`pipenv install` 在 RPi 上超时
`pipenv install` timing out on RPi
我正在尝试在 Raspberry Pi 零 W 上启动 [pipenv][1]
。我看到的症状是在尝试 create a tutorial project.[=16 时预期超时=]
诚然,RPi 是一台小机器,但我在过程中监控内存使用情况和交换 space,并没有 运行 内存不足或交换。
知道它试图做什么吗?或者我应该如何调试它?这是堆栈跟踪:

附加信息
我注意到它在子进程调用中超时。使用 pdb,我将其追溯到命令:
<Command ['/usr/bin/python3.5', '-m', 'pipenv.pew', 'new', 'foo-su43ObVR', '-d', '-p', '/usr/bin/python3.5']>
我尝试从命令行复制该调用并且它成功完成:
pi@blue-server:~/foo $ /usr/bin/python3.5 -m pipenv.pew new 'asdf' -d -p /usr/bin/python3.5
Already using interpreter /usr/bin/python3.5
Using base prefix '/usr'
New python executable in /home/pi/.local/share/virtualenvs/asdf/bin/python3.5
Also creating executable in /home/pi/.local/share/virtualenvs/asdf/bin/python
Installing setuptools, pip, wheel...done.
这看起来很有希望,但我仍然不知道是什么原因导致超时。
TL;DR:解决方法是延长超时时间
解决了。因为 RPi Zero 很慢,所以超时了。根据线索 from the discussion on github,我注意到现在可以使用环境变量来延长默认超时。所以这解决了问题:
pi@blue-server:~/testdir $ export PIPENV_TIMEOUT=500
pi@blue-server:~/testdir $ pipenv install requests
