Windowsの下でnvmwを通じてNodeJS v 4.4.4.4の問題と解決方法をインストールします.
オンラインチュートリアルによるとhttps://cnodejs.org/topic/5338c5db7cbade005b023c98インストールは、最初の問題に遭遇しました.nvmw install 4.4.0実行中のエラーメッセージ404は、https://npm.taobao.org/mirrors/node/v4.4.0/x64/node.exeが見つかりません.nvmw.batファイル中のinstallフィールドを参照してください.

if %NODE_TYPE% == iojs (
  set DIST_URL=%%
  if %ARCH% == x32 (
    set NODE_EXE_URL=%NVMW_IOJS_ORG_MIRROR%/%NODE_VERSION%/win-x86/iojs.exe
  ) else (
    set NODE_EXE_URL=%NVMW_IOJS_ORG_MIRROR%/%NODE_VERSION%/win-x64/iojs.exe
  )
) else (
  if %ARCH% == x32 (
    set NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/node.exe
  ) else (
    set NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/x64/node.exe
  )
)

私はwindows 7システムです.対応するのはx64です.しかし、淘宝NPMミラースタンドとオフィシャルミラースタンドで対応するのは全部win-x64です.そこで上記のコードの最後の行をset NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/win-x64/node.exeに変えて、nvmw install 4.4.0を再実行して、エラーを継続します.

これは何の幽霊ですか引き続き検索しますhttp://www.w2bc.com/Article/78186解決策が見つかり、fget.jsのMsxml2.XMLHTTPがMsxml2.ServerXMLHTTPに修正され、nvmw install 4.4.0が再実行され、今回はダウンロードを開始しましたが、次のステップはエラーを報告します.

node v4.4.0 does not include npm

検索では4.0.0バージョンからこの問題が発見され、nvmw.batを書き換えました.記事では4.0.0バージョンに対して書き換えられたBATファイルで、4.1.0に適用されると言及しました.https://github.com/hakobera/nvmw/issues/58は、文章の内容によってnvmw.batを修正しました.その後、手動でnpm-master.zipをダウンロードし、npm.zipに改名して、nvmwディレクトリの下に新たに作成されたv4.4.0ディレクトリの下に置いて、nvmw install 4.4.0を再実行して、やっとインストールに成功しました.
最後に修正したnvmw.batを添付します.
