细信息选前四项就行,如果已经安装了python可以不选第三项的python3 补充一下:如果使用的电信的宽带,勾选了miniconda和python3的话,下载会非常非常慢,有时直接0KB/s,特别是miniconda,请做好准备. 当然了,Visual Studio的缺点就是有点大,另外代码中的todo不会高亮显示,只显示成普通的注释,任务列表的功能是正常的.版本管控的操作略有不同,别的完全没问题. 使用盗版可耻,所以我换Visual Studio Community了. 来源：

目录 安装Python python for eclipse插件安装 配置PyDev插件 测试 安装Python 从网站上下载最新的版本，从 http://python.org/download/ 下载。安装过程与其他Windows软件类似。目前稳定版本为Python 2.7.6和Python 3.3.4。 在Windows命令行中使用Python 如果你想要从Windows命令行调用Python，那么需要先设置Python环境变量。 对于Windows，点击控制面板->系统->高级->环境变量。在“系统变量”表单中点击叫做PATH的变量，然后编辑这个变量，把;D:\dev\python2.7.6加到它的结尾。当然，是Python所在的安装目录。 测试python环境变量是否设置成功 C:\Users\jiqinlin>python Python 2.7.6 (default, Nov 10 2013, 19:24:24) [MSC v.1500 64 bit (AMD64)] on win 32 Type "help", "copyright", "credits" or "license" for more information. >>> python for eclipse插件安装 1）方式一 1、下载python for eclipse python for
