pnpm怎么切换npm
时间: 2024-04-08 11:26:31 浏览: 18
pnpm是一种替代npm的包管理工具,它具有一些独特的特性和优势。要切换使用pnpm替代npm,可以按照以下步骤进行操作:
1. 首先,确保你已经安装了pnpm。你可以通过运行以下命令来检查是否已经安装了pnpm:
```
pnpm --version
```
如果没有安装,可以通过运行以下命令来全局安装pnpm:
```
npm install -g pnpm
```
2. 安装pnpm之后,你可以使用以下命令来切换到pnpm:
```
pnpm install
```
这将使用pnpm来安装项目所需的依赖项。
3. 如果你想在全局范围内使用pnpm,可以使用以下命令来切换到pnpm:
```
npm config set package-manager pnpm
```
这将设置npm的配置,使其默认使用pnpm作为包管理工具。
需要注意的是,切换到pnpm后,你可以继续使用npm的命令,因为pnpm兼容npm的命令和功能。但是,pnpm具有一些额外的特性,例如共享依赖项和更快的安装速度。

pnpm和npm区别
pnpm 和 npm 是两种常用的 JavaScript 包管理工具,它们有以下几点区别:
1. 安装方式:npm 会将每个包都下载到项目的 `node_modules` 文件夹中,而 pnpm 采用符号链接的方式,将包安装到一个共享的存储库中,不会重复下载相同的包。
2. 空间占用:由于 pnpm 采用符号链接的方式进行安装,所以在多个项目之间共享相同的依赖包时,只需要下载一份即可,因此可以减少磁盘空间的占用。
3. 安装速度:由于 pnpm 采用符号链接的方式,并且对于相同的依赖包只需下载一次,所以在安装依赖时相对于 npm 会更快一些。
4. 环境兼容性:pnpm 目前与 npm 兼容,可以使用 npm 的一些命令和功能。但是对于一些特殊的 npm 脚本,可能需要进行额外的配置才能在 pnpm 中运行。
总而言之,pnpm 相对于 npm 来说,在磁盘空间占用和安装速度方面有一定的优势。但要注意,由于 pnpm 是相对较新的工具,在某些特殊情况下可能会出现兼容性问题。因此,在选择使用哪个工具时,可以根据具体项目的需求和实际情况进行考虑。
pnpm vs npm
PNPM and NPM are both package managers for Node.js. However, there are some differences between the two:
1. Package duplication: One of the biggest issues with NPM is package duplication. When you install multiple packages, NPM will download each package and store it in a separate folder. This can lead to a lot of duplication and increase the size of your project. PNPM on the other hand, uses a shared package system, which means that packages are stored in a single place and shared between projects. This reduces the amount of duplication and saves disk space.
2. Installation speed: PNPM is generally faster than NPM when it comes to installation speed. This is because PNPM uses a shared package system, which means that it can reuse packages that have already been downloaded. NPM, on the other hand, needs to download each package separately, which can slow down the installation process.
3. Disk space: As mentioned earlier, PNPM uses a shared package system, which means that it can save disk space by reducing package duplication. This can be beneficial if you have limited disk space.
4. Compatibility: NPM is more widely used and has better compatibility with various tools and libraries. PNPM is still relatively new and may not work with all tools and libraries.
In summary, PNPM can be a good choice if you want to reduce package duplication and save disk space. However, if you need compatibility with various tools and libraries, NPM may be a better choice.
