json - npm - 未安装；路径中的非法字符

Question

从一个早已离去的同事那里继承了一个坏掉的 NLog 项目...

• VS2015 更新 2
• 最新 Node 安装
• 最新的 npm 更新 3.10.3
• '.net 5.0'项目(pre-core 1.0)

我的 npm Node 总是显示“npm - 未安装”

当我右键单击时，我立即得到“路径中的非法字符”

这是我的 package.json

{
"version": "0.0.0",
"name": "asp.net",
"devDependencies": {
    "gulp": "^3.9.0",
    "gulp-bower": "^0.0.11",

    "main-bower-files": "^2.9.0",
    "gulp-rename": "^1.2.2",
    "gulp-sourcemaps": "^1.6.0"
}

这是我的 project.json:

    "postrestore": [ "npm install" ],
    "prepare": [ "gulp" ]
}

这是我的 Bower.json

{
"name": "WebApplication",
"private": true,
"dependencies": {
    "bootstrap": "^4.0.0-alpha.2",
    "signalr": "^2.2.0",
    "font-awesome": "^4.5.0",
    "moment": "^2.11.0",
    "Chart-js": "^1.0.2",
    "tether": "^1.1.1",
    "bootstrap-daterangepicker": "2.1.17",
    "handlebars": "^4.0.5",
    "chosen": "^1.4.2"
}

全局.json

{
"projects": [
"src",
"wrap"
],
"sdk": {
"version": "1.0.0-rc1-update1"
}

总体问题是没有显示任何 css/样式。与我们的 iis 盒子上的内容相比，该网站看起来很简陋。

尝试全局安装 npm 包时遇到同样的问题(使用 -g 标志)。我尝试全局安装的任何 npm 包都会抛出下面给出的相同错误。

npm ERR! code EINVAL
npm ERR! path C:\Users\xxxxxxx'C:\Users\xxxxxxx\AppData\Roaming\npm
npm ERR! Illegal characters in path.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\xxxxxxx\AppData\Local\npm-cache\_logs\2021-12-15T10_49_39_874Z-debug.log

我检查了 PATH 变量。一切顺利。

在互联网上进行了一些研究后，尝试了以下命令

npm bin -g

这显示了一条奇怪的路径。

C:\Users\xxxxxx'C:\Users\xxxxxx\AppData\Roaming\npm
(not in PATH env variable)

看完this post ，我尝试设置 npm config 的路径前缀，成功了!

我是这样设置的。

npm config set prefix C:\Users\xxxxxxx\AppData\Roaming\npm

您可以检查并确认相同的使用，

npm config get prefix

理想情况下，此路径已添加到我的主目录 (C:\Users\xxxxxxx) 中的“.npmrc”文件中。如果“.npmrc”文件中没有任何其他内容(例如私有(private) npm 注册表的访问 token )，删除该文件将解决此问题。
