我试图在RMarkdown中执行Python。虽然代码块使用运行当前块按钮单独执行时输出完全正常，但在编织文档时却没有执行。下面是代码块的简单复制
q
以下是我收到的错误消息
void
bisector_of_lines(const double &pa, const double &pb, const double &pc,
const double &qa, const double &qb, const double &qc,
double &a, double &b, double &c)
{
// We normalize the equations of the 2 lines, and we then add them.
double n1 = sqrt(pa*pa + pb*pb);
double n2 = sqrt(qa*qa + qb*qb);
a = n2 * pa + n1 * qa;
b = n2 * pb + n1 * qb;
c = n2 * pc + n1 * qc;
// Care must be taken for the case when this produces a degenerate line.
if (a == 0 && b == 0) {// maybe it is best to replace == with https://stackoverflow.com/questions/19837576/comparing-floating-point-number-to-zero
a = n2 * pa - n1 * qa;
b = n2 * pb - n1 * qb;
c = n2 * pc - n1 * qc;
}
}
我甚至尝试将{python engine.path='~/anaconda3/bin/python3',python.reticulate=F}
x=[1,2,3]
print(x)
添加到running: ~/anaconda3/bin/python3 -c '
x=[1,2,3,4]
print(x)'
Quitting from lines 14-17 (Error_demo.Rmd)
Error in system2(cmd, code, stdout = TRUE, stderr = TRUE, env = options$engine.env) :
error in running command
Calls: <Anonymous> ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted
文件中，如this问题的回复中所述。但这似乎也无济于事。有人可以告诉我，我做错了什么？
