在Windows上找不到全局安裝的Express.JS

Question

我試圖通過全局安裝Express-Generator，但找不到它。誰能幫忙？

我試過打開一個新的CMD/Powershell，同樣的事情發生。

PS C:\Users\testuser\testme> npm install -g express-generator 
npm http GET https://registry.npmjs.org/express-generator 
npm http 304 https://registry.npmjs.org/express-generator 
npm http GET https://registry.npmjs.org/commander 
npm http GET https://registry.npmjs.org/mkdirp 
npm http 304 https://registry.npmjs.org/commander 
npm http 304 https://registry.npmjs.org/mkdirp 
npm http GET https://registry.npmjs.org/keypress 
npm http GET https://registry.npmjs.org/minimist 
npm http 304 https://registry.npmjs.org/keypress 
npm http 304 https://registry.npmjs.org/minimist

這已在全球範圍內安裝。

任何想法？

Answer 1

請檢查您的PATH以確保它包含全球安裝模塊的位置。

在命令提示：

1. 類型npm ls -g --depth=0並注意印在輸出
2. PATH類型的第一行中的目錄，以查看是否在步驟#1發現該目錄是在路徑...

如果（何時）npm全局安裝目錄從您的PATH中缺失，則添加它應該可以解決問題。
