npm install 在 Windows PowerShell 中不起作用 [英] npm install doesn't work in Windows PowerShell

问题描述

所以我的问题是这个.我有一个带有 package.json 的项目.当我在命令提示符 (cmd.exe) 中运行npm install"时，一切都会按预期安装.但是，当我在 PowerShell (powershell.exe) 中执行完全相同的操作时，我收到一个错误:npm ERR！错误:ENOENT，打开 'c:\package.json'" 即使我在路径中运行了npm install"该项目.它总是在 c: 中搜索 package.json 出于某种原因我无法理解.

So my problem is this. I have a project with a package.json. When I in the command prompt (cmd.exe) run "npm install" everything installs as expected. However when I do the exact same thing in PowerShell (powershell.exe) I get an error: "npm ERR! Error: ENOENT, open 'c:\package.json'" even though I ran "npm install" in the path of the project. It always searches for package.json in c: for some reason I can't understand.

下面是 npm-debug.log(也写成 i c: 即使我的路径是 c:\code\myProject):

Below is the npm-debug.log (which also is written i c: even though my path is c:\code\myProject):

0 info it worked if it ends with ok

9 error command "C:\\Program Files\\nodejs\\\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install"
10 error cwd c:\

12 error npm -v 1.3.11
13 error path c:\package.json
14 error code ENOENT
15 error errno 34
16 verbose exit [ 34, true ]

我在任何地方都找不到解决此问题的方法.PATH 变量设置正确，因为 node 和 npm 本身都可以工作.

I can't find a solution to this problem anywhere. The PATH variable is setup correctly since both node and npm itself works.

推荐答案

使用 .npmrc 显式设置前缀:

Use .npmrc to set the prefix explicitly:

• 转到 \Users\%USERNAME%\.npmrc.例如，在 Powershell 中:

• Go to \Users\%USERNAME%\.npmrc. For example, in Powershell:

Notepad "\Users\$env:USERNAME\.npmrc"

设置前缀:

Set the prefix:

prefix = "C:/Program Files/nodejs"
