为react native安装choco后，npm安装不起作用

Question

我想使用react native cli，所以我安装了这个命令“choco install-y nodejs.install python2 openjdk8”，我不得不返回到其他react项目（不同的项目）并需要运行“npm install”。现在它在下面返回这组错误

我试着运行“install--global windows build tools”，也试着运行这个命令“npm install node gyp”，但它并没有解决这个问题。。。（在windows powershell、cmd和git bash上以管理员身份运行）

另外，我下载了python27并安装在路径“C:\Users\username\AppData\Local\Programs\Python”上

之后，我添加了env变量，下面有两条路径 C:\Users\username\AppData\Local\Programs\Python\Python27 C:\Users\username\AppData\Local\Programs\Python27\Scripts 但仍然不起作用

此外，我还尝试删除整个vs代码并重新下载vs代码，但效果并不理想

我甚至删除了package-lock.json和节点模块，但这不起作用

Answer 1

你能试试npm i axios或类似的东西吗。这样行吗？如果没有，试着先运行sudo。如果它仍然不起作用，你可能把你的系统搞砸了。我会尝试从web链接安装nodejs，也从web链接安装python。如果您无法以图形方式安装，可以尝试重置整个计算机，并以图形方式安装node和python

不要使用终端安装node或PythonIMO，最好转到他们的网站，通过链接进行安装，并在您的计算机上运行安装程序

Answer 2

好的。。。所以我想出来了。。我只是卸载了node js，重新安装了node js，解决了这个问题。不确定这是否是修复它的最佳方法，但它起了作用
