node.js 运行 npm 时找不到 npm-cli.js

npm-cli.js not found when running npm

提问by user1192476

Usually I can install a library using npmbut today when installing yeoman I encountered this errors. Please help to figure out what's root cause.

通常我可以使用npm安装一个库，但是今天在安装 yeoman 时我遇到了这个错误。请帮助找出根本原因。

D:\Works\phonegap\ionic\todo>npm install -g yo
    module.js:340
    throw err;
          ^
Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\bin\node_modules\npm\bin\npm-cli.js'

I looked into the folder:

我查看了文件夹：

C:\Program Files\nodejs\node_modules\npm\bin\

C:\Program Files\nodejs\node_modules\npm\bin\

but don't see node_modulesfolder as the error described.

但没有看到node_modules文件夹作为错误描述。

I also try to find npm-cli.jsand see it's actually in C:\Program Files\nodejs\node_modules\npm\bin\

我也尝试找到npm-cli.js并查看它实际上在C:\Program Files\nodejs\node_modules\npm\bin\

It turns out the issue is due to the wrong path of node in system variable. The path is currently pointing to

事实证明，问题是由于系统变量中节点的错误路径造成的。路径当前指向

(I really don't know when I modified it)

（我真的不知道我什么时候修改过）

C:\Program Files\nodejs\node_modules\npm\bin

so I change to

所以我改成

C:\Program Files\nodejs

and it works like a charm.

它就像一个魅力。

You need to run this in the command line.

您需要在命令行中运行它。

SET PATH=C:\Program Files\Nodejs;%PATH%

You may also have this problem if in your path you have C:\Program Files\nodejsand C:\Program Files\nodejs\node_modules\npm\bin. Remove the latter from the path

如果在您的路径中有C:\Program Files\nodejs和，您也可能会遇到此问题C:\Program Files\nodejs\node_modules\npm\bin。从路径中删除后者

Copy the directory named npmfrom your installed node path (In my case the npm directory was available in C:\Program Files\nodejs\node_modules).

复制npm从您安装的节点路径命名的目录（在我的情况下，npm 目录在 中可用C:\Program Files\nodejs\node_modules）。

Navigate to C:\Users\%USERNAME%\AppData\Roaming\npm\node_modulesand paste the copied npmdirectory there.

导航到C:\Users\%USERNAME%\AppData\Roaming\npm\node_modules并粘贴复制的npm目录。

This method worked for me when I had the same error. . .

This not the same case as in the question, but might be helpful for someone facing the similar issue. On Windows, if you are calling npmcommands from some CI/automation tool, you might run into the error:

这与问题中的情况不同，但可能对面临类似问题的人有所帮助。在 Windows 上，如果您npm从某个 CI/自动化工具调用命令，您可能会遇到错误：

Error: Cannot find module 'SOME_PATH\node_modules\npm\bin\npm-cli.js'

where SOME_PATHis not Program Files/...but some project directory instead. So npm tries to find npm-cli.js inside the project root directory instead of searching it in Program Files/nodejs.

whereSOME_PATH不是Program Files/...而是一些项目目录。所以 npm 尝试在项目根目录中查找 npm-cli.js 而不是在Program Files/nodejs.

The reason is npm.cmd script:

原因是 npm.cmd 脚本：

:: Created by npm, please don't edit manually.
@ECHO OFF

SETLOCAL

SET "NODE_EXE=%~dp0\node.exe"
IF NOT EXIST "%NODE_EXE%" (
  SET "NODE_EXE=node"
)


SET "NPM_CLI_JS=%~dp0\node_modules\npm\bin\npm-cli.js"
FOR /F "delims=" %%F IN ('CALL "%NODE_EXE%" "%NPM_CLI_JS%" prefix -g') DO (
  SET "NPM_PREFIX_NPM_CLI_JS=%%F\node_modules\npm\bin\npm-cli.js"
)
IF EXIST "%NPM_PREFIX_NPM_CLI_JS%" (
  SET "NPM_CLI_JS=%NPM_PREFIX_NPM_CLI_JS%"
)

"%NODE_EXE%" "%NPM_CLI_JS%" %*

This script uses %~dp0to lookup the npm-cli.js but some automation tools could set work directory in the way that %~dp0points to the local project dir so the script works incorrectly.

此脚本用于%~dp0查找 npm-cli.js，但某些自动化工具可能会以%~dp0指向本地项目目录的方式设置工作目录，因此脚本无法正常工作。

One possible solution could be changing the npm calls from this

一种可能的解决方案可能是从此更改 npm 调用

npm.cmd install

to this

对此

cmd.exe /c npm.cmd install

None of the other answers worked for me.

其他答案都不适合我。

Here is what I write (in a git bash shell on windows ):

这是我写的（在 windows 上的 git bash shell 中）：

PATH="/c/Program Files/nodejs/:$PATH" npm run yeoman

Don't change any environment variables

不要更改任何环境变量

It was the installer which caused the issue and did not install all the required file.

是安装程序导致了问题并且没有安装所有必需的文件。

I just repaired the NODEJS setup on windows 7 and it works very well. May be you can reinstall, just incase something does not work.

我刚刚修复了 Windows 7 上的 NODEJS 设置，效果很好。也许你可以重新安装，以防万一某些东西不起作用。

I encountered the same problem with node 8.5 when installed with nvm. The below solution worked for me

我在安装 nvm 时遇到了与 node 8.5 相同的问题。以下解决方案对我有用

$ nvm uninstall 8.5
8.5.0
Uninstalling node v8.5.0...Error removing node v8.5.0
Manually remove C:\Users\Omkar\AppData\Roaming\nvm\v8.5.0.

$ nvm install 8.5
8.5.0
Downloading node.js version 8.5.0 (64-bit)...
Complete
Creating C:\Users\Omkar\AppData\Roaming\nvm\temp

Downloading npm version 5.3.0... Complete
Installing npm v5.3.0...

Installation complete. If you want to use this version, type

nvm use 8.5.0

Omkar@VAST-0137 MINGW64 /d/code

This worked for me cause node 8.5 was not correctly installed before with nvm. I figured it out cause "npm\bin\npm-cli.js" folders and files were not created inside node_modules before.

这对我有用，因为在使用 nvm 之前没有正确安装节点 8.5。我发现原因是“npm\bin\npm-cli.js”文件夹和文件之前没有在 node_modules 中创建。
