Tox多重install_command

Question

我怎样才能把几个命令传递给毒物检验？

这是我的尝试：

[tox]
install_command =
    python -m pip install --no-deps --install-option='--parallel 8' .
    python -m pip install {opts} {packages}

以前的配置会产生此错误：

Traceback (most recent call last):
  File "/usr/bin/tox", line 11, in <module>
    load_entry_point('tox==3.14.5', 'console_scripts', 'tox')()
  File "/usr/lib/python3.8/site-packages/tox/session/__init__.py", line 44, in cmdline
    main(args)
  File "/usr/lib/python3.8/site-packages/tox/session/__init__.py", line 64, in main
    config = load_config(args)
  File "/usr/lib/python3.8/site-packages/tox/session/__init__.py", line 80, in load_config
    config = parseconfig(args)
  File "/usr/lib/python3.8/site-packages/tox/config/__init__.py", line 269, in parseconfig
    ParseIni(config, config_file, content)
  File "/usr/lib/python3.8/site-packages/tox/config/__init__.py", line 1149, in __init__
    raise tox.exception.ConfigError(

install_command

确定用于将软件包安装到虚拟环境中的命令。

(强调我的博士学位)

也就是说，install_command必须是一个命令，而不是一个列表。如果您需要运行几个命令，创建一个shell脚本并将其用作install_command。
