无法运行yarn安装依赖项

Question

当我在cmd提示符下键入yarn时，我看到了这一点，

yarn install v1.16.0
Error: EISDIR: illegal operation on a directory, read
    at Object.fs.readSync (fs.js:675:18)
    at tryReadSync (fs.js:540:20)
    at Object.fs.readFileSync (fs.js:583:19)
    at onUnexpectedError (C:\Program Files (x86)\Yarn\lib\cli.js:87748:106)
    at C:\Program Files (x86)\Yarn\lib\cli.js:87858:9
    at <anonymous>

这是日志文件

谁能告诉我这到底是什么问题？
