我用的是Windows 10, Node 5.6.0和npm 3.6.0。我试图安装角材料和mdi到我的工作文件夹。NPM安装角材质mdi错误:

+-- UNMET PEER DEPENDENCY angular-animate@^1.5.0

+-- UNMET PEER DEPENDENCY angular-aria@^1.5.0

如何解决这个问题来安装AngularJS材质和MDI ?

我正在尝试将nodeJs安装到我的Ubuntu 14.04中，以便使用GruntJs。

我读过关于Ubuntu不同的安装方法(问题?)，所以我是这样安装它的:

sudo apt-get install npm

sudo npm install -g grunt-cli

输入grunt之后，我得到了错误:

/usr/bin/env: node: No such file or directory

所以，我试过:

curl -sL https://deb.nodesource.com/setup | sudo bash -

sudo apt-get install -y nodejs

sudo apt-get update

再次尝试，仍然得到错误，我尝试了:

sudo add-apt-repository https://launchpad.net/~chris-lea/+archive/node.js/

sudo apt-get install -y nodejs

我得到了这个信息:

nodejs is already the newest version.
0 to upgrade, 0 to newly install, 0 to remove and 3 not to upgrade.

以防万一，我试着清理了一下:

sudo apt-get autoremove

但是，错误仍然存在:当我输入grunt时，我仍然得到/usr/bin/env: node: No这样的文件或目录

我该怎么办?

刚刚遇到了这个错误:

npm ERR! code ERESOLVE

我试图安装的模块似乎与我已经安装的模块有不同的对等依赖关系。似乎npm改变了它在这方面的行为，现在让安装失败。

我现在能做些什么来弥补呢?我不想因此而降低我的React版本。

我知道有一个标记叫做——legacy-peer-deps，但我不确定这到底是什么，是否建议使用它/潜在的缺点是什么?我认为npm让安装失败是有原因的。

这很奇怪，因为直到最近我都在用纱线，而且一切都很好。

当创建一个新的Angular 5项目时:

节点版本号:8.9.2

NPM版本:5.5.1

我的命令是:

npm install -g @angular/cli

错误是:

我试图学习react，所以我有这个全堆栈react投票应用程序的示例代码，我试图让它工作，但在运行npm安装后，紧接着npm启动，当我运行npm启动时，我收到以下错误，任何人都可以帮助我解决这个问题:

我正在使用持续集成，并发现了npm ci命令。

我不知道在我的工作流中使用这个命令有什么好处。

它更快吗?这会让考试更难吗，之后呢?

我有一个下载的模块repo，我想在本地安装它，而不是全局安装在另一个目录?

有什么简单的方法吗?

我最近刚升级到npm@5。我现在有一个包锁。包含package.json中的所有内容的Json文件。我希望，当我运行npm install时，依赖版本将从锁文件中提取，以确定应该在我的node_modules目录中安装什么。奇怪的是，它实际上最终修改和重写了我的包锁。json文件。

例如，锁文件的typescript被指定为2.1.6版本。然后，在执行npm install命令后，版本被更改为2.4.1。这似乎违背了锁文件的全部目的。

我错过了什么?我如何让npm尊重我的锁文件?

在运行npm安装时看到以下错误，需要node-gyp…但可以被任何需要xcode-select的东西触发。

xcodebuild工具需要Xcode，但是是活动的 开发者目录'/Library/ developer /CommandLineTools'是一个命令 直线工具实例

有什么问题吗?

尝试从GitHub安装模块会导致以下错误:

package.json上的ENOENT错误。

容易复制使用express:

NPM安装https://github.com/visionmedia/express抛出错误。

NPM安装快速工程。

为什么我不能从GitHub安装?
