nrm常用命令及nrm ls星号不显示问题解决

一、nrm

nrm(npm registry manager )是npm的镜像源管理工具，有时候国外资源太慢，使用这个就可以快速地在 npm 源间切换。

二、nrm常用命令

1.命令 nrm ls 显示所有源

// 查看可选源
nrm ls

2.添加可选源 nrm add <registry> <url>，其中reigstry为源名，url为源的路径。

// 添加源
nrm add baidu www.baidu.com

3.切换源 nrm use 源名

// 切换源
nrm use taobao

4.删除源 nrm del baidu

// 删除源
nrm del baidu 

5.test 源名（测试源响应时长）

// 测试源
nrm test

三、nrm ls不显示星号

1、在安装nrm目录下找到cli.js,打开修改代码

 2、修改代码如下，把&&修改为||

// 源代码
config(attrs, registry).then(() => {
                console.log('                        ');
                const newR = npm.config.get(FIELD_REGISTRY);
                var customRegistries = getCustomRegistry();
                Object.keys(customRegistries).forEach(key => {
                    delete customRegistries[key][FIELD_IS_CURRENT];
                });
                if (hasOwnProperty(customRegistries, name) && (name in registries || customRegistries[name].registry === registry.registry)) {
                    registry[FIELD_IS_CURRENT] = true;
                    customRegistries[name] = registry;
                }
                setCustomRegistry(customRegistries);
                printMsg(['', '   Registry has been set to: ' + newR, '']);
            }).catch(err => {
                exit(err);
            })

// 修改后
config(attrs, registry).then(() => {
                console.log('                        ');
                const newR = npm.config.get(FIELD_REGISTRY);
                var customRegistries = getCustomRegistry();
                Object.keys(customRegistries).forEach(key => {
                    delete customRegistries[key][FIELD_IS_CURRENT];
                });
                if (hasOwnProperty(customRegistries, name) || (name in registries || customRegistries[name].registry === registry.registry)) {
                    registry[FIELD_IS_CURRENT] = true;
                    customRegistries[name] = registry;
                }
                setCustomRegistry(customRegistries);
                printMsg(['', '   Registry has been set to: ' + newR, '']);
            }).catch(err => {
                exit(err);
            })

3、再次nrm use taobao, nrm ls就可以看到星号了
