设置Beeware：我无法在激活的ven中创建JAR支持文件

Question

我一直在尝试设置我的工作环境，这样我就可以尝试学习Beeware教程。 https://voc.readthedocs.io/en/latest/background/install.html
我将按照本安装教程的步骤在Windows8中使用BashShell和Python3.7。我安装了所有相关软件并配置了环境变量等

当我尝试在激活的venv中创建JAR支持文件时，我遇到了一个问题：

$ . env/Scripts/activate
(env) $ cd voc
(env) $ pip install -e .
(env) $ ant java ``` -- at this line of code the shell appears to be endlessly stuck in operation as follows:

(env) $ ant java
Buildfile: C:\Users\XXXX\tutorial\voc\build.xml

java:

compile:

compile_stdlib:
     [exec] Cloning into 'ouroboros'...
     [exec] Updating files:  17% (340/1941)

我让它运行了一个多小时，没有任何进展的迹象。
我非常确定通过venv运行脚本会导致问题的出现，因为当我不使用任何venv时，该过程会在一分钟内成功运行。**

当我输入cd命令时，进程似乎也不会随时间而改变。 我还尝试禁用windows defender以提高CPU性能，但运气不佳

有什么建议是我可以做的，让这在Venv工作

提前谢谢

您可能希望尝试不同的环境，例如在docker容器上。

下面是一篇关于2019-11-29年Ubuntu18.04LTS的试用报告

使用Python 3.7代替默认的3.6

python  version
Python 3.7.5

Java 1.8

javac -version
javac 1.8.0_25

Ubuntu软件包管理器安装的ant：

ant -version
Apache Ant(TM) version 1.10.5 compiled on March 28 2019

我必须安装Python3.7VENV，请参见How to install python3.7 and create a virtualenv with pip on Ubuntu 18.04?

sudo apt-get install python3.7-venv

克隆存储库

git clone https://github.com/beeware/voc.git

激活虚拟环境

python3 -m venv env
$ . env/bin/activate
$ cd voc
$ pip install -e .

现在终于运行了给您带来麻烦的ant命令：

ant java
Buildfile: /hd/sengo/home/wf/source/python/beeware/voc/build.xml

java:

compile:
    [mkdir] Created dir: /hd/sengo/home/wf/source/python/beeware/voc/build/java
