【问题描述】：

如何将多个命令传递给 tox？

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}

之前的配置产生这个错误：

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(
tox.exception.ConfigError: ConfigError: py27 failed with ConfigError: 'install_command' must contain '{packages}' substitution at Traceback (most recent call last):

    res = env_attr.postprocess(testenv_config=tc, value=res)

【问题讨论】：

仅供参考，github.com/tox-dev/tox/issues/715 存在跟踪问题，用于介绍 install_commands。

标签： python tox

【解决方案1】：

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——phd）

即install_command 必须是单个命令，而不是列表。如果您需要运行多个命令，请创建一个 shell 脚本并将其用作 install_command。
