无法获取"npm install -g"可以在任何包上工作(AppData/Roaming/npm始终为空) [英] Cannot get "npm install -g" to work on any packages (AppData/Roaming/npm always empty)

问题描述

正在Windows 7 Enterprise上运行nodejs.

Running nodejs on Windows 7 Enterprise at work.

每当我安装需要-g访问的node_module时，根据经验，我知道它应该在％AppData $/Roaming/npm 中创建一个* .bat文件，但是由于某种原因，它不再做到了.

Whenever I install a node_module that needs -g access, from experience I know it's supposed to create a *.bat file in %AppData$/Roaming/npm, but for some reason it no longer does that.

例如，我将运行 npm install gulp -g ，控制台看起来像它已正确安装，但文件不在AppData文件夹中.而且，如果我尝试运行gulp命令，则会收到错误 sh.exe:gulp:命令未找到.

For example, I will run npm install gulp -g, console looks like it installed correctly, but the files will not be in the AppData folder. And if I try running a gulp command, I get error sh.exe": gulp: command not found.

如果在管理员身份控制台中运行 npm install gulp -g 命令，它将把文件安装到管理员(而不是普通用户)的％AppData％文件夹中.因此，如果我通过非管理员用户运行gulp命令，仍然会收到错误 sh.exe:gulp:命令未找到.

If I run the npm install gulp -g command in Console As Administrator, it installs the files into the %AppData% folder of the administrator (instead of the regular user). So if I run the gulp command through my non-administrator user, I still get error sh.exe": gulp: command not found.

有什么想法吗?

推荐答案

找到的解决方案:

(1)运行命令: npm config get prefix ，输出为 C:\ Program Files(x86)\ Git \ local .不知道为什么将它设置为此，因为它不是默认值.

(1) Upon running the command: npm config get prefix, output is C:\Program Files (x86)\Git\local. No idea why it was set to this, as it's not the default.

但是我使用以下代码更改了它: npm config set prefix"$ APPDATA \ npm" .

But I changed it using: npm config set prefix "$APPDATA\npm".

现在，当我安装--g模块时，即. npm install gulp -g ，它将安装到此所需目录中，不再引发 EPERM 和 ENOENT 错误.

Now when I install a --g module, ie. npm install gulp -g, it installs into this desirable directory, no longer throwing EPERM and ENOENT errors.

(2)仍然需要为npm文件夹添加一个 PATH 条目.命令 export PATH = $ PATH:/c/Users/{YOUR_USERNAME}/AppData/Roaming/npm 暂时有效，但是如果关闭控制台并再次打开，则可能无法保存(如果您不是管理员).

(2) Still need to add a PATH entry for the npm folder. The command export PATH=$PATH:/c/Users/{YOUR_USERNAME}/AppData/Roaming/npm works temporarily, but if you close console and open it again, might not be saved (if you are not an administrator).

但是您也可以使用 echo'export PATH = $ PATH:/c/Users/{YOUR_USERNAME}/AppData/Roaming/npm'>>〜/.bash_profile ，它将创建一个 .bash_profile 文件，该文件在每次打开控制台时都运行.因此，从这一点来看，它应该自动添加所需的 PATH 条目.

But you can also use echo 'export PATH=$PATH:/c/Users/{YOUR_USERNAME}/AppData/Roaming/npm' >> ~/.bash_profile, which will create a .bash_profile file, which is run each time as your console is opened. So from this point, it should automatically add the required PATH entry.
