设置Beeware:我无法在激活的venv中创建JAR支持文件

Question

我一直在尝试设置我的工作环境，以便我可以尝试Beeware教程。https://voc.readthedocs.io/en/latest/background/install.html

下面是使用Python3.7在Windows 8中使用Bash安装教程的步骤。我安装了所有相关软件，并配置了环境变量等。

当我试图在激活的venv中创建JAR支持文件时，会遇到这样的问题：

$ . 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)

我已经跑了一个多小时了，没有任何进展的迹象。

我非常肯定，通过venv运行脚本的导致了问题，是因为当我不使用任何venv时，进程在一分钟内就会成功运行。

当我输入cd命令时，进程似乎也不会随着时间的推移而改变。我也尝试禁用我的窗口防御程序，以提高CPU性能，而没有运气。

有什么建议是我可以做的，以使这个工作在文夫？

提前感谢

您可能想尝试使用不同的环境，例如在码头容器上。

这是一份关于Ubuntu18.04LTS截至2019年-11-29年的尝试报告.我跟着https://voc.readthedocs.io/en/latest/background/install.html

使用Python3.7代替默认的3.6。

python --version
Python 3.7.5

Java 1.8

javac -version
javac 1.8.0_25

由Ubuntu包管理器安装的ant：

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

我不得不安装python3.7venv(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，最后运行ant命令给您带来麻烦：

ant java
