无法安装Swagger CodeGen [英] Trouble installing Swagger CodeGen

问题描述

我使用命令安装了Swagger CodeGen

I installed Swagger CodeGen using the command

npm install swagger-codegen -g

所以我应该安装它，但是仍然出现一些错误/故障.每次输入

So I should have it installed, but there is some error/glitch going on. Everytime I enter

swagger-codegen -v

我收到以下消息

'swagger-codegen'无法识别为内部或外部命令， 可操作的程序或批处理文件.

'swagger-codegen' is not recognized as an internal or external command, operable program or batch file.

我不知道该怎么办.我该如何解决?我正在尝试按照教程进行操作，但是讲师从未展示过他如何安装程序.

I have no idea what to do. How should I fix this? I am trying to follow a tutorial, but the instructor nevers shows how he installs programs.

在GitHub下，说明没有意义

Under GitHub, the instructions don't make sense

先决条件 如果您正在寻找最新的稳定版本，则可以直接从Maven.org(至少Java 7运行时)中获取它:

Prerequisites If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 7 runtime at a minimum):

wget http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar -O swagger-codegen-cli.jar

java -jar swagger-codegen-cli.jar help

对于Windows用户，您将需要安装wget或可以在PowerShell(3.0+)中使用Invoke-WebRequest，例如

For Windows users, you will need to install wget or you can use Invoke-WebRequest in PowerShell (3.0+), e.g.

Invoke-WebRequest -OutFile swagger-codegen-cli.jar http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar

我应该将它们放在命令行中吗?尝试过，没有用

Am I supposed to put those in the command line? tried that, didn't work

推荐答案

Swagger Codegen是Java应用程序，因此您必须安装Java.

Swagger Codegen is a Java app, so you must have Java installed.

Swagger Codegen有两个版本-2.x和3.x.对于openapi: 3.0.0定义使用3.x，对于swagger: '2.0'使用2.x.

There are two versions of Swagger Codegen - 2.x and 3.x. Use 3.x for openapi: 3.0.0 definitions and 2.x for swagger: '2.0'.

下载已编译的JAR文件:

Download the compiled JAR file:

• Codegen 3.x JAR位于此处: https://oss.sonatype.org/content/repositories/releases/io/swagger/codegen/v3/swagger-codegen-cli/

Codegen 2.x JAR位于此处: http: //central.maven.org/maven2/io/swagger/swagger-codegen-cli/

Codegen 2.x JARs are here: http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/

查找名为swagger-codegen-cli-<version>.jar的文件，例如如果需要2.3.1节:
http ://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar

Look for the file named swagger-codegen-cli-<version>.jar, e.g. if you need v. 2.3.1:
http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar

要运行代码生成，请使用:

To run the codegen, use:

java -jar c:\path\to\swagger-codegen-cli-<version>.jar <args>

(为简单起见，您可以将swagger-codegen-cli-<version>.jar重命名为swagger-codegen-cli.jar.)

(You can rename swagger-codegen-cli-<version>.jar to swagger-codegen-cli.jar for simplicity.)

使用自制软件安装:

# Codegen 3.x
brew install swagger-codegen

# Codegen 2.x
brew install swagger-codegen@2

然后，您可以按以下方式运行代码生成器:

Then you can run the codegen as:

swagger-codegen <args>
swagger-codegen@2 <args>

如果您没有Homebrew，请从Maven下载JAR文件并按照上面针对Windows的说明运行该文件.

If you don't have Homebrew, download the JAR file from Maven and run it as explained above for Windows.

您还可以:

• 从 Swagger编辑器(具有集成的代码生成器)生成服务器和客户端代码.
• 使用其 REST API 调用在线代码生成器. (示例)
• 使用Maven插件: swagger-codegen-maven-plugin .对于Codegen 2.x，组ID为io.swagger，对于Codegen 3.x，组ID为io.swagger.codegen.v3.

• generate the server and client code from Swagger Editor (it has an integrated codegen).
• call the online codegen using its REST API. (Example)
• use the Maven plugin: swagger-codegen-maven-plugin. The group ID is io.swagger for Codegen 2.x and io.swagger.codegen.v3 for Codegen 3.x.
