为什么Travis CI无法构建Python项目?
我有一个使用微软API(Pywin32)的简单Python脚本。我能够在本地机器上成功运行该项目,但在Travis中,它抛出了一个错误-为什么Travis CI无法构建Python项目?,python,python-3.x,pip,continuous-integration,travis-ci,Python,Python 3.x,Pip,Continuous Integration,Travis Ci,我有一个使用微软API(Pywin32)的简单Python脚本。我能够在本地机器上成功运行该项目,但在Travis中,它抛出了一个错误- 100% |████████████████████████████████| 51kB 17.9MB/s Collecting pylint==2.2.2 (from -r requirements.txt (line 15)) Downloading https://files.pythonhosted.org/packages/a5/06/

在我的本地系统中,Python版本是3.6.6
,pip是18.1
。但如果您注意到Travis中,pip版本是10.0.1
。这可能是问题所在吗
我的travis.yml文件包含-
language: python
python:
- "3.6.6"
pip:
- "18.1"
install:
- pip install -r requirements.txt
script:
- python main.py
Python包pywin32==224已经存在,并且可以在我的本地机器上下载,所以我猜错误并不是来自他们
谢谢你的帮助

尝试安装Python后,出现以下错误:
0.01s$ source ~/virtualenv/python3.6/bin/activate
$ python --version
Python 3.6.3
$ pip --version
pip 9.0.1 from /home/travis/virtualenv/python3.6.3/lib/python3.6/site-packages (python 3.6)
0.08s$ choco install python3
choco: command not found
The command "choco install python3" failed and exited with 127 during .
Your build has been stopped.
编辑2-
新的.travis.yml:
language: python
python:
- "3.6"
os: windows
before_install:
- choco install python3
- export PATH="/c/Python37:/c/Python37/Scripts:$PATH"
- python -m pip install --upgrade pip wheel
install:
- pip install -r requirements.txt
script:
- python main.py
输出-

pywin32
是WinAPI包装,所以它是仅限Windows的软件包,您不能在Linux上使用它
Travis CI默认在Linux上运行,但自2018年10月起,可以通过在.Travis.yml
文件中添加os:Windows
来使用Windows。看看这个
然而,由于它的“早期访问”功能,它仍然错过了很多东西,包括。因此,如果您现在需要Python,唯一的方法就是手动安装,例如
使用Python 3.8更新了示例(2020年4月),该示例现在似乎是默认的:
- os: windows
language: sh
python: "3.8"
before_install:
- choco install python3
- export PATH="/c/Python38:/c/Python38/Scripts:$PATH"
- python -m pip install --upgrade pip wheel
我相信,默认情况下Travis运行Linux,因此那里没有WinAPI。您是否尝试在.travis.yml中添加
os:windows
?请看是的,尝试过,但不幸的是操作系统:windows不支持Python。谢谢。我来试试。更新了问题。更新后的输出看起来仍然像Linux输出。在任何情况下,您都必须有os:windows
。不,没有更改。似乎根本不支持Python。更新(编辑2)@BoudhayanDev请仔细阅读最后一个链接的内容。已经有项目成功地使用了它。您不应该使用language:python
,因为它不受支持,您必须自己安装所有需要的东西
