使用sudo npm install -g topojson安装Alexanders-MacBook-Pro:topojson alexander$ geo2topo Parcel11_projected.geojson > Parcel11_topo.json
buffer.js:495
throw new Error('"toString()" failed');

Alexanders-MacBook-Pro:topojson alexander$ topojson -q 1e4 -o out.json --Parcel11Cert.shp
-bash: topojson: command not found
后，我无法将shapfile（.shp）和geojson文件转换为topojson文件。
for /r %%i in ( E:\*.pdf ) do echo %%~ti %%~zi %%i
似乎代码是在第一种情况下执行的，但是geojson太大而无法转换。在第二种情况下，无法识别命令。
知道这里可能出现什么问题吗？
