NPM CLI返回找不到命令

Question

我创建了一个简单的CLI来使用inquirer引导项目，并已成功将其发布到NPM。但是，在安装时

npm i -g noobject

它正在成功加载和安装。运行时

noobject

在cmd行中，它确实返回"；命令未找到"；以及在运行时

npx noobject its returning the following.

npm ERR! could not determine executable to run
npm ERR! A complete log of this run can be found in:
npm ERR!     C:UsersMeAppDataLocalnpm-cache_logs2022-02-13T17_28_00_374Z-debug-0.log

我在windows 10和linux ubuntu 20.4上都试过了。这是我的index.js：https://sourceb.in/ZGZMWKU8tb

#! /usr/bin/env node
const inquirer = require("inquirer");
const fs = require("fs");
// FULL SOURCE TREE: https://github.com/vKxni/noobject
const CURR_DIR = process.cwd();
const CHOICES = fs.readdirSync(`${__dirname}/templates`);
// Questions asked to the User
const QUESTIONS = [
{
name: "project-choice",
type: "list",
message: "What project would you like to generate?",
choices: CHOICES,
},
{
name: "project-name",
type: "input",
message: "Project name:",
validate: (input) => {
if (/^([A-Za-z-_d])+$/.test(input)) return true;
else
return "Project name may only include letters, numbers, underscores and hashes.";
},
},
];
// Send a prompt to choose a template
inquirer.prompt(QUESTIONS).then((answers) => {
const projectChoice = answers["project-choice"];
const projectName = answers["project-name"];
const templatePath = `${__dirname}/templates/${projectChoice}`;
// Create the folder with the project name choosed by the user
fs.mkdirSync(`${CURR_DIR}/${projectName}`);
createDirectoryContents(templatePath, projectName);
console.log(`✅ Successfully created ${projectName}`);
});
const createDirectoryContents = (templatePath, newProjectPath) => {
const filesToCreate = fs.readdirSync(templatePath);
filesToCreate.forEach((file) => {
const origFilePath = `${templatePath}/${file}`;
const stats = fs.statSync(origFilePath);
if (stats.isFile()) {
const contents = fs.readFileSync(origFilePath, "utf8");
if (file === ".npmignore") file = ".gitignore";
const writePath = `${CURR_DIR}/${newProjectPath}/${file}`;
fs.writeFileSync(writePath, contents, "utf8");
console.log(`⚠️ Created ${writePath}`);
} else if (stats.isDirectory()) {
fs.mkdirSync(`${CURR_DIR}/${newProjectPath}/${file}`);
createDirectoryContents(
`${templatePath}/${file}`,
`${newProjectPath}/${file}`
);
}
});
};

这是我的包.json:

{
"name": "noobject",
"version": "1.2.8",
"description": "Project generator written in NodeJS",
"main": "index.js",
"scripts": {
"noobject": "node index.js"
},
"repository": {
"type": "git",
"url": "git+https://github.com/vKxni/noobject.git",
"keywords": [
"node",
"generator",
"project",
"noobject"
],
"author": "vKxni",
"license": "ISC",
"dependencies": {
"inquirer": "^8.2.0"
},
"bin": {
"noobject": "index.js"
}
}
}

您的问题是repository缺少一个}，所以bin实际上在repository内部。你可以看到倒数第二行有一个加倍的}。

{
"name": "noobject",
"version": "1.2.8",
"description": "Project generator written in NodeJS",
"main": "index.js",
"scripts": {
"noobject": "node index.js"
},
"repository": {
"type": "git",
"url": "git+https://github.com/vKxni/noobject.git",
/* <----- should be here */
"keywords": [
"node",
"generator",
"project",
"noobject"
],
"author": "vKxni",
"license": "ISC",
"dependencies": {
"inquirer": "^8.2.0"
},
"bin": {
"noobject": "index.js"
}
} /* <----- wrong place! */
}

如果你解决了这个问题，它就起作用了：

{
"name": "noobject",
"version": "1.2.8",
"description": "Project generator written in NodeJS",
"main": "index.js",
"scripts": {
"noobject": "node index.js"
},
"repository": {
"type": "git",
"url": "git+https://github.com/vKxni/noobject.git",
},
"keywords": [
"node",
"generator",
"project",
"noobject"
],
"author": "vKxni",
"license": "ISC",
"dependencies": {
"inquirer": "^8.2.0"
},
"bin": {
"noobject": "index.js"
}
}
