我目前正在学习Express并立即做出反应,并且最初能够运行react app。在启动新的Web应用程序(昨天)时,我无法阻止新创建的反应应用程序崩溃。
My OS:
openSUSE 20180522 <br>
Kernel: x86_64 Linux 4.16.9-1-default
错误:
$ npm start
> movieapp@0.1.0 start
/home/knosence/Templates/syntelBootCamp/react/movieapp
> react-scripts start
Attempting to bind to HOST environment variable: linux-gz59
If this was unintentional, check that you haven't mistakenly set it
in your shell.

您的计算机可能有一个全局HOST
环境变量,因此Create React App会尝试在其上找到一个开放端口,而不是默认的localhost
。删除环境变量,它应该可以正常工作。
也许这个答案会对你有帮助。

我遇到了同样的问题,并使用
进行了修复import pandas as pd
path = r'C:\Temp\tmp.csv'
trg = open(path, 'w')
trg.write('col1,col2\n')
for i in range(10**6):
trg.write('{0},{1}\n'.format(i, i*2))
trg.close()
df = pd.read_csv(path, skiprows=10**5, nrows=30)
希望对其他人有帮助!
