我正在使用'npm oudated'命令,唯一的问题是它有点慢,因为它实际上也计算出最新版本的npm软件包。
理想情况下,我只是想知道本地是否缺少软件包,如果缺少软件包,则运行npm install。
我创建了这个脚本作为post-checkout githook,有没有更好的方法来检查你是否缺少package.json中的包?
#!/usr/bin/env node
var exec = require('child_process').exec,
missingPackage = false;
return new Promise((resolve) => {
exec('npm outdated --json', (error, stdout, stderr) => {
resolve(JSON.parse(stdout));
})
})
.then((packageJson) => {
for (const x of Object.keys(packageJson)) {
if (packageJson[x].location === '' ) {
missingPackage = true;
}
}
})
.then(() => {
if (missingPackage) {
console.log('\nHello, you are missing some packages so we are going to install them....');
exec('npm install', (error, stdout, stderr) => {
console.log(stdout);
})
}
})

我在NPM文档中没有看到任何内容,所以我就创建了这个。需要不到一秒的时间来检查您是否缺少包裹
#!/usr/bin/env node
const exec = require('child_process').exec,
fs = require('fs'),
packageJson = JSON.parse(fs.readFileSync('package.json', 'utf8')),
dependenciesPackages = Object.keys(packageJson.dependencies),
devDependenciesPackages = Object.keys(packageJson.devDependencies),
allNpmPackages = dependenciesPackages.concat(devDependenciesPackages);
// Checking if any packages are missing
return new Promise((resolve) => {
for (const [idx, npmPackage] of allNpmPackages.entries()) {
fs.readFile(`node_modules/${npmPackage}/package.json`, 'utf8', function(err) {
if (err && err.code === 'ENOENT') {
resolve(true);
} else if (idx === allNpmPackages.length - 1) {
resolve(false);
}
});
}
})
// If packages are missing then run npm install
.then((isMissingPackages) => {
if (isMissingPackages) {
console.log('\nHello, you are missing some packages so we are going to install them....'); // eslint-disable-line no-console
exec('npm install', (error, stdout) => {
console.log(stdout); // eslint-disable-line no-console
});
}
});
