Connexion: pip install connexion[swagger-ui]：找不到匹配项：connexion[swagger-ui]

嘿@mas-dse-juremigi

我无法重现该错误。 几个问题想请教您：

1. 您一般可以安装 pip extras 吗？
2. 你从pip install connexion[tests]得到同样的错误吗？
3. pip --version的输出是什么？

这是我尝试过的：

✔ /tmp/pip > virtualenv venv
Running virtualenv with interpreter /usr/bin/python2
New python executable in /tmp/pip/venv/bin/python2
Also creating executable in /tmp/pip/venv/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
✔ /tmp/pip > . venv/bin/activate
(venv) ✔ /tmp/pip > pip install connexion[swagger-ui]

您也可以只安装swagger-ui-bundle来解锁。
尽管如此，还是有必要弄清楚为什么文档中规定的方式对您不起作用。

我们在 Windows 10 上发现了一个类似的问题。在我的开发 mac 上， connexion['swagger=ui']按预期工作。

no matches found消息可能来自 Zsh shell。 这是我系统上的完整消息（注意 zsh: 开头）：

zsh: no matches found: connexion[swagger-ui]

这是由 Zsh 文件名生成引起的，请参阅man zshexpn ：

FILENAME GENERATION
       If a word contains an unquoted instance of one of the  characters  `*',
       `(',  `|',  `<',  `[', or `?', it is regarded as a pattern for filename
       generation, unless the GLOB option is unset. If the EXTENDED_GLOB
       option is set, the `^' and `#' characters also denote a pattern; other‐
       wise they are not treated specially by the shell.

基本上，Zsh 试图将“模式”扩展为connexions 、 connexionw 、 connexiona等文件名。其他 shell（即 bash）要么没有那种扩展或默认禁用它。 对于Zsh，参数需要加引号。

看起来像zsh ：

``
hjacobs@mycomputer :~$ zsh
mycomputer% pip install connexion[swagger-ui] --user
zsh：未找到匹配项：连接 [swagger-ui]

pip install "connexion[swagger-ui]"为我工作

任何人都能够将其格式化为需求文件？

大家好，有没有人设法包含在需求文件中？

@johanngomes回复晚了，但我在尝试部署到 Google App Engine（第二代）时遇到了同样的问题。 Connexion 安装得很好，但无论出于何种原因，额外的[swagger-ui]都没有。

正如@dtkav提到的，只需将swagger-ui-bundle到您的需求文件中（这就是安装时所有额外包的作用）

以下是我使用pipenv转储requirements.txt文件时得到的输出（已删除其他依赖项）

命令：

pipenv lock -r

connexion[swagger-ui]==2.7.0
